Elastic jaw couplings for hydraulics applications


R+L Hydraulics presents Spidex couplings for hydraulics applications. These elastic jaw couplings are axially mountable, fail-safe and maintenance free. They stand out particularly because of their vibration damping properties. Typical applications include pumps and compressors, agricultural and construction machines as well as wind turbines.

Elastic jaw couplings dampen mild torque spikes by temporarily absorbing some of the energy. This reduces deviations in the transmission of torque and power. The design reduces body resonance during operation while suppressing any arising noises. Torque is transmitted in a fail-safe, positive engagement. Depending on the customers’ requirements, the couplings are made of steel, aluminium, grey cast iron or sintered steel. The convex profiled spider consists of a thermoplastic polyurethane elastomer and is exclusively pressure loaded. It absorbs any radial and angular misalignment of the two connected shafts. Spider materials excel due to their high resistance to wear and tear, elasticity, good dampening properties and resistance to oils, greases, solvents, atmospheric effects and ozone. As standard, the spider has a hardness of 92° Shore A. For higher torques a hub of 95° or 98° Shore A can be used. Operating temperatures of the couplings range from -40 °C to +100 °C. Short-term temperature peaks of up to +120 °C are admissible.

Spidex couplings are available in various designs, with bore sizes from 6 mm to 145 mm. Known to users under the Raja brand, these couplings are designed and produced in the plant in Werdohl, Germany. R+L Hydraulics continuously invests in research and development as well as quality assurance. Flexible production, effective warehousing and logistics processes result in quick terms for turnaround and delivery. In addition to couplings for hydraulics and power transmission, R+L Hydraulics develops and produces a broad range of hydraulic accessories under the Raja brand, including oil-water heat exchangers, oil-air heat exchangers, shell-and-tube heat exchangers, plate heat exchangers, cooling systems, rigid and noise-damped bell housings, dampening elements, coolant pump bell housings and aluminium tanks.
