4 How to Use this Guide Use this guide to select the linear guide ball slides, rails and accessories that you need for your application. Pages 4, 12, 20, 21, 22 and 31 provide identification numbers that you will need to order the components for your application. If you have any uncertainties, or would like more detailed information about any aspect of linear guides, please contact your representative at one of our locations listed on the back cover. FEATURES Interchangeability of Rail and Ball Slide One important manufacturing feature of the Gothic Arch is the ability to make highly accurate measurements on both the ball slide and rail, allowing for tight tolerance control, resulting in interchangeability. This means that additions and/or replacement of ball slides is easily done. High Load Capacity and Long Life has developed an infinite ball recirculating type linear guide with the largest load capacity available (comparing equal size ball slides). This high load capability helps to ensure long life. Compact Low profile Type To minimize space, has developed low profile linear guides to handle various applications. Miniature and Miniature Wide Type Stainless Steel If light loads and corrosive conditions are present for your application needs, can supply a miniature and miniature wide type linear guide in stainless steel. s built-in ball retainer system allows for easy installation and removal of ball slides. Wide Type If your application requires low profile combined with high load, offers the wide series linear guides. Shock Resistant Design Another design feature of the Gothic arch is its ability to absorb vertical shock loads from above using four-row groove configuration. This design is favorable in case of unexpected accidents during installation, or the operation of equipment. The ball groove is designed to avoid edge loading under extreme loads, extending the life of the unit. DF Arrangement 2 point contact Normal load is carried on the top two grooves. Shock load is carried by all four grooves. Universal Slider has incorporated both thru and tapped holes into one flanged slider for a combination of mounting applications. (EM/EMZ replaces EL/ELZ and FL/FLZ GM/GMZ replaces HL/HLZ and GL/GLZ) Ability to Butt Rails Tolerance of ball grooves on the ball slides and rails are controlled to allow for butting, giving you the flexibility of unlimited lengths. We can offer a stocked linear guide rail with versatility in assembling preloaded or clearance type ball slides. K1 Maintenance Free Lubrication System has the K1 for all five series of interchangeable linear guides. These lubricating units are all available from stock. Maximum Rail Length in one section available up to 4,000 mm. Short Delivery Time We can ship from our large inventory, both standard and custom cut-to-length linear rails. Fluoride Low Temperature Chrome Plating has a plating, available from stock, for linear bearings and rails to cover conditions requiring wet, corrosive and clean room applications. also offers Armaloy coating upon request.

The amount of preload is specified by size as follows. Table 1 Unit: µm Size #15 #20 #25 #30 #35 #45 #55 #65 Clearance 15~ 4 15~ 5 Preloaded 0~ 4 0~ 5 0~ 7 0~ 9 4

7 Accuracy Standard The accuracy standard of the High Load Capacity LH-Series is shown in Table 1. With highaccuracy control of individual rail size and interchangeability, the accuracy of Table 1 can be maintained sufficiently even after addition or replacement of the ball slide. Load Rating and Life The LH-Series is based on a design applying load from above. Therefore the dimension table shows the basic dynamic load rating C and basic static load rating C 0 for the downward direction. If the load is applied laterally or upward refer to values in Table 2.

32 K1 Maintenance-Free Lubrication System The K1 s distinctive capabilities as a compact and efficient oil-impregnated lubrication unit as well as a seal, greatly increases the performance of the Linear Guide. The K1 Lubrication Unit is available in two types, one for industrial applications and one for food and medical devices where cleanliness and safety are paramount. Features: 1. Long-term, maintenance-free usage. In mechanical environments where lubrication is difficult to apply, long-term running efficiency is maintained by using the K1 in combination with grease. 2. Prevention of oil-related environmental pollution. In locations where oil greatly affects the environment, or in mechanisms with severe hygiene restrictions, sufficient lubrication is provided using the K1 in combination with grease. 3. Effective in environments where the lubricant is washed away. In facilities where mechanisms are washed down with water, or subject to severe weather conditions, long service life is ensured by using the K1 in combination with grease. Especially effective under hygenic conditions where oil must not be dispersed. 4. Maintains efficiency in dusty environments. In environments where oil and grease-absorbing dust is produced, long-term efficiency is maintained by using the K1 in combination with grease. 30

35 Linear Guide: Handling Precautions linear guides are high quality and are easy to use. places importance on safety in design. For maximum safety, please follow precautions as outlined below. (3) Precautions in use (1) Lubrication Do not contaminate. Temperature limitation. Do not hang upside down. a. Remove the rust preventative rail-coating before installation. If you are using oil as a lubricant, consult for compatibility issues with the pre-packed factory grease. (2) Handling Confirm lubrication. a. Make every effort not to allow dust and foreign objects to enter. b. The temperature of the place where linear guides are used should not exceed 80 C (excluding heat-resistant type linear guides). A higher temperature may damage the plastic end cap. Handle with care. Do not drop. Do not disassemble. Do not use direct force. c. If the user cuts the rail, thoroughly remove burrs and sharp edges on the cut surface. d. When hanging upside-down (e.g. the rail is installed upside-down on the ceiling in which the ball slide faces downward), should the end cap be damaged, causing the balls to fall out, the ball slide may be detached from the rail and fall. For such use, take measures including installing a safety device. (4) Storage a. Interchangeable ball slides (randomly matching types between rail and ball slide) are installed to the provisional rail when they leave the factory. Handle the ball slide with care during installation to the rail. b. Do not disassemble the guide unless absolutely necessary. c. Ball slide will move easily. Make sure that the ball slide does not disengage from the rail. Store in the correct position. a. Linear rail may bend if stored inappropriately. Place it on a suitable surface, and store it in a flat position. d. Standard end cap is made of plastic and may break if a direct force is applied. Installation Procedures Thank you for choosing linear guides. This manual briefly describes the recommended handling and installation of linear guides for general industrial use. There are two methods of installing linear guides. The first uses a datum shoulder on the mounting base and provides accurate horizontal alignment in the same way used for machine tools. The other method uses the first rail as a reference for the second rail and is generally used when smooth motion versus high accuracy is required. recommends the interchangeable series LH and LS linear guides Provisional Rail for general industrial applications. Their self-aligning feature means a greater tolerance for alignment errors and less time spent on installation. Also, they are interchangeable between rail and slider, easily allowing the addition or replacement of parts. For interchangeable LH and LS Series linear guides, the ball slides and the rails are stocked separately. The ball slides are mounted on plastic provisional rails that allows for easy transfer of the ball slide to and from the steel rail. 33

