2. Quiet Operation
Metal-to-metal contact between the balls is eliminated by the ball
cage resulting in a quiet operation.
4. Long-term Maintenance-free Operation
Grease pockets are provided consecutively over the entire ball circulating path to constantly lubricate the
balls enabling long-term maintenance-free operation.
3. Orderly Ball Movement
Since the balls are held by the ball cage in the form of a
belt, they are uniformly distributed along the raceways of
the block. There is no skewing of the balls and no sudden
variations in friction, which results in stable movement.
