Uniquely combines the stability of a compression type coupling with the safety of a shear coupling. In the event of a lockup, the insert will shear, minimizing the possibility of damaging your rotational equipment. No lubrication or routine maintenance is required.

The rugged polyurethane insert is the only spare part and can be replaced in minutes without having to move the equipment or the shaft hubs. Standard inserts have a temperature range from -51° to 121° Celsius with high temperature inserts available up to 177°. The inserts are available in a range of hardness to meet most torsional stiffness and torque requirements, and offers very high resistance to chemicals and weather.

ATRA-Flex® Couplings are manufactured in the USA. Standard hubs and rings are machined from solid carbon steel rounds and tubing, maintaining tight tolerances which provides excellent coupling balance.

A complete coupling is 2x hubs, 1 x insert, 1 x ring. This product is for the Hub, see related products for the insert and ring.
