BIS CERTIFICATION FOR PLAIN BEARINGS PRESSED BIMETALLIC HALF THRUST WASHERS IS 9764 (Part 2)

Published Date: Oct 10, 2025 4 min Read

BIS certification is mandatory for Plain Bearings Pressed Bimetallic Half Thrust Washers under IS 9764 (Part 2):2022. These components are essential in controlling friction and wear between moving and stationery parts of an automobile engine, industrial machinery, or any mechanical device. The reliability, efficiency and safety of equipment are closely related to the quality of the thrust washers, in that they control axial displacement and make sure everything is working smoothly. "Certification guarantees that the manufacturer meets the necessary quality standards, so end users can trust in the reliability and longevity of these bearings."

IS 9764 (Part 2):2022 – Plain Bearings Pressed Bimetallic Half Thrust Washers

This Indian Standard covers requirements, dimensions, materials and performance criteria for pressed bimetallic half thrust washers employed in plain bearings. But there is a disadvantage of conventional washers of the above-mentioned type, that the prior art represents these washers from without steel with a bonded bearing alloy layer both in terms of strength and load-carrying capacity as well low-frictional here times. It includes material, hardness, surface finish, dimensional accuracy and mechanical properties. It also provides test methods for steel backing-to-bearing alloy bond, wear resistance, fatigue strength and oil compatibility. Compliance with IS 9764 (Part 2):2022 guarantees that the thrust washers deliver consistent quality and can perform under high-load, high-temperature conditions. Thrust Washers are Designed to provide optimum dirt separation, to ensure maximum performance, and minimize wear. When these washers are inadequate, or if material quality or interpretation of a washing diagram is at fault, failure can occur resulting in undue wear, misalignment, and/or vibration as well as equipment destruction. BIS certification ensures the product to be verified extensively for safety, long-lasting and mechanical strength, and also minimize loss.

Benefits of BIS Certification for Manufacturers and Users

For members of the industries, BIS certification adds credibility to their products, makes sure that statutory requirements are fulfilled and increases consumer confidence in the quality of these goods in domestic and international markets. It also gives a competitive advantage by assuring consumers of consistent quality. The result for end-users is longer life, lower maintenance costs and faster equipment reliability. Furthermore, it keeps the sub-standard and counterfeit products out of the market so that only tested and reliable parts go into vital equipment.
