US Patent 10330143 Serviceable joint with removable race

A serviceable joint features a pin, a housing with a hollow interior, and a removable race. The race has hollow interior chambers, an upper one of which is larger than the lower. The bottom end of the pin is passable through the hollow interior chambers and onward through an open lower end of the housing to situate the top end of the joint pin within the upper chamber of the race, from which a remainder of the pin hangs in free floating state. A retaining ring is engaged in an annular groove in the peripheral wall of the housing to clamp the race in place in a seated position abutting a tapered exterior area of the race against a tapered interior portion of the housing, whereby the race is centered and stabilized in the housing to restrain the head of the free-floating pin.
