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

    Image of Product. Front orientation. U-Joints. Corrosion-Resistant Mil. Spec. Machinable-Bore Single U-Joints.
    Image of Attribute. Front orientation. Contains Annotated. 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. 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.
    Ball-Spring Oil Fitting—U-joints with a ball-spring oil fitting keep lubricant in the joint.

    Drill the bores to create custom U-joints that meet strict military standards for material and construction. These U-joints 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. Made of steel with hardened yoke ears for added strength and durability, they handle a good amount of torque.
    Drill holes through the U-joint and your shafts and then connect using spring pins. They have a ball-spring oil fitting to keep lubricant in the joint.
    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.
