Features of  Precision Rotary Ball Screw/Spline

TBI motion rotatry ball screw and spline line is designed to enable the applcation to move linearly and rotationally in one assembly, with symmetrical orientation design between the outer and inner ball screw or spline nut. Both rotary and spiral movement can be achieved simultaneously.

TBI motion rotary line Is the most ideal key component in scara robots, industrial robots, pick & place, laser engraving, transporting and many other multi-directional application.


Zero clearance/High rigidity

TBI motion rotary line featured 40° angular (Back to back) contact angle within in the bearing. It enables self-aligning with minor mounting error and bears higher axial load to achieve better accuracy. Custom preload can be applied to reduce clearance and increase high rigidity. 

High speed/Smooth running performance

The rotary line uses TBI motion super lead screw to maintain high speed with smooth- ness in performance.

Noise reduction

The precision ground screw thread and spline groove make sure the ball bearing travel fluently during operations which reduce the skidding, friction and noise level and thus increase the service performance and life.

Plug and run/Compactness

TBI motion rotary line features a one-piece compact and easy mounting design.

Spline alternative

Ball spline offers customized end journal according to print. Hollow spline is availible on request for special operation environment in rentilation, piping on weight reduction.
