Magnetic force compensates for misalignment by transferring torque without wear or contact

2 products

Other Products

Rigid Shaft Couplings

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

27 products

Shaft Adapters

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

4 products

U-Joints

Transfer torque between shafts at an angle; handle more torque and misalignment than flexible shafts

23 products

Shaft Collars

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

58 products
