COUNT ON THE HYDRAULICS EXPERT Caterpillar Heavy Duty Bolted Cylinders are designed to withstand higher forces when compared to the Medium Duty Threaded Cylinder product line. This is accomplished through the use of bolted heads, thicker tube walls and higher-grade materials. This product line also offers cylinders with larger diameters and lengths. Cat cylinders feature an innovative sealing system that utilizes proprietary designs and materials to deliver superior performance. The sealing system is designed to better absorb pressure spikes, increase the ability to withstand side loading, and prevent contaminants from entering and hydraulic fluid from leaving the cylinder. The seal materials provide extended seal life across a wider temperature range, improved wear resistance and compatibility with biodegradable oils. Cat cylinder rods are induction hardened prior to chrome plating. Induction hardening prevents rod bending and chrome plating improves corrosion resistance, which allows the rods to remain rust free in excess of 96 hours during an ASTM method salt spray test. These processes also work in combination to provide increased rod protection from nicks and scratches caused by rocks and debris, which can cause decreased seal life and deterioration of the rod over time. The rods are bonded to the eyes using inertia welding, creating a superior joint for unmatched strength. Inertia welding eliminates the defects associated with arc welding known to weaken the joint. A nut attaches the cylinder piston to the rod, resulting in a higher strength joint. Cat cylinders are designed to be tougher and more robust than competitive brands, through an optimum combination of tube wall thickness and material strength. The material used resists shattering. The inner diameter of the tube is skived and burnished to assure concentricity and straightness and provide a superior finish for better sealing and longer life. The thicker tube walls allow for remanufacturing capability. KEY FEATURES The cylinders can be rehoned, up to three times in some instances, and when combined with Caterpillar's replacement seal kits, can extend the useful life of the cylinder. You can rely on a consistent product because Caterpillar uses standardized manufacturing processes and uniform, quality materials. Each cylinder is tested before it leaves our factory to ensure a quality product. As an original equipment manufacturer (OEM), you know how important it is to find a world class supplier that cares about their product as much as you do about yours. Induction hardening beneath the surface increases the rod s resistance to nicks and dents. Eye Rod Continuous Weld Inertia welding provides a continuous bond for unmatched strength.

SELECTING A CYLINDER STEP 1 Are the cylinder bore and rod diameters known? If yes, go to step 4. If no, go to step 2. STEP 2 Determine the bore diameter. Determining the bore diameter is an interactive process depending on your constraints. The following is an example of how the bore diameter is determined. The example assumes that the force required and system pressure are known. The equations can be used differently if you have different constraints or assumptions. Example: Known requirements: If system pressure is 300bar and minimum extension force is 600kN, the bore size can be found using this equation: Bore diameter(mm) = ( Force(kN) x 40,000 ) π x Pressure(bar) = 159.6mm Select the bore size from the charts on p. 10-11 that is equal to or the next size larger than the diameter that was calculated above. Selecting the size equal to or the next size larger than what you need will provide the lowest cost solution that will overcome the extension force. In the example, the next largest bore size is 160mm. To calculate the force for a given bore size and known pressure, use the following equation: π 2 Force(kN) = Pressure(bar) x x (Bore diameter mm) 40,000 If the units are different than above, convert them to metric units using the English to metric conversion equations on page 7, then use the above equations. STEP 3 Determine the rod diameter. Determining the rod diameter is an interactive process depending on your constraints. The following is an example of how a rod diameter is determined. The example assumes that the bore size, retract force required, stroke and system pressure are known. The equations can be used differently if you have different constraints or assumptions. Example: Known requirements: Bore size = 160mm, Minimum retract force = 300kN, Stroke = 1000mm, Pin to Pin Length = 1622mm and the System Pressure = 300bar: Rod diameter(mm) = ( Bore diameter(mm) ) 2 ( Retract force(kn) x 40,000 ) π x Pressure(bar) = 113.4mm In order to meet the retraction force, the rod diameter must be less than or equal to the value calculated above. Review the tables on pages 10-11 to find the rod diameters available for the selected bore size, in this example 160mm. The available rod sizes for an 160mm bore are: 70, 75, 85, 90 and 110mm. All rod sizes will meet the minimum retraction force required, however, the max stroke, min and max pin to pin length, pressure rating and max full extension length must be checked to ensure it will meet the application requirements. In this example, the max full extension length, which is equal to the stroke plus the pin to pin length, is 2622mm. When all of the parameters are checked against the tables for a bore of 160mm, only a cylinder with a rod of 110mm meets all the criteria, therefore the rod size selected for this example is 110mm. 6

STEP 4 Determine if the bore size and rod diameter meet your other requirements. You may have cycle times, flow, and pressure constraints. Use these equations to determine if the selected bore size and rod diameter meets your other requirements. English to metric conversion: x(mm) = 25.4 x (length in inches) x(bar) = 6.9 x 10-2 x (pressure in psi) x(kn) = 4.4 x 10-3 x (force in lbf) x(lpm) = 3.8 x (flow in gpm) mm = millimeters lpm = liters per minute kn = kilonewtons psi = pound force per square inch lbf = pound force gpm = gallons per minute 1. Determine the retraction force: Retract force(kn) = Pressure(bar) x ( ) π x ((Bore diameter (mm)) 2 ( Rod diameter (mm)) 2 ) 40,000 2. Determine the extension force: Force(kN) = π x Pressure(bar) x (Bore diameter(mm)) 2 40,000 3. Determine the system pressure: Pressure(bar) = ( Force (kn) x 40,000 ) π x ( Bore diameter(mm) ) 2 4. Determine the extension cycle time: Ext cycle time(min) = π x Stroke(mm) x (Bore diameter(mm)) 2 4,000,000 x Cap flow(lpm) 5. Determine the cap end flow: Cap flow(lpm) = π x Stroke (mm) x ( Bore diameter(mm) ) 2 4,000,000 x Ext cycle time(min) 6. Determine the retraction cycle time: Retraction cycle time(min) = π x Stroke (mm) x (( Bore diameter(mm) ) 2 2 - ( Rod diameter(mm) ) ) 4,000,000 x Rod flow(lpm) 7. Determine the rod end flow: Rod flow(lpm) = π x Stroke (mm) x (( Bore diameter(mm) ) 2 - ( Rod diameter(mm) ) 2 4,000,000 x Retraction cycle time(min) ) 7
