Rigid shaft coupling
When the application requires a direct and solid shaft connection and that shaft misalignments during operation are minimal, then the solid or rigid type couplings can be used. We offer a number of rigid coupling designs.
Type HR rigid coupling
Two distinct designs are available. The one and two piece HR series couplers have superior holding power and maintain alignment. The single piece versions are supplied with four clamping screws. The two piece split version couplers can be installed and removed without machine dis-assembly. Supplied with eight clamping screws, they provide reliable holding power and maintain alignment. The HR series suits shaft sizes from 6mm up to 50mm in diameter.

Precision Solid Couplings
Rigid couplings are available as standard in aluminium alloy and stainless steel. For smaller shaft sizes the new SC series clamping method that ensures the concentricity of the clamped shaft. Suited to shaft sizes from 3mm to 15mm, including imperial and custom formats, make the new SC series ideal for applications where high torque and exceptional torsional stiffness are required.
- Exceptional torsional stiffness
- High torque capacity
- Metric and Imperial bore formats
- Integral clamp shaft attachment
