ATRA-FLEX Standard & HD Inserts

Easy Installation, Flexible Performance

ATRA-FLEX coupling inserts simplify machinery maintenance by being easy to install and replace, while accommodating

shaft misalignment and absorbing vibrations. Their durability and ease of install help protect machinery and expand its lifespan

reducing downtime and total cost of ownership.

 

 

When a new insert is needed, a low-cost replacement can be installed in minutes without moving either the prime mover or the driven equipment. Less downtime, no messy lubrication, no EPA regulations are some of the benefits to choosing ATRA-FLEX.  When inserts shear there is no metal-to-metal contact so there is no need to replace hubs.

 

Available on M-Series, T-Flex, and A-Series Couplings. These non-lubricated, quality elastomeric couplings provide excellent vibration-dampening capability, high-misalignment capacity, reduced maintenance costs and downtime, and designs for specific applications.

 

NEW – HD Inserts for T-Flex Series Couplings

Additionally, we designed an alternative insert for the T-Flex series using our same high-quality polyurethane that will allow certain applications to find that perfect fit by increasing your torque rating up to 30% before bumping up into the next size coupling or larger OD. This new design of HD Inserts will provide customers the opportunity to save on initial
coupling investment as well as long term insert replacement.
