Product Description
The outer diameter of the ball spline bearing sleeve is cylindrical. When the torque is transmitted, the key is used after the key is knocked in, which is the smallest installation space.
Product Feature
1 Large Load Capacity
Every groove of the shaft is precision ground to form a 30° angular contact points. Thus, this model has large load capacities in the radial and torque directions
2 No Angular Backlash
At a contact angle of 30° to provide a preload in an angular-contact structure. This eliminates an angular backlash in the rotational direction and increases the rigidity.
3 High Rigidity
Due to large contact angle, it can give proper preload subject to availability. Thus, it can get high rigidity and large moment.
4 Ball Retaining Type
With ball holder, prevent balls falling from the spline nut while assembling.
5 Application
Robots, Transporting equipment, Wire winder, ATC (auto tools change)…etc.
Design Principle
The ball spline has load groove of three row on the outside diameter of shaft. Due to the Gothic arch groove design, it could be make sure three grooves withstand clockwise or Counterclockwise of torque at the same time, and then increase the service life and rigidity.
The balls recirculation in ball holder, prevent balls falling from the spline nut while assembling.
