Power transmission products transmit power to create motion. They are commonly used in industrial automation, material handling, and construction applications. Linear motion devices transmit power and support motion in a straight line. They include actuators and linear bearings. Rotary motion devices transmit power between rotating parts in a machine. They include chains, belts, pulleys, sheaves, and gears. Bearings extend the working life of wheels, pulleys, and other rotating parts by reducing friction and enabling parts to move smoothly.

Gearmotors consist of a motor, gear, and bearings in a housing and are commonly used in applications that require a high amount of force (torque) at low speed. DC gearmotors require a battery power source and are used for precise variable-speed applications such as wheelchairs, hospital beds, lifts and medical tables, power seats, and other automotive applications. AC gearmotors operate off an AC power source and are often used in high-power applications, such as lifts, jack, and robotics. Gearmotor accessories like brackets, covers, and extension cables are used to protect, mount, and power gearmotors.

Speed Reducers

Speed reducers are mechanical devices that help drive systems maintain optimal speed and torque for the application. Also known as gearboxes and gear drives, they lower the speed of rotation of the input shaft by a certain ratio and increase the power transmitted to the output shaft by the same ratio. Ratio multipliers increase the speed reduction and torque supplied by a speed reducer by a certain ratio and are suitable for parallel setups. Mounting bases, torque arms, and flange couplings are accessories used with speed reducers. They are often used in applications where the speed reducer will not be directly attached to the drive mechanism.

Power Transmission Belt

Power transmission belts, sometimes called drive belts, gear belts, or automotive belts, transmit power between two components, such as from a motor or driver to a drive shaft or pulley. Round belts are used on serpentine drives, line shaft conveyors, and commercial sewing machines. Connectors are used to connect two ends of a round belt that has been cut to size or needs to be installed without disassembling the drive system. Twisted O-rings are installed in V-belt and round belt pulleys and have a hook connector so they can be installed without dismantling the drive system. Variable-speed belts are used with variable-speed pulleys and accommodate changes in speed and pulley width as the drive systems speeds up and slows down. Belt accessories protect, maintain, and measure belt grooves and tension.


Shaft Couplings, Collars, and Universal Joints

Shaft couplings, collars, and universal joints are parts that connect equipment to transmit power and help protect against shock, vibration, misalignment, backlash, and overload. Jaw couplings, sleeve couplings, and tire couplings do not require lubrication and are commonly used on electric motor applications, such as gearboxes, conveyors, and medical equipment. Motion control couplings provide good rigidity in moderate- to high-torque applications like servomotors, robots, and machine tools. Oldham couplings maintain constant velocity with low bearing loads and are ideal for applications with high parallel misalignment. Rigid couplings allow minimal backlash between shafts of the same dimension and are suitable for continuous-motion applications. Shaft collars, adapters, and keyed shafts hold bearings, sprockets, and gears to shafts and other components and can act as mechanical stops. Universal joints transmit torque between rotating shafts that are at an angle to each other.
