Tag: Cylindrical Roller Bearing

Role in Rolling Mills While rolling mills utilize various bearing types, multi-row cylindrical roller bearings are specifically engineered for applications requiring exceptional radial load capacity and rigid support in mill stands. Typical Installations: Backup rolls in 4-high/6-high mills Plate mill support rolls Continuous casting machine rolls Non-drive end applications Technical Advantages Optimized Load Distribution – […]

The structure of cylindrical roller bearings 1. Detailed Structural Components Cylindrical roller bearings consist of four fundamental components that work in precise coordination: Outer Ring Manufactured from high-grade chromium steel (typically GCr15 or SAE 52100) Features hardened raceways with 58-64 HRC hardness May include ribbed designs for axial displacement control Inner Ring Precision-ground to micron-level […]

This guide details eight key types of single-row cylindrical roller bearings — N, NU, NJ, NF, NUP, NFP, RN, and RNU—explaining their rib designs, axial load capabilities, and application suitability. Whether you need bidirectional axial movement support or heavy-duty rotational stability, this technical breakdown will guide your selection. 1. N-Type Cylindrical Roller Bearings Key Features: […]
