High-Speed DN value 160,000
   Sinse SBK's circulating machanism (end cap) is capable of picking up balls in the tangential direction, it allows natural ball motion and makes itself an ideal circulation method. The design , with enough strength in the end cap and ball cage,makes the use with DN value 160,000 possible.

Smooth mation
   The use of ball cage eliminates ball-to-ball friction, and allows the balls to be evenly spaced and circulate,reducing the fluctuation in dynamic torque,thus to achieve smooth motion.

Long-term maintenance-free operation
   The use of ball cage allows grease pockets to be maintained throughout the whole circulating area and a lubricant to be retained, achieving long-term maintenance-free operation.

Low noise and an acceptable running sound
   The use of a ball cage eliminates collision noise. The circulating mechanism, capable of picking up balls in the tangential direction, also contributes to eliminating collision noise.Thus, SBK runs with an acceptable sound and low noise emission.
