Precision Couplings

Precision Couplings - Description

More details

The Reliance range of shaft couplings is designed to provide reliable transfer of motion between two shafts. The range caters for parallel, angular and axial offset conditions. Bore sizes range from 1.5mm to 20mm and, most importantly, all Reliance couplings have to undertake a rigorous test programme that validates their performance. For critical applications test results can be provided if required, for technical assistance please contact us. A selected range is available from our online store. Please use our coupling selector if you are unable to find the component you require
