Made to meet strict military standards for material and construction, these stainless steel U-joints also balance strength with good corrosion resistance. Customize their bores until they fit your shafts. They come apart and have a small, centered starter hole on each end to make drilling easy. Because they’re single U-joints, they connect and transfer torque between two shafts that are misaligned at an angle. 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.

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.

U-joints with a ball-spring oil fitting keep lubricant in the joint.

Choose these U-joints for applications that run continuously in wet environments. Their needle bearings handle higher speeds and last longer than other types of joints. Made of stainless steel, they balance strength without sacrificing corrosion resistance. Since they’re single U-joints, they connect and transfer torque between two shafts that are misaligned at an angle.

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.

A good choice when you need accurate and repeatable motion, these U-joints have zero backlash (no play), so there’s no motion lost when your shafts change direction. This keeps machines running smoothly. They’re single U-joints, so they connect and transfer torque between shafts that are misaligned at an angle.

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.

Ball-bearing U-joints operate with less friction than pin-and-block joints, so they run at higher speeds. 303 stainless steel U-joints balance strength with good corrosion resistance.

U-joints that connect with set screws don’t require you to drill any holes. U-joints that connect with spring pins require you to drill holes through both the U-joint and your shafts. Spring pins are not included.

U-joints that don’t require lubrication are often used with optical devices and other sensitive equipment because they're less likely to attract dust and debris compared to lubricated U-joints. They’re also easier to maintain. Lubricated U-joints don’t require lubrication during installation.

To keep your shafts moving in sync, the flexible spring on these joints makes the output shaft move at the same rate as the input shaft. This spring also reduces vibration and compensates for more misalignment than standard single U-joints. However, these U-joints can’t handle as much torque. With zero backlash (no play), there’s no motion lost when you change direction. This keeps machines running smoothly with more accurate, repeatable motion. Made of stainless steel, these U-joints balance strength with good corrosion resistance.

A good choice for optical devices and other sensitive equipment, these U-joints don’t require lubrication or gather dust and debris. They’re also easier to maintain than lubricated U-joints. They work well in assemblies that change frequently because you can quickly loosen their clamping screw to move them. This screw holds these U-joints in place without damaging your shafts. 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.

Lengthen and shorten these telescoping U-joints to fit your application. They’re a good choice when you need accurate and repeatable motion because they have zero backlash (no play), so there’s no motion lost when your shafts change direction. This keeps machines running smoothly. 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 ball bearings, there’s less friction than pin-and-block joints, so they run at higher speeds. Made of stainless steel, they balance strength without sacrificing corrosion resistance.

Since they come lubricated, you won’t need to lubricate them during installation. 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.