36 The ball slides are designed with retaining wires to prevent the balls from falling out when they are removed from the rail. However, recommends that the ball slides should be stored on a provisional rail prior to installation to prevent contamination from dust and other foreign objects. The following is a description of how the ball slide should be removed from and replaced on the linear guide rail. The ball slide is held on the provisional rail using a rubber band. The rubber band should catch the bottom channel in the provisional rail and then twist around to secure the ball slide. When transferring the ball slide from the provisional rail onto the rail, or vice versa, butt the provisional rail up against the rail and slide the ball slide directly from one onto the other. It is a good idea to secure the ball slide onto the provisional rail with a rubber band after removal from the rail. Provisional rail. Linear guide rail. If a ball is accidentally dropped from the ball slide, it should be cleaned and replaced to the appropriate groove. The correct groove can be determined by the size of the clearance between the balls (the groove missing the ball will have greater clearance than the other grooves). It is normal to have a gap of 1.5 ball diameters in each groove. The following section describes how to install the linear guides on the machine. Ball slides and rails are supplied separately. Each is wrapped in vinyl sheet, and packed in a container. Plastic and brass rail caps are an available option for use in high contamination areas to prevent debris build-up in the bolt holes which may damage the slider. Please request these at time of order. 34 Brass cap. Plastic cap.

37 The rail is always shipped with rust preventive oil, which should be wiped off before use. LH and LS Series ball slides are pre-packed with grease, so no cleaning is required prior to installation. Now the linear guide is ready for installation. Place it carefully on the mounting surface. For Smooth Motion of General Machinery Snugly tighten the mounting bolts temporarily so that the rail is firmly against the bed. Then tighten the bolts with a torque wrench to the specified torque starting from one end. In linear guides, the mounting bolt holes are processed after heat treatment using a precision machining center; therefore, the bolt hole pitch accuracy is as good as the positioning accuracy of the machine, which is considered very good. When tightening the bolts, be sure to start at one end and work in order to the other end. If the bolts are tightened at the middle first, it tends to leave the rail curved. If you suspect this has happened, loosen the bolts and start again. The rail that has been tightened can now be used as a reference rail. Using a vernier caliper or other accurate tool, measure the distance between the two rails, and adjust each end until they are the same. Tighten a bolt snugly at each end of the rail. The next step is to install the table, and to use the table to align the rails. Firmly bolt the table to ball slides 1 and 2 on the firmly secured rail as shown in the diagram. Then position ball slide 3 at the left end of the adjusting rail, and bolt the table to this ball slide. Move the ball slide 3 to the right and bolt the table to the ball slide 4. Move the table to one end of the rails, and start tightening the adjusting rail bolt sequentially to the specified torque while checking excessive friction of table movement. Continue moving the table down the rail tightening each adjacent bolt until they have all been tightened. This method of assembly is for general industrial machinery where smooth linear motion is the overall objective. When precision accuracy is required, read on to the following procedure. 35

38 For Greater Accuracy of General Machinery When bolting the first rail on the machine base, align it straight using a straightedge and a dial indicator. Bolt on the rail at both ends lightly, and position a straightedge beside it. Set the straightedge parallel to the rail measuring distance A1 and A2 by a vernier caliper or some other accurate measuring tool. Move the dial indicator along the straightedge, and take readings at every bolt hole along the rail. Make fine adjustment of the rail to the straightedge until the desired reading is made, and tighten the bolt to the specified torque. When all of the bolts have been tightened, slide the dial indicator from one end of the rail to the other to ensure that the desired straightness has been achieved. Position the dial indicator on two ball slides on the reference rail as shown in the diagram. Tighten bolts of the adjusting side rail sequentially from the one end while noting the reading of the dial indicator. Straightness of linear guides is controlled so that it can be easily adjusted manually for easy installation. During installation, it is recommended that accuracy is checked to ensure smooth operation. This section describes the allowable tolerances for installation in order to maximize the performance of linear guides. We recommend that the mounting errors e1 or e2 do not exceed the values shown in the table below. Recommended allowable installation error of the LS Series (Maximum) Unit: µm Item Model No Clearance Type Preload Type Z Permissible values of parallelism in two rails : e1 Permissible values of parallelism (height) in two rails : e2 Permissible values of parallelism in two rails : e1 Permissible values of parallelism (height) in two rails : e /500mm /500mm Recommended allowable installation error of the LH Series (Maximum) Unit: µm Item Model No Clearance Type Preload Type Z Permissible values of parallelism in two rails : e1 Permissible values of parallelism (height) in two rails : e2 Permissible values of parallelism in two rails : e1 Permissible values of parallelism (height) in two rails : e /500mm /500mm If the error readings are equal to or less than the above values, you have correctly assembled the parts. For maximum accuracy, keep the readings below what is shown in the table. If your readings are greater than these values, it is necessary to remove the parts and start over.
