Publication date:   Feb 28, 1991

Scope

Establishes guidelines for measurement of dimensions, running accuracy and internal clearance of both radial and thrust rolling bearings. The purpose is to outline the fundamentals of various measuring and gauging principles which may be used in order to comply with the definitions of ISO 1132 and ISO 5593. The methods described in this Technical Report do differ amongst themselves and there are other adequate measuring and gauging methods. ISO/TR 9274 does not imply any obligation to apply any particular method. However, the methods specified may be referred to in cases of dispute.
