BIS CERTIFICATION FOR POROUS METAL POWDER OIL IMPREGNATED BEARINGS IS 3980

Published Date: Oct 10, 2025 4 min Read

BIS Certification is mandatory for Porous Metal Powder Oil Impregnated Bearings under IS 3980:1982. These special bearings are now widely applied in machinery, vehicles, home electrical appliances, sports, gymnastic apparatus and so on because of its self-lubrication property. Unlike other bearings that need regular external lubrication, porous oil-containing bearing absorbs and stores the discharged oil in its structure which is released for use, contributing to smooth operation and long-lasting life. As bearings are an important factor in reducing friction and wear in moving parts, certification of their quality, reliability and safety is essential.

IS 3980:1982 – Porous Metal Powder Oil Impregnated Bearings

This Indian Standard specifies requirements, dimensions and performance of powder metallurgical metal powder porous oil bearings. Bearings are made from sintered metallic powders, usually bronze or iron alloyed with carbon and graphite, the porosity of which is controlled to permit oil impregnation. Hot-oil lubrication then causes the oil to flow to the bearing surface in use, with low friction and wear and a minimum of noise. The standard prescribes basic requirements such as moisture content, porosity, oil content, physical strength and dimensional accuracy. It also establishes test methods (carrying capacity, life, and capacity to retain oil) that describe ways of determining have been found to be reproducible. In addition, IS 3980:1982 imposes conditions for marking, packaging and sampling to trace history and performance. By meeting this criterion, manufacturers ensure that their products are consistent and safe for longer industrial use.

Benefits of BIS Certification for Hand Operated Gearless Pulling and Lifting Machines

IS 3980:1982 Certified bearings ensure tested quality of the product. As the bearings are frequently employed in hard-to-reach or closed applications with no access for relubrication, any loss of quality tends to result in failure and downtime or expensive rework. Certification ensures that such a product will, under normal operating conditions of use, function in an efficient and safe manner. For producers, BIS certification serves to increase the credibility of a product and give its manufacturer a leg up on the competition as well as meet necessary Indian regulatory demands. It also helps in easy acceptance of them in the overseas markets. For end-users, certified bearings provide peace of mind in terms of uniform performance and self-lubrication properties along with longer equipment life that lowers running costs without increasing maintenance needs. Certification also prevents counterfeit or substandard items to be circulated which may result in failure of crucial operations.
