The end plate attached to the LM block causes the trains of balls to circulate. As the balls are held in place by the retainer plate, they do Compact and heavyloadbearing Due to its lowprofile, compact design and the 9 ball contact angle in respect to the radial direction, LM Guide SR is best suited for horizontal guideways. Simple establishment of mounting accuracy A selfadjusting type capable of compensating for errors in parallelism between two axes and levelness, SR ensures precision and smooth, lively linear motion. not fall off if the LM block is removed from the rail. The low profile of the assembly and the high rigidity of the LM block combine to provide stable linear motion with a high degree of accuracy. High durability Free from differential slip even under preload or uneven load, the balls roll smoothly. This results in high wear resistance and excellent longterm precision. Stainless steel type available Upon request, we can provide stainless steel LM blocks, rails, and balls. Low noise The guideway on the end plate installed at each end of the LM block ensures the smooth circulation of the trains of balls at turning corners. As a result, the rolling balls generate little noise. A14

www.thk.ru BERG AB thk@thk.ru Тел. (49)2222, ф. (49)221 Characteristics of Type SR Compared with a guide with a 4 contact design, type SR features the superior characteristics specified below. By taking advantage of those characteristics, we can produce machines and equipment of higher precision and rigidity. Differences in Load Rating and Service Life Type SR is constructed so as to provide a 9 ballcontact angle. Compared with a 4 contact angle, use of a 9 contact angle results in a different load rating and service life. Compared with products of the same ball diameter, under the same radial load specified below, with type SR the balls are subjected to only % of the load they receive with the 4 contact design. As a result of this difference, the service life is nearly doubled. Contact design of type SR Ball diameter and nominal service life (when number of balls Z = 24) Contact design of type HSR 9 contact design Nominal service life 4 contact design Ball diameter Ball Diameter and Nominal Service Life Fig. 2 Difference in Accuracy Machining (grinding) errors that occur in an LM rail or block affect running accuracy. A grinding error ³ on a raceway results in an error in the radial direction 1.4 times greater in the 4 contact design than in type SR, which features a 9 contact design. In the horizontal direction as well, the error with the 4 design is 1.22 times that with the contact design.

www.thk.ru BERG AB thk@thk.ru Тел. (49)2222, ф. (49)221 Difference in Rigidity The 9 contact design applied to type SR differs in rigidity from the 4 design. Under the same radial load P, the deflection in the radial direction with type SR is only % of that with the 4 design. The diagrams below show the differences in radial load and deflection. Therefore, when it is necessary to ensure rigidity in the radial direction, type SR has an advantage over other types. AIV Deflection Deflection in the radial direction Deflection Deflection in the radial direction Fig. 4 Deflection under Radial Load Load and deflection (Da =. mm) for different contact angles (Deflection per ball) Contact angle: 4 Deflection Contact angle: 9 Applied load (N) Fig. Radial Load and Deflection Summary As illustrated above, type SR is best suited for places where the radial load is the main load, radial rigidity is required, and it is necessary to ensure running accuracy in both the horizontal and vertical directions. However, where a large reverseradial or lateral load or a great moment is exerted, we recommend use of a fourway equalload type such as HSR. A1

As a result, type DS does not protrude over the top surface of an LM block. The expansion ratio is equal to or greater than that of a conventional bellows. 2. Each ridge of the bellows has a partition plate to prevent the bellows from lifting. As a result, type DS can be used in the vertical, wallhung, and tilted positions.. Excellent highspeed operation, up to as high as m/min. 4.
