PBSA Series


• High Positioning Accuracy
The Ball Spline groove profile is designed Gothic arch. By applied preload, the backlash in the rotational direction is eliminated therefore having higher positioning accuracy.

• Lightweight and Compact
Spline nut and the support bearing is integration structure. The Spline nut is designed lightweight. Therefore, the highly accurate and compact design is achieved.

• Simple Installation
The balls recirculation in ball holder, prevent balls falling from the spline nut while assembling.

• Support Bearing
The support bearing of the Ball Screw is designed a contact angle of 45°, thus it has higher axial rigidity, while Ball Spline has a contact angle of 45°, thus it has the average force of axial and radial direction.

• Smooth Motion and Lower Noise
As the Ball Screw is adapting end cap recirculation structure, thus can be smooth motion with lower noise.

• Applications
SCARA robot / Assembly robot / Automatic loader / and Machining center's, ATC equipment.
