Cylindrical Roller Bearings FAG NJ226 -E-M1

The FAG NJ226 -E-M1 cylindrical roller bearing combines a 130 mm bore with a brass cage for high radial loads and single-sided axial guidance.

The NJ226 -E-M1 cylindrical roller bearing is a single-row rolling bearing designed for industrial applications involving demanding radial loads. Designed as an open bearing, the unit operates directly within the machine’s lubrication circuit. With an outer diameter of 230 mm and a width of 40 mm, this FAG product provides a robust bearing arrangement with standardised normal tolerance in accordance with tolerance class P0/PN (ABEC 1).

What is the NJ226-E-M1 cylindrical roller bearing suitable for?

This bearing functions as a support bearing in designs subject to predominantly radial forces and single-sided axial loads. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the bearing assembly to accommodate axial forces from one direction. In the opposite direction, the arrangement allows for axial displacement, which compensates for thermally induced changes in the shaft’s length. The inner ring can be removed from one side, which facilitates installation.

What are the distinctive features of the brass cage and this design?

The design suffix M1 refers to the brass cage, which guides the rollers even under vibrations and higher acceleration forces. The material is suitable for mechanically demanding operating conditions. The permissible temperature range is from –30 to +150 degrees Celsius. The standard radial bearing clearance ensures balanced running behaviour under normal operating conditions, provided that standard fits are used on the shaft and housing. The outer ring is designed without a lubrication groove or lubrication bore.
