Claw Couplings

Claw couplings provide a compact, reliable solution for transmitting torque between shafts in demanding industrial environments. Their rugged design, combined with flexible inserts, allows them to handle shock loads, moderate misalignment and tough operating conditions with ease.

ACORN® offers a comprehensive range of claw couplings and spare inserts from leading manufacturers, with many popular sizes available from stock for fast delivery across the UK.

What are the benefits of claw couplings and where are they used?

Features and benefits of claw couplings

  • Claw couplings have a short overall length, meaning that they do not take up a large amount of space on the shaft. 
  • The elastic element dampens vibration and cushions shock loads, helping to extend the life of surrounding equipment. 
  • This coupling can compensate for angular, parallel and axial shaft misalignment.
  • The maintenance free design of claw couplings means that downtime and labour requirements are greatly reduced. 
  • This coupling is suitable for use in a wide range of applications, across many industries.  

Where are claw couplings used? 

  • Construction industry
  • Pumps
  • Compressors
  • Conveyors

Claw Couplings FAQs

What information do I need to select the correct claw coupling?

We’ll typically need: shaft diameters, required torque or kW and speed (rpm), type of driver and driven machine, expected misalignment, level of shock loading, and details of the operating environment (temperature, moisture, dust, chemicals). Our specialists can then recommend a suitable size and insert material.

Are different insert materials available?

Yes. Inserts are available in different elastomer hardnesses and materials to suit various torque ratings, temperature ranges and chemical exposures. Softer inserts typically offer better damping; harder inserts may increase torque capacity. Our couplings team can advise on the best option for your application.
