Rod Alignment Couplers

Rod Alignment Couplers

Rod Alignment Couplers

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

Other Products

Shaft Couplings

Shaft Couplings

Connect two shafts to transfer rotary motion from one to the other

U-Joints

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

Shear Couplings

Shear Couplings

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

Torque Limiters

Torque Limiters

Keep torque at or below a set limit to control tension or braking or protect machinery from overload
