Abstract
A pin for a bushing in a high wear, high abrasion, heavy loading joint is made with a manganese steel shroud forged into a groove in the center of a high strength alloy steel core. The shroud is heat-formed from a plate into a U-form which fits into the groove co-extensive with the area of wear. Grooves, or holes, for the retaining pins, or keepers, are formed in the high strength steel end portions of the pin.
