High speed correspondence
   The SBN type return pipe is the ideal circulation method and doesn't have a lip so that the ball is picked up in a tangential direction and a flexible ball track can be held. The design, with enough strength in the return pipe and the ball cage,makes the use with DN value 130,000 possible.

Low noise
   The ball cage between balls eliminates collision noise. The return pipe does not have a lip so that the ball is picked up at a tangential direction and collision noise is eliminated. These devices result in low noise and high sound quality.

Long-term maintenance-free operation
   The ball cage acts as a lubricant reservoir. Adding the optional wire ring and the lubricator QZ ^* makes long-term maintanance-free operation possible even in adverse environments (foreign matter or coolant).

Excellent sliding
   The ball cege eliminates ball to ball friction of balls and improves the torque characteristics greatly.A pre-load dynamic torque fluctuation is reduced and it is possible to achieve excellent sliding.
