Overview

Single row full complement cylindrical roller bearing, NCF design

Single row full complement cylindrical roller bearings are designed to accommodate very high radial loads in combination with moderate speeds. The bearings incorporate a maximum number of rollers as they are not equipped with a cage. Having two integral flanges on the inner ring and one flange on the outer ring, NCF design bearings can accommodate axial displacement in one direction. A retaining ring on the outer ring holds the bearing together. The retaining ring should not be loaded axially during operation.

Key features

Very high radial load carrying capacity
High radial stiffness
Long service life
Locate the shaft axially in one direction

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.
