Key Features

  • With Model LT or Medium Torque Type Ball Spline, the spline shaft has two to three crests on the circumference, and along both sides of each crest, two rows of balls are arranged to hold the crest so that a reasonable preload is applied.
  • This model has a large load capacity in the radial and torque directions. Since the contact angle is large and an appropriate preload is given, high rigidity against torque is achieved.
  • The rows of balls are held in a special resin retainer incorporated in the spline nut so that they smoothly roll and circulate. With this design, balls will not fall even in the nut is removed from the spline shaft.

Product Description

The Ball Spline is an innovative linear motion system in which balls accommodated in the spline nut transmit torque while linearly moving on precision-ground raceways on the spline shaft. Unlike the conventional structure, a single spline nut can provide a preload with THK's Ball Spline. As a result, the Ball Spline demonstrates high performance in environments subject to vibrations and impact loads, locations where a high level of positioning accuracy is required or areas where high-speed kinetic performance is required. The Ball Spline provides a high degree of safety and long service life.
