What are the features and benefits of backlash-free jaw couplings?

Dampening abilities

Backlash-free jaw couplings help to dampen vibration as well as reducing the impact of shock loads, protecting surrounding equipment from damage. 

Failsafe operation

These couplings are failsafe. This means that they will continue to operate should failure occur. 

Maintenance free

Backlash-free jaw couplings do not require lubrication or maintenance during operation, helping to reduce downtime and labour requirements. They are also easily to inspect visually, thanks to their split design. 

Able to transmit high torques

Despite their small dimensions, these couplings are able to transmit extremely high torques of up to 35,000 Nm.
