T/HNMES 08-2024 The measurement method for the radial clearance of a three-point contact ball bearing
Basic Information
Scope
Main technical content: This standard describes the measurement methods of radial clearance for three-point contact ball bearings with inner and outer rings of integral structure, double-half inner rings, and double-half outer rings, applicable to the measurement of radial clearance for three-point contact ball bearings with an inner diameter of 10 mm to 350 mm (hereinafter referred to as bearings). The main content of this standard includes scope, normative reference documents, terms and definitions, principles, test conditions, instruments and equipment, test steps, test data processing, and test reports. This standard is applicable to guiding the production units, users, and third-party inspection service units of three-point contact ball bearings in the detection of radial clearance for such bearings. This standard is based on the perspective of the entire bearing industry. In view of the problem that there are no unified national and industry standards for the measurement method of radial clearance for three-point contact ball bearings, which affects the consistency of product performance, this standard clearly specifies the measurement method and related requirements for the radial clearance of three-point contact ball bearings, providing a standardized and unified technical support for the production and application of such bearings in the bearing industry.
