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.
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
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.
High Rigidity Due to large contact angle, it can give proper preload subject to availability. Thus, it can get high rigidity and large moment.
Ball Retaining Type With ball holder, prevent balls falling from the spline nut while assembling.
Application Robots, Transporting equipment, Wire winder, ACT (auto tools change)…etc.
