ATRA-FLEX Millennium® couplings feature a detect and lock-on ring, internal support of insert for higher horse power and large bore capacity. ATRA-FLEX Millennium® couplings are also manufactured in the USA. Visit atra-flex.com to learn more about ATRA-FLEX Millennium®.

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 -60° to 250° Fahrenheit with high temperature inserts available up to 350°. 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. Stainless steels in grades 303, 304 and 316 are also available for corrosive environments and food applications.

ATRA-FLEX® offers numerous advantages, including faster change out of coupling inserts, custom compounded polyurethane inserts that provide elasticity and resistance to high torque, shear and shock loads. Plus, the elastic insert is highly resistant to humidity, oils, corrosion and chemicals while retaining performance characteristics at temperatures from 60°F to 250°F. No lubrication or service is required and ATRA-FLEX couplings offer 70,000 hours or more with no signs of wear. These couplings can be installed horizontally or vertically and can rotate in either direction with no metal-to-metal contact between coupling parts.
