1 Scope
GB/T 12613 in this section according to GB/T 27939-2011, provides for inspection of the inner diameter of the sleeve roll (GB/T 12613.2 of
Method C) requirements, and provides the necessary test methods and testing equipment.
Since the inner diameter of the sleeve is flexible in the free state, but after the installation because the outer diameter of the sleeve and the housing bore sizes interference fit, bushings
The maximum pore size adapted to the seat.
Note 1. Except otherwise specified and the specified unit, GB/T 12613 in this section All dimensions are in millimeters.
Note 2. Wrapped bushes - Dimensions and tolerances are given in GB/T 12613.1 in.
Note 3. The wall thickness of the test are given in 12613.7 in GB/T .
Note 4. Wrapped bushes outside diameter test given in GB/T 12613.5 in.
