Pin Bush Couplings are mechanical devices designed to connect two shafts and transmit torque between them. They consist of a series of pins and bushes, where the pins are made of metal, and the bushes are typically crafted from elastic materials such as rubber or synthetic polymers. This unique combination allows the coupling to absorb shocks, dampen vibrations, and accommodate slight... https://www.anantengineering.com/blog/pin-bush-couplings-the-backbone-of-efficient-machinery-performance.htm
