R+L Hydraulics has released the Quick Flex HighTemp series, a robust, low-maintenance coupling solution for applications operating at temperatures up to 177 °C
Manufactured and distributed by R+L Hydraulics in Werdohl, Germany, Quick Flex HighTemp extends the advantages of elastomeric couplings into demanding environments near industrial furnaces, superheated steam systems, steam turbines, and steel and metals processing plants.
The coupling design uses opposing, non-interlocking teeth with a central elastomer insert. This prevents metal-to-metal contact between the coupling components and reduces wear on the hubs. As the coupling requires neither oil nor grease lubrication, routine oil checks and relubrication are not necessary.
This low-maintenance design suits high-temperature applications, where maintenance access may require extended cooling periods. Operators can quickly replace the elastomer insert, reducing maintenance time and restoring machine availability sooner.
The HighTemp configuration uses a white, heat-resistant elastomer insert that provides high damping while accommodating shaft misalignment. Depending on the coupling configuration, nominal torque ratings range from 93Nm to 601.5kNm, with momentary torque peaks of up to 1,200kNm.
Flexibility surpasses temperature and torque, with bore diameters ranging from 10mm to 500mm in the Quick Flex range. Spacer configurations accommodate shaft separations from 25mm to 3,000mm, while shortened hubs support applications with limited installation space.
The modular design lets engineers and plant operators combine hubs, covers, and elastomer inserts to meet application requirements. Hubs can also be modified to integrate components such as brakes, auxiliary drives and sensors. This configuration flexibility enables customers to match the coupling more closely to their equipment while drawing on a common product platform.
