INTRODUCTION: ENSURING PRECISION IN CRITICAL SLIDING INTERFACES
Thin-walled plain bearings are indispensable components in engines, compressors, gearboxes, turbines, and various machinery where low-friction movement and load support are required. These bearings, often used in high-speed and high-pressure environments, must perform reliably despite being compact and lightweight.
Given the critical nature of their application, maintaining dimensional accuracy, material uniformity, and load-bearing integrity is paramount. This is where IS 10203:1988, the Indian Standard for thin-walled plain bearings, plays a vital role. The Bureau of Indian Standards (BIS) mandates that these bearings conform to IS 10203 for certification purposes. For manufacturers aiming to get BIS-certified efficiently, Omega QMS Pvt. Ltd. provides expert end-to-end assistance.
SUMMARY OF INDIAN STANDARD IS 10203 – SPECIFICATION FOR THIN-WALLED PLAIN BEARINGS
Scope : Covers thin-walled, plain, cylindrical-type sliding bearings without flanges or oil grooves. Applies primarily to engine bearings and precision industrial machinery components.
Types Covered
Bearings with thin walls relative to diameter (typically with a wall thickness-to-diameter ratio less than 0.05). Can be lined or unlined depending on application and tribological requirements.
OVERVIEW OF THE QCO FOR BEARINGS
Quality Control Orders, or QCOs are a regulatory mechanism introduced by Ministry of Commerce under Bureau of Indian Standards (BIS) Act. They aim to ensure that products meet a minimum standard of quality and safety before being sold in the Indian market. For international traders, this means complying with BIS certification before exporting products like bearings to India.
India’s draft QCO for bearings emphasizes the quality standards and certification requirements for manufacturers, importers, and suppliers of these metals. The document mandates that all primary metals must conform to the relevant Indian Standards and manufacturers must obtain BIS certification before selling or distributing lead products in India.
BIS CERTIFICATION PROCESS FOR THIN-WALLED PLAIN BEARINGS UNDER IS 10203
The BIS certification process for thin-walled plain bearings ensures that the products conform to IS 10203 and meet stringent quality parameters. The certification follows a well-defined conformity assessment scheme under the BIS Act, 2016.
Steps Involved:
Application Submission: The manufacturer applies to BIS with product and factory details.
Product Testing: Samples are drawn from the production lot and tested for compliance with IS 6456 in BIS-recognized laboratories.
Factory Audit: BIS officers inspect the manufacturing process, quality control mechanisms, raw material traceability, and testing infrastructure.
Grant of License: If the product meets all specifications and the factory adheres to BIS standards, a license is granted to use the Standard Mark.
Ongoing Surveillance: BIS conducts periodic surveillance inspections and draws samples from the market or factory for re-testing.
