Single U-Joint, 12 mm x 7/16" Bores, 1.245" (31.6 mm) OD, Steel

This Ruland single friction bearing universal joint has 12mm x 0.4375" bores, a 1.245" (31.6mm) outer diameter, and a 3.750" (95.3mm) length. It is best suited for applications requiring a short length and high torque (when compared to double universal joints of an equivalent OD). This single universal joint is made of a block, two pins, and two yokes. These components are manufactured to tight tolerances using proprietary processes that ensure smooth operation and high misalignment accommodation up to 45°, which is a significant improvement over commodity style single universal joints. It is made from high grade alloy steel for high torque capabilities. The user can add a boot to protect the joint from unwanted contaminants and increase service life. This single friction bearing universal joint is manufactured in the USA.
