    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. They’re single U-joints, meaning they connect and transfer torque between shafts that are misaligned at an angle. Often found in continuously running applications, they operate at higher speeds and last longer than other types of joints, thanks to their needle bearings.
    Connect these U-joints to shafts using the included set screws. Unlike U-joints that use spring pins, there’s no drilling required. All have a grease fitting, so you can use a grease gun to lubricate all of the bearings at once.
    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.
    Steel—Steel U-joints are stronger and handle more torque than iron U-joints.

    A cover (also known as a boot or bellows) seals out contaminants and seals in lubricant. These U-joints come lubricated, so you don’t need to lubricate them during installation. They're single U-joints, which means they connect and transfer torque between two shafts that are misaligned at an angle. A good choice for operations that run continuously, they operate at higher speeds and last longer than other types of joints, thanks to their needle bearings. Made of steel, they are strong and handle a good amount of torque.
    Connect these U-joints 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.

    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.

    Often found in food, cosmetic, and pharmaceutical plants, these U-joints connect misaligned shafts in sanitary environments. Their stainless steel body won't corrode from frequent washdowns with harsh chemicals and is highly polished, so there's no crevices for bacteria to grow. Their lubricant is NSF registered H1 for incidental contact with food. A heat- and water-resistant silicone cover (sometimes called a boot or bellows) seals this lubricant in and keeps out contaminants.
    They’re single U-joints, so they connect and transfer torque between two shafts that are misaligned at an angle. A good choice for applications that run continuously, they operate at higher speeds and last longer than other types of joints, thanks to their needle bearings. Since they come lubricated, 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.
    FDA Compliant 21 CFR 177.2600—FDA-compliant U-joints have a cover that is safe for direct contact with food.
