THK - LBH - torque ball bushing

  • Compact torque bushing with a straight rectangular shoulder nut.
  • High torque capability
  • High speed and quiet
  • Long maintenance intervals

Product description

A rigid rectangular spindle nut does not require a housing and can be mounted directly on the machine body.

This results in a compact, very stable linear control system.

The spline shaft has three pairs of precision machined bearing tracks, 120º apart.

The ball lines are held in place and circulate through a ball holder inside the bushing.

This also holds the balls in place if the bushing should be pulled off the shaft.
