Cylindrical Roller Bearings
Cylindrical rollers provide line contact with the raceways for radial load support and rigidity. Rib arrangements determine axial displacement and locating capability.
- Single-row and multi-row configurations
- N and NU types allow axial displacement
- NJ and NUP arrangements provide locating functions
PRODUCT OVERVIEW
52172 — Cylindrical Roller Bearings
Cylindrical rollers provide line contact with the raceways for radial load support and rigidity. Rib arrangements determine axial displacement and locating capability.
Axial capability depends on the rib arrangement. Do not treat N, NU, NJ and NUP as interchangeable designs.
Typical application areas: Electric motors, Gearboxes, Rolling mills, Machine tool spindles. Suitability is reviewed against the specific operating conditions and bearing arrangement.
