R&D Flexible Coupling 910-029

R & D Marine 910-029 Flexible Coupling

For 5" Flange Borg Warner, ZF Hurth, Volvo & PRM Gearboxes

R & D Marine has developed a wide range of competitively priced Flexible Couplings to fit all major installations. The R & D Flexible Couplings reduce engine noise, vibration transmission and are designed to accept propeller thrust, a separate thrust bearing and bulkhead are not required. The couplings are made from a polyester elastomer which is not affected by salt water, diesel and lubrication fluids. If electrical continuity is required an earthing connector can be fitted in the centre of most Flexible Couplings. Installation is quick and easy as the R & D Coupling requires no machining and comes supplied with bolts to connect between the two existing shaft flanges. Checking alignment on installation and during service checks is quick and easy using the red cone headed bolt
