INTRODUCTION
Self-aligning roller bearings are designed to withstand heavy radial loads while accommodating angular misalignment, making them indispensable in industries such as mining, construction, automotive, and heavy machinery. These bearings can endure shaft deflection and mounting errors without compromising performance or durability.
To ensure consistency, quality, and reliability in such critical components, the Bureau of Indian Standards (BIS) has laid out a comprehensive standard — IS 6454. This standard governs the technical specifications and dimensional requirements for self-aligning roller bearings. For manufacturers aiming to meet BIS requirements and enhance market credibility, expert assistance from consultants like Omega QMS Pvt. Ltd. is invaluable.
SUMMARY OF INDIAN STANDARD IS 6454
IS 6454 specifies the requirements for self-aligning roller bearings, covering both single-row and double-row configurations. The standard ensures that bearings meet precise mechanical and dimensional tolerances, offering durability and performance in demanding applications. Types
- Single-row self-aligning roller bearings
- Double-row self-aligning roller bearings
Designation System: Bearings are designated with a structured code that includes:
- Bore diameter
- Dimension series
- Tolerance class (e.g., P5)
- Radial clearance group (e.g., C3)
- Tapered bore indicator (e.g., XK)
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 SELF ALLIGNING ROLLER BEARINGS UNDER IS 6454
The BIS certification process for self- aligning roller bearings ensures that the products conform to IS 6454 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 12102 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.
