Overview and included items
Our smooth-body uniball stem cup gives you a bearing mount for a boxed arm or a tube with a 1.50" inside diameter. The 1.50" OD mounting body has no locating ledge, so it is not tied to a particular tube outside diameter or wall thickness. We machine it from 4140 chromoly with a machined finish for a 7/8" WSSX or WPB series uniball bearing.
