    Single Universal Joints, Friction Bearing

    Single friction bearing universal joints are best suited for space constrained applications with angular misalignment up to 45°, almost double that of commodity style u-joints. They are comprised of two yokes and one block that are joined by pins which are all precision machined and ground to ensure tight tolerances allowing for consistently smooth operation with minimal backlash. Single universal joints have higher torque capacity than equivalently sized double universal joints. They are available in steel for high torque and stainless steel for increased corrosion resistance. Straight and step bore sizes including inch to metric are available from 3/16” to 1-1/2” and 5mm to 35mm. Single universal joints can be combined with a boot to protect the joint from contaminants in the operating environment. The boot can be packed with grease for infinite life, reducing maintenance on the universal joint leading to more machine uptime.
