Sleeve Auto Bearing Specification Example for Emergency Vehicles: Touring Version

This is a worked specification for sleeve auto bearing in a touring version 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 touring version version exists because the duty cycle on emergency vehicles is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.
