Connect and transfer torque between two shafts that are misaligned at an angle. Your shafts’ misalignment will affect the speed and torque these U-joints will be able to transmit. The more the shafts are misaligned, the less speed and torque they’ll be able to transmit.
Pin-and-Block Joint—Pin-and-block U-joints handle higher torque at lower speeds than other joint types such as those with needle bearings, making them a good choice for most applications. 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).
Steel—Steel U-joints are strong and handle more torque than zinc alloy U-joints.
For Keyed Shafts—U-joints for keyed shafts connect to shafts with set screws. Unlike U-joints that use spring pins, there’s no drilling required.
