The TOCO Ball Screw Spline RN is a specialized component that integrates a ball screw (for linear motion) and a ball spline (for rotary motion) into a single unit. This is critical for applications requiring synchronized rotary and linear movement (e.g., screw driving, pressing, or transfer)

TOCO Ball Spline is a rolling guide element, mainly composed of a nut, a screw, a steel ball and a retainer. The steel ball rolls endlessly between the nut and the screw, allowing the nut to move linearly along the screw with high precision. The steel balls on the ball spline have an angular contact structure and can withstand radial loads and torque loads.

The ball spline is equipped with 3 sets of load-bearing balls, which are designed for face-to-face angular contact. The balls are held in a steel ball retainer to continuously perform a full-row cyclic motion. Through the optimized retainer design, high-speed, high-acceleration and deceleration guidance is achieved. In addition, the retainer's coating design for the steel ball ensures that the ball will not fall off when the nut is pulled out from the spline shaft.

TOCO's Ball Spline combines the best of ball screws and linear guides, delivering unmatched performance in demanding applications.

This innovative solution offers high rigidity and precision in a compact design, ideal for systems requiring both rotational and linear movement.Think aerospace components, high-end CNC machining centers, and other applications where precise, reliable motion is paramount.

This translates to reduced downtime and increased productivity for our customers.Choose TOCO's Ball Spline for unparalleled reliability and accuracy in your motion control systems.

Transmittable torque capacity
Compared with linear bearings, the steel balls in the rolling grooves are in angled contact, so the nut and the screw can move relative to each other to achieve the function of transmitting torque.

Integrated structure
The nut and bearing are integrated into one structure, achieving high precision and compact design.

Lubrication oil circuit
Through the optimized design of the oil circuit, the lubricating grease is directly guided to the ball return point, improving the lubrication effect and extending the service life.
