This Indian Standard provides comprehensive specifications and requirements for single-row cylindrical roller bearings. The standard defines the parameters for bearing components, including the inner and outer rings, rollers, cages, and raceway design. It also covers permissible tolerances, radial internal clearances, and methods for verifying conformity. Single-row cylindrical roller bearings are designed for higher radial load capacity and operate efficiently in conditions where high speed and precision alignment are necessary. These bearings minimize friction and allow axial displacement within the bearing itself, making them ideal for applications involving thermal expansion or shaft misalignment.

The IS 6457:2024 standard includes provisions for:

• Dimensional and geometric accuracy
• Material specifications for rings and rollers
• Lubrication and surface finish quality
• Fatigue and endurance testing under dynamic loads
• Noise and vibration performance evaluation

Compliance with this standard ensures that the bearing delivers consistent rotational performance, reduced wear, and extended service life under demanding operational environments.

For Manufacturers:
Obtaining BIS certification provides proof of adherence to Indian quality benchmarks and improves brand credibility in both domestic and export markets. It helps manufacturers ensure uniform production quality, meet tender and government supply requirements, and reduce product rejection due to non-compliance. Certification also enhances customer confidence and gives access to wider industrial segments that demand standard-compliant products. For End Users:
Certified bearings guarantee higher reliability, lower maintenance costs, and improved machinery efficiency. They reduce the risk of premature bearing failure caused by fatigue, misalignment, or material inconsistencies. This directly contributes to greater productivity, reduced downtime, and longer equipment lifespan — particularly important in sectors like automotive, railways, power generation, and heavy engineering.
