Since the wall thickness of the bush is measured in the free condition, no special test data are required for this on the drawing (see ISO 3547‑5 and ISO 3547‑6).
NOTE Depending on the manufacturing method, the back of the bushes can show isolated light depressions and, similarly, bushes with lubrication holes, grooves and bore indentations can show distortion. It is therefore suggested to measure the wall thickness away from these areas.
