Sleeve Auto Bearing Specification Example for Assembly Programmes: OEM Replacement

This is a worked specification for sleeve auto bearing in a oem replacement programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The oem replacement version exists because the duty cycle on assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
