Pin Bush Couplings

Pin bush couplings 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.
