Single Row Cylindrical Roller Bearings Overview

Single row cylindrical roller bearings are designed primarily for high radial loads. Line contact between the rollers and raceways provides higher radial load capacity, greater rigidity and better impact resistance than ball bearings of comparable dimensions.

CHG manufactures high-precision single row cylindrical roller bearings with optimized internal geometry and customized configurations for rolling mills and other heavy industrial equipment.

High Load Carrying Capacity

The line-contact design creates a larger load-bearing area, enabling the bearing to withstand high radial loads.

  • High radial load capacity
  • Excellent impact resistance
  • High rigidity
  • Long service life

Separable Bearing Design

The inner ring, outer ring, and roller-and-cage assembly can be separated, simplifying installation and maintenance.

  • Easy installation and removal
  • Convenient maintenance
  • Suitable for interference-fit applications
