Quick Flex elastomeric couplings from R+L Hydraulics are now available in new configurations for tough environments.
Manufactured by R+L Hydraulics in Germany, the Quick Flex elastomeric couplings series from Lovejoy can be equipped with optional seals to keep out dirt and dust in contaminated or outdoor settings. Other variants include UltraTemp designs for continuous temperatures up to 177 °C and compact versions with shortened hubs for tight installation spaces.
Benefits of the range include low maintenance, fast elastomer changes, and no need for lubrication. This makes them ideal for applications where uptime is critical.
The benefits of Quick Flex Couplings
Quick Flex couplings are used in power transmission systems to protect surrounding components such as rolling bearings and to dampen vibration and shock loads. They are proven in demanding operations including steel and metal plants, kilns, crushers, mills, sawmills, and more.
The couplings require no oil or grease, which supports sustainability goals and reduces service complexity. “Checking the elastomer takes just minutes,” says Detlef Peick, Business Development Manager at R+L Hydraulics. “If it needs replacing, it’s a quick swap. Even if you delay replacement and the insert fails, the coupling protects itself – the hubs stay intact thanks to the non-contact design. That keeps downtime and costs low.”

Because the coupling avoids metal-to-metal contact, hub wear is minimal. In addition, the couplings are modular and available in multiple designs, sizes, and configurations. Engineers can mix and match housings, hubs, and elastomers – including versions with single or double flexible extensions – to fit their application. And if a standard combination does not meet requirements, R+L Hydraulics offers custom configurations, including options to integrate sensors, brake discs, or emergency drives.
Elastomer inserts are available in three hardness levels, with temperature resistance up to 177 °C, and are built to absorb misalignment and transmit high torques reliably.
The Quick Flex range covers torque ratings from 43 Nm to 902.5 kNm (continuous), up to 1800 kNm (peak). The couplings are available with bore sizes from 10 mm to 500 mm and with spacer options for shaft separations up to 3000 mm. Bore types include metric, imperial, keyed, tapered, and splined.
