This International Standard specifies the selective assembly of bearings (in accordance with ISO 3548).
The bearing diametral clearance is determined by the housing diameter, journal diameter and the wall thickness of the two half bearings. Typically, these components will have a total tolerance “stack up” of 50 μm to 60 μm. Current engine development and in particular, the desire for improved engine refinement, have suggested that the clearance range due to the tolerance “stack up” must be decreased. This International Standard suggests various schemes of selective assembly to achieve such ranges.
