Cylindrical Roller Bearings FAG NJ222 -E-M1

The single-row cylindrical roller bearing NJ222 -E-M1, with a brass cage and dimensions of 110 × 200 × 38 mm, withstands high radial loads and serves as a support bearing.

The NJ222 -E-M1 cylindrical roller bearing is an open roller bearing with the main dimensions of 110 mm bore, 200 mm outer diameter and 38 mm width. Due to the line contact between the rollers and raceways, this bearing can withstand high radial loads. It features a standard radial clearance and tolerance class P0/PN (ABEC 1). Manufactured by FAG, this version is designed for operating temperatures ranging from -30 to +150 °C and is suitable for industrial powertrains.

What is the NJ222 -E-M1 cylindrical roller bearing suitable for in industrial plant?

This support bearing is suitable for bearing arrangements subject to high radial loads where axial forces act in one direction. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring, allowing for axial displacement in the opposite direction.

Typical applications include industrial drives and gearbox assemblies subject to combined loads. The separable design, with an inner ring that can be removed from one side, facilitates installation and the replacement of components during maintenance work.

What are the key features of the brass cage in the NJ222 -E-M1 design?

The solid brass cage, designated M1, guides the rollers precisely and offers high mechanical strength. This material withstands high accelerations, shock loads and vibrations during operation.

As this is an open bearing without an integrated seal, the adjacent structure must be fitted with an external seal to protect against dirt and moisture. The outer ring has no groove or lubrication bore, so the lubricant should be supplied into the bearing chamber from the side.
