Cylindrical Roller Bearings FAG NJ312 -E-XL-M1-C3

The FAG NJ312 -E-XL-M1-C3 cylindrical roller bearing, measuring 60x130x31 mm, with a brass cage and C3 clearance, offers a high-load-capacity solution for demanding industrial drives.

The FAG NJ312 -E-XL-M1-C3 cylindrical roller bearing is designed as a single-row radial roller bearing for heavy radial loads. In the NJ design, this version acts as a support bearing: fixed flanges on the outer ring and a single-sided flange on the inner ring absorb axial forces in one direction. With a 60 mm bore, 130 mm outer diameter and 31 mm width, this open bearing has proven its worth in demanding shaft mountings and industrial drive units.

What is the NJ312 -E-XL-M1-C3 cylindrical roller bearing suitable for as a support bearing?

This cylindrical roller bearing is particularly suitable for shaft mountings subject to high radial forces, where axial displacement in one direction must also be accommodated. The inner ring can be removed from one side, which facilitates the separate assembly of the inner and outer rings. Designs involving thermal expansion of the shaft benefit from this axial displacement, whilst guidance in the opposite direction remains stable.

This design is typically used in rotating shaft assemblies and heavy-duty industrial drives where axial compensation movements are required.

What do the brass cage and the C3 clearance mean for your design?

The solid brass cage (M1) guides the cylindrical rollers securely and withstands severe mechanical vibrations as well as high acceleration forces. In combination with the increased radial clearance (C3), smooth running is maintained even when operational heating or tight fits reduce the radial clearance. With a permissible temperature range of -30 to +150 degrees, the bearing operates reliably under thermally demanding environmental conditions.
