Description
TSUBAKI EPR — Power Rigid Coupling, genuine TSUBAKI product.
Overview
The Tsubaki Power Rigid Coupling joins two shafts in precise, rigid alignment using a clamping design, transmitting torque with no backlash and no flexibility. It is used where shafts are accurately aligned and torsional stiffness is a priority, such as connecting drive shafts in line or linking ball screws and precision axes.
Key Features
- Rigid connection with no backlash
- Clamping design for keyless shaft fixing
- High torsional stiffness
- Bore combinations for different shaft sizes
