Couplings, Joints & Hubs

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. A mechanical joint is a section of a machine which is used to connect one or more mechanical part to another. Mechanical joints may be temporary or permanent, most types are designed to be disassembled. A hub is the central part of a circular object (such as a wheel or propeller)

Stock of couplings, joints and hubs from all major manufacturers. Express shipping available on most items. Easy 30-day returns.
