Originally designed in the 1920's, the Ajax Pin and Bush Coupling is what gave the Westfield Division of Renold its start. Simple and virtually indestructible, the pin and bush design is ideal for applications that involve safety, such as elevator drives or fire pumps. The fail-safe aspect of the design allows the coupling to be serviced at convenient intervals, should the elastomer become damaged.
The elastomer elements reduce vibration and dampen impact loads, as well as accommodate misalignment up to 0.5 degrees. The original bushing is a neoprene elastomer with a graphite impregnated bronze sleeve. These are still available, as well as a contemporary version of this concept: urethane bushings.
Renold also manufactures many custom variations of this coupling including brake drum and shear pin type couplings.
