Why Choose ATRA-FLEX Flexible Shaft Couplings?

ATRA-FLEX flexible shaft couplings with elastomeric inserts are manufactured for the Power Transmission Industry and can cover wide variety of applications. They are designed to increase reliability and efficiency. ATRA-FLEX is the smart choice when operations are looking for standardization.

Couplings are available in many coupling styles and have the durability to face the challenges in the harshest of environments. Whether your operation requires standard sizing or needs quick delivery on a custom design, ATRA-FLEX has you covered. They require no lubrication and minimal maintenance. They are easy to install and take minutes to replace the polyurethane insert.

ATRA-FLEX couplings operate without any metal-to-metal contact therefore the elastomeric insert is the only spare part you’ll need. We offer a stainless-steel version for the food industry as well as a cost savings alternative to stainless steel called nitrocarburized that is corrosion resistant and will add lubricity increasing the life of the insert.
