High speeds can be problematic for joints fitted with plain friction bearings, even if the transmitted torque is low.
Needle-Bearing universal joints are equipped with roller bearings that reduce friction. These high-precision joints are built with rigid axial stiffness that maintain minimal backlash at higher angles for critical applications, such as robotics and instrumentation. They deliver superior lifetime at continuous operations and high RPM and operating angles of up to 45°. They have the capability to be rebuilt when wear and tear occurs – a Belden exclusive.
- Boot covers are recommended in gaseous and abrasive environments for added protection of the cross and bearings.
- Minimizes and maintains near-zero torsional backlash
- Superior lifetime at continuous applications and high RPM (up to 6000)
- Operating angle up to 90° (45° per joint)
- Needle bearings lubricated for lifetime of the joint
- Yoke material: fatigue-proof steel or stainless steel
- Cross material: high-grade alloy steel, hardened and precision ground
- Hub ends available with several standard bore configurations (plain bore, keyway, hex- and square bore)
- Optionally available Platings: Zink, Nickel, Cadmium, MoS2, Black Oxide
- Pin & block design with needle bearings available as well
- Telescoping Drive Shaft also available upon request.
Cross-Type Needle Bearing Customization
Universal joints can be customized by bores, keyways, special hub configurations. They can be manufactured from a wide variety materials and finished with specialty coatings and platings. Components can be outfitted with lubricant retaining boots, containing specialty lubricants for a variety of industries and applications.
