Connect and transfer torque between two shafts that are either parallel to each other or are misaligned at an angle. When shafts are parallel, these double U-joints keep them moving in sync by making the output shaft move at the same rate as the input shaft. They have a pin-and-block joint, so they handle higher torque at lower speeds than other joint types, making them a good choice for most applications. Made of steel, they are strong and withstand a good amount of torque.

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.

Since these U-joints have zero backlash (no play), there’s no motion lost when your shafts change direction, so machines move smoothly with more accurate, repeatable motion. As double U-joints, they connect and transfer torque between two shafts that are either parallel to each other or are misaligned at an angle. They also keep parallel shafts moving in sync by making the output shaft move at the same rate as the input shaft. And because their ball bearings operate with less friction than pin-and-block joints, they run at higher speeds. Made of stainless steel, these U-joints balance strength with good corrosion resistance.

They come lubricated, so you won’t need to lubricate them during installation. Connect them to shafts using the included set screws. Unlike U-joints that use spring pins, there’s no drilling required.

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.

A spring automatically lengthens or shortens these U-joints to fit your application, making them a good choice for assemblies with frequent changes. And since they connect to shafts using the included set screws, there’s no drilling required, unlike U-joints that use spring pins. As double U-joints, they connect and transfer torque between two shafts that are either parallel to each other or are misaligned at an angle. They also keep parallel shafts moving in sync by making the output shaft move at the same rate as the input shaft. With a pin-and-block joint, they handle higher torque at lower speeds than other joint types, making them a good choice for most applications. Made of steel, they’re strong and withstand a good amount of torque.

Drill custom bore sizes to connect shafts that are either parallel to each other or are misaligned at an angle. These double U-joints come apart and have a small, centered hole on each end to make drilling easy. Besides transferring torque, they keep parallel shafts moving in sync by making the output shaft move at the same rate as the input shaft. They have a pin-and-block joint, so they handle higher torque at lower speeds than other joint types such as those with needle bearings, making them a good choice for most applications. Made of steel, they’re strong and handle a good amount of torque.

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.
