INTRODUCTION: THE PRECISION BEHIND INDUSTRIAL PERFORMANCE
In the high-performance world of rotating machinery, single row cylindrical roller bearings are pivotal. They offer excellent radial load capacity, high-speed capability, and minimal friction—making them essential in industries like steel, automotive, power generation, and heavy equipment manufacturing.
To maintain performance integrity and safety, these bearings must adhere to stringent technical requirements. That’s where IS 6457, the Indian Standard for single row cylindrical roller bearings, steps in. The Bureau of Indian Standards (BIS) mandates conformity to IS 6457 for certification and market legitimacy. For manufacturers aiming to meet this standard efficiently, Omega QMS Pvt. Ltd. provides critical consultancy services to simplify the certification process.
SUMMARY OF INDIAN STANDARD IS 6457
Scope
Covers single row cylindrical roller bearings, including through-hardened and case-hardened types. Excludes airframe and instrument precision bearings.
Performance Criteria
Hardness: Minimum of 58 HRC for rings and rollers.
Surface Finish: Max permissible roughness (Ra) as per IS 3073—critical for minimizing wear and friction.
Radial Internal Clearance: Must conform to IS 5935 for optimal bearing fit and reduced noise.
Load Ratings:
Dynamic: As per IS 3824
Static: As per IS 3823
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 SINGLE ROW RADIAL ROLLER BEARINGS UNDER IS 6457
The BIS certification process for tapered roller bearings ensures that the products conform to IS 6457 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 6457 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.
