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 not fall off if the LM block is removed from the rail (except for types HSR 8, 10, and 12). The four trains of balls are arranged so that the contact angle is 45°, allowing each train of balls to bear an equal rated load in all four directions: radial, reverse-radial, and the two lateral directions. This type can therefore be used in any installation direction. Moreover, HSR enables the application of a well-balanced preload, making it possible to increase rigidity in the four directions while maintaining a low friction coefficient. The low-profile design and use of high-rigidity LM blocks provide stable, highly accurate linear motion.
