Cylindrical Roller Bearings FAG NJ318 -E-XL-M1A-C3

The FAG NJ318 -E-XL-M1A-C3 cylindrical roller bearing, measuring 90 x 190 x 43 mm, offers high radial load capacity, a brass cage and increased C3 bearing clearance for demanding industrial applications.

The NJ318 -E-XL-M1A-C3 cylindrical roller bearing is a single-row radial roller bearing manufactured by FAG. The design features a cylindrical bore of 90 mm, an outer diameter of 190 mm and a width of 43 mm. Thanks to the line contact of the rollers, this design can withstand high radial loads. The open bearing has no integrated sealing washers and is designed for operating temperatures ranging from -30 to +150 degrees.

What is the function of the NJ318 -E-XL-M1A-C3 support bearing design?

The support bearing design is suitable for bearing arrangements subject to dominant transverse forces and single-sided axial shaft guidance. To this end, the inner ring has a solid flange, whilst the opposite side remains flangeless. As a result, the component absorbs axial guidance forces from one direction, but allows axial displacement in the opposite direction to compensate for operational thermal expansion of the shaft.

What are the characteristics of the brass cage and C3 radial bearing clearance?

The solid brass cage, which is guided on the outer edge, enables precise roller guidance and is characterised by high strength under vibrations or impact loads. The version with bearing clearance class C3 has a slightly increased radial clearance compared with standard clearance. This prevents the rolling elements from becoming stressed when temperature differences arise between the inner and outer rings during operation, or when tight fits are selected for the shaft and housing.
