Cylindrical Roller Bearings FAG NJ320 -E-M1

The FAG NJ320 -E-M1 single-row cylindrical roller bearing, with dimensions of 100 × 215 × 47 mm, can accommodate very high radial forces and supports axial loads on one side.

The NJ320 -E-M1 cylindrical roller bearing features cylindrical rollers which, through line contact, can handle high radial loads. FAG manufactures this version with standard radial clearance and the standard tolerance class P0/PN or ABEC 1. Thanks to its solid brass cage, this open bearing is suitable for high mechanical loads. The design covers a temperature range from –30 to +150 degrees, provided that a suitable lubricant is used in the surrounding housing.

What loads and bearing applications does the NJ320 -E-M1 cylindrical roller bearing handle?

This single-row bearing functions as a classic support bearing in mechanical engineering. In addition to heavy radial loads, it also absorbs axial forces acting on the shaft from one direction. In the opposite direction, the bearing allows for axial displacement of the shaft. The solid brass cage guides the rolling elements precisely, even under vibration and at high speeds.

What is the function of the NJ design with a brass cage?

The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the inner ring to be pulled off towards the opposite side, which facilitates the separate installation of both bearing rings in the housing and on the shaft. The brass material ensures the rollers are dimensionally stable. As the outer ring is designed without a groove or lubrication bore, grease or oil is supplied directly via the open bearing cavity.
