SR-TB Type (Heavy Load Type)

The SR's balls roll in four rows of a precisely-ground raceway on an LM block and LM rail. The end plate attached to the LM block causes the train of balls to circulate. As the balls are held in place by the retainer plate, they won't fall out 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. Due to its low-profile and compact design and the 90° ball contact angle in the radial direction, the SR is best suited for horizontal guideways.
