Single U-Joints

Connect and transfer torque between two shafts that are misaligned at an angle.

Corrosion-Resistant Single U-Joints

Use these U-joints in wet environments to connect and transfer torque between two shafts.

High-Torque Single U-Joints

With a maximum torque of at least 11,600 in.-lbs., these U-joints handle more torque than any other U-joint in our offering.

Corrosion-Resistant High-Speed Single U-Joints

Choose these U-joints for applications that run continuously in wet environments.

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.

Sealed Single U-Joints

A cover (also known as a boot or bellows) seals out contaminants and seals in lubricant.

Corrosion-Resistant Sealed Single U-Joints

Ideal for wet environments, these U-Joints are stainless steel, so they have good corrosion resistance while also balancing strength. They have a heat- and water-resistant silicone cover (also known as a boot or bellows) to keep lubricant in and contaminants out.

Sanitary Sealed Single U-Joints

Often found in food, cosmetic, and pharmaceutical plants, these U-joints connect misaligned shafts in sanitary environments.

Mil. Spec. Machinable-Bore Single U-Joints

Drill the bores to create custom U-joints that meet strict military standards for material and construction.

Corrosion-Resistant Mil. Spec.
Machinable-Bore Single U-Joints

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.

Machinable-Bore Single U-Joints

Customize the bores of these U-joints to fit the exact dimensions of your shafts.

Precision Single U-Joints

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.

Constant-Velocity Single U-Joints

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.

Extreme-Angle Geared Single U-Joints

The gears on these U-joints transmit rotary motion between shafts that are misaligned at angles up to 136°, the widest angle of all our U-joints.

Clamp-On Single U-Joints

Ideal for use in assemblies that change frequently, these U-joints have clamping screws that can be quickly loosened when you need to move them.

Double U-Joints

Adjustable-Length Precision Double U-Joints

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 the shafts change direction.

Precision Double U-Joints

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.
