U-Joints

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

181 products

Shear Couplings

Sever the connection between shafts when there's too much torque to protect parts from breaking

21 products

Rod Alignment Couplers

Reduce wear on bearings and seals by flexing when the cylinder and load aren't precisely even

94 products
