Overview

Cylindrical roller bearing

Cylindrical roller bearings provide line contact between rollers and raceways, accommodating very high radial loads together with high-speed operation. Depending on the flange configuration (NU, NJ, N, NUP), they allow axial displacement or locate the shaft in one or both directions, and their separable design eases mounting and maintenance. They are widely used in gearboxes, electric motors and rolling-mill equipment for heavy-duty service.

Key features

Very high radial load capacity
High-speed capable with high rigidity
Separable design for easy mounting
Axial function selectable by flange type

Typical applications

Industrial electric motors
Gearboxes and reducers
Machine tool spindle support positions
Rolling mills, paper machines, and heavy machinery

Selection guidance

Choose the N, NU, NJ, or NUP design by load direction, axial locating requirement, cage material, internal clearance, and lubrication condition.
