Lightweight
The Model LTR-V is more lightweight than the previous Model LTR-A because it uses a Model LT-X for the ball spline.
High Rigidity
The support bearing uses a 45° contact angle that is resistant to moment loads.
Linear and rotary mechanisms
Ball splines can transmit torque with one shaft, enabling operations that combine linear motion and rotation.
