Universal Joints for Motion Control and Robotics

The precision you need to keep things in motion

Collage of robotics

Belden’s Needle Bearing Universal Joints can attain high angles and operate at a higher RPM than other u-joints, making them perfect for a variety of motion control and robotics applications. With near zero backlash and rigid axial stiffness for push & pull loads, the needle-bearing universal joint is manufactured to meet the highest industry standards for precision. Customization is Belden's specialty - hubs can be machined in alloy steel with a variety of platings, various grades of stainless steel, forgings and extruded aluminum for a high strength-to-weight ratio.
