A bonded rubber center damps vibration and allows high angular misalignment

3 products

Torque-Limiting Shear Couplings

When torque is too high, sever the connection between shafts so connected parts don't break

2 products

Electrically Isolating Servomotor Precision Disc Couplings

Block stray current so it doesn't erode or interfere with components on your shaft

1 product

Other Products

Rigid Shaft Couplings

Join two shafts that are aligned and handle higher torque than flexible shaft couplings

41 products

Shaft Adapters

Increase or reduce your shaft's diameter to fit equipment, or replace damaged shaft ends

18 products

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

77 products

Machinable Shaft Ends

Mill custom pulleys, threaded hubs, sprockets, collars, and sensor targets and mount them to shafts
