Cylindrical Roller Bearings FAG NJ2312 -E-XL-M1A-C3

The FAG NJ2312 -E-XL-M1A-C3 cylindrical roller bearing, a single-row support bearing with a 60 mm bore, offers high radial load-carrying capacity and axial guidance properties.

This single-row cylindrical roller bearing, the NJ2312 -E-XL-M1A-C3 from FAG, absorbs heavy radial forces thanks to the line contact between the rolling elements. The open roller bearing has a bore of 60 mm, an outer diameter of 130 mm and a width of 46 mm. The NJ design acts as a support bearing: it guides the shaft in an axial direction, whilst the inner ring remains removable on one side for installation purposes. The component is manufactured to tolerance class P0/PN or ABEC 1.

In which installation scenarios does the NJ2312 -E-XL-M1A-C3 cylindrical roller bearing prove its worth?

This design is primarily used in shaft mountings where significant radial loads are present and the bearing is also required to accommodate one-sided axial forces. As the outer ring is designed without a lubrication groove or bore, lubricant is supplied via the housing design. The solid, externally guided brass cage withstands high accelerations and is suitable for applications involving vibrations or shock loads.

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

The designation C3 indicates a slightly increased radial clearance compared with the standard version. This additional clearance compensates for operational heating or tight fits, ensuring that the rollers roll freely during operation. The permissible temperature range is from –30 to +150 degrees. The solid brass cage, which is mounted on the outside, guides the rolling elements stably under dynamic loads. As this is an open design without seals, sealing is provided by adjacent components of the surrounding structure.
