High-Speed Single U-Joints
Often found in continuously running applications, these U-joints operate at higher speeds and last longer than other types of joints, thanks to their needle bearings. They’re single U-joints, so they connect and transfer torque between two shafts that are misaligned at an angle. Made of steel, they are strong and handle a good amount of torque.
These U-joints come lubricated, so you don't need to lubricate them during installation. To extend their life by keeping lubricant in and contaminants out, use the grooves on their body to add a cover (sometimes called bellows or boots). Drill holes through the U-joint and your shafts and then connect using spring pins.
Your shafts' misalignment will affect the speed and torque the U-joint will be able to transmit. The more the shafts are misaligned, the less speed and torque the U-joint will be able to transmit.
