Bis Certification For Thin-walled Plain Bearings The Bureau of Indian Standards (BIS) has developed standards pertaining to thin-walled plain bearings under documents IS 10203:1982. These particular types of bearings are put in place in high- performance rotary machinery and combustion engines due to their efficiency in space constrained regions as well as the fact that they assist in reducing weight. The functioning characteristics of these bearings necessitate them to operate under speed and load conditions so as to provide sufficient smooth operation during varying levels of work. By adopting this standard, it is ensured by BIS that such components are made with exacting requirements regarding wall dimensions, surface finish, material properties, reliability and endurance. Any manufacturers wishing to sell these supports shall obtain certification from BIS which assures compliance with legally defined standards for quality and safety marking. Furthermore, all products bearing certification shall be marked with the ISI mark which claim adherence to requirements from BIS hence reinforcing consumer trust.
