Universal Joints Replacement

Universal Joints

The Uni Joint or U joints has been an industry standard for over 115 years, for engineers looking for a flexible power transmission coupling solution for high speed minimal misalignment applications. The Spicer Universal joint was first patented in 1904.

The standard uni joint is made up of 3 components, 2 end yokes and the universal joint itself.

Universal Joint – The U-joint contains 4 small bearings at the end of each of the cross, these bearings need to be maintained and kept lubricated or they will heat up and seize, requiring replacement meaning time and money, add to that the universal joint design which allows the two attached shafts to work out of alignment.

This misalignment means the ball bearings inside the bearing cross will wear against the outside of the race (groove the ball bearings sit in) leading to the race being enlarged and the ball bearings becoming loose, leading to increase vibration potentially damaging attached equipment or bearing failure.

Universal Joints are usually broken up into 2 types, automotive (includes agriculture heavy duty versions) and industrial. The main difference being is the industrial universal joints usually have a smaller angle of misalignment meaning they run faster, longer, where the automotive is more HP more misalignment but shorter usage time)

Automotive OEM and aftermarket include Spicer, Moog, SKF, Neapco, Weasler , and Industrial universal joints are made by Lovejoy, Belden, Ruland and others.

Yokes

The Yokes allow the two shafts (input/output) to attach to the universal joint. These yokes vary and some have to be welded on to the shaft. The yokes are substantial in size except where they attach to the universal joint, they are only slightly larger to ensure the joint can work at an angle without binding or hitting the propeller joint.

Yokes allow for a smooth transfer of power from input to output
