Single row deep groove ball bearings are required to be BIS Certified according to IS 6455:2020. The Indian Standard has been developed to give the boundary dimensions, tolerances, and name system of single row deep groove ball bearings to be used in radial loads and, in some cases, radial and axial loads. The standard has the major dimensions, dimensional groupings, tolerance classes and accuracy specifications that guarantee similarity, exchangeability and predictable functioning in different industrial and automotive uses.
IS 6455:2020 focuses on dimensional accuracy and tolerance regulation to aid in correct fit in the shaft and housings and thus provide a smooth rotation with minimal friction and optimum load distribution. The specification provides uniformity in design parameters such that bearings produced by other manufacturers are compatible and can be useful across different operating conditions, such as high speed. It also dictates the requirements of marking, identification and verification of the dimensions to ensure traceability and compliance with the set standards.
The IS 6455:2020 certification of BIS ensures that manufacturers, OEMs, and end users that single row deep groove ball bearings meet nationally recognized standards with respect to dimensional accuracy, the reliability of their performance, and their suitability to operation. This standard is applied to help achieve safe and efficient use in electric motors, automotive, industry machinery and general engineering equipment where durability and precision are vital.
