Ball Splines

This units combination of a conventional ball spline and rotary function dramatically contributes to eliminate parts used in your systems, and thence, accumulating minor errors that are often seen due to installation process can be diminished as well. Read more...

The Isotech Ball Spline is designed for mechanical applications which require both linear motion and torque transmission. The rolling contact of the balls eliminates backlash and reduces friction, helping you to achieve super precision and reliability. Read more...

Interchangeable cylindrial ball spline nut. LT-X nut is more compact than the conventional ball spline nut, Model LT. Outer diameter is up to 10% smaller. This product is compatible with LM bushings.

NB ball splines are used in a wide range of applications, including robotics, transport-type equipment and other machinery where it is necessary to sustain heavy loads while transferring torque smoothly. Several models are available, including various nut and shaft configurations.

Key Features At-a-Glance

NB ball splines are comprised of a shaft and nut assembly. Ball splin... Read more...

The LFK-X/LFH-X type Ball Spline helps save space due to its compact outer dimensions and light weight. This allows for more compact mounting and peripheral components.

The models LFK-X and LFH-X are designed with a lower core height than the conventional model LF-X. This enables more compact designs and space-saving connections of peripheral components.

Ball Screw Spline SPBR/SPBF

One single axis makes positioning, linear and rotary motion all possible!

The NB Ball Screw Spline consists of a high accuracy, high rigidity Ball Screw nut and Ball Spline nut attached to the ball screw spline shaft which has a screw groove and spline grooves. SPBR type has a Rotary Ball Screw nut and Rotary Ball Spline nut. Rotary Ball Screw nu... Read more...

The NB ROTARY BALL SPLINE can be used for both rotational motion and linear motion. The applications include SCARA robots, the vertical shaft of assembly equipment, tool changers, and loaders, etc. Read more...

The NB ball spline SSP-AM type has a smaller spline-nut diameter compared to the conventional SSP type nut on the same shaft diameter. The SSP-AM type is best suited for chip-mounter head devices and multiaxial applications.
Anti-corrosion type is also available. Read more...

The NB ROTARY BALL SPLINE combines a spline nut and a set of angular contact bearings in a compact, precise, and high-speed rotation-capable assembly, providing linear and rotational motion simultaneously. Read more...
