1、Classified by outer tube shape

Cylindrical: Compact design, suitable for scenarios where space is limited and rotation clearance needs to be controlled

Flange type:

Round flange type: fixed with bolts, easy to assemble, suitable for high-precision equipment such as CNC machine tools and robotic arms

Square flange type: Suitable for 3C and semiconductor equipment, with customizable sliced structure at the flange end

2、Classified by axial combination form

Integrated design: The spline shaft and nut are integrated, with a compact structure and high positioning accuracy

Rotating nut type: supports synchronous driving of rotational motion, suitable for composite scenarios of torque transmission and linear motion

3、Classified by shaft diameter and load capacity

Micro Ball Spline: Lightweight Design

Large shaft diameter ball spline: capable of carrying loads of several tons

1、High precision and stability

High repeat positioning accuracy, fully enclosed sealed structure reduces the impact of dust intrusion on accuracy;

Special contact angles，enhance torsional rigidity and reduce high-speed motion vibration.

2、Low friction and efficient transmission

The rolling friction coefficient is only 1/50-1/30 of that of sliding splines, with a transmission efficiency of over 95% and excellent temperature rise control;

Optimize the lubrication oil system, directly lubricate the ball return area, and extend the maintenance cycle.

3、Multi directional load capacity

It can simultaneously withstand radial force (cantilever load), axial thrust, and torque, with a maximum radial load of several tons;

Pre pressure adjustable design enhances impact resistance.

4、High speed adaptability

Supports rotation speed>3000rpm and linear speed ≥ 5m/s, meeting the requirements of laser cutting machines and high-speed sorting equipment;

The low inertia characteristic shortens the start stop response time and has better acceleration performance than traditional sliding mechanisms.
