Mechanical shaft-mounting components for transmitting motion between two shafts, locking or locating components, or as mechanical stops.
Couplings, Collars and Universal Joints Categories
Flexible Couplings (452 suppliers)
Flexible couplings connect rotating members while allowing some degree of angular or parallel misalignment.
Fluid Couplings (57 suppliers)
Fluid couplings are torque-transmitting couplings that use hydraulic oil or water to transmit power. They differ from torque converters in that the input torque is equal to the output torque (no multiplication of torque).
Rigid Couplings (221 suppliers)
Rigid couplings connect rotating members such as shafts. They secure onto both members and provide transmission of torque and motion.
Shaft Collars (148 suppliers)
Shaft collars attach to shafts and are used as stop features or targets for devices such as tachometers.
Shaft-Hub Locking Devices (87 suppliers)
Shaft-hub locking devices frictionally clamp gears, pulleys, flywheels, and other components to a shaft without the need for threads or keys.
Universal Joints (156 suppliers)
Universal joints are flexible mechanical connections used to transmit rotary motion from one shaft to another shaft that is not in line with the first, or when alignment varies during service.
