Features
Easy Installation
Can be connected with the shaft by simply tightening a single bolt in each hub.
Compact
Using the clamping method, this series can reduce axial dimension, saving installation space.
Backlash-Free
All torque is transmitted by friction coupling to eliminate backlash. Perfect for high-precision positioning applications.
High Torsional Stiffness
The optimally designed disk based on finite element analysis boasts high torsional stiffness and excellent flexibility.
