Cylindrical Roller Bearings FAG NJ312 -E-XL-TVP2

The FAG NJ312 -E-XL-TVP2 cylindrical roller bearing accommodates high radial loads and supports shafts axially in one direction with a bore diameter of 60 mm.

The FAG NJ312 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With a bore of 60 mm, an outer diameter of 130 mm and a width of 31 mm, this design offers a high radial load capacity. The open design allows for use in oil- or grease-lubricated systems. Thanks to its standard radial clearance and manufacture to tolerance class P0 (ABEC 1), the bearing is suitable for standardised fits in machine and gearbox construction.

In which bearing arrangements is the NJ312 -E-XL-TVP2 cylindrical roller bearing used?

As a support bearing, this design accommodates not only high radial loads but also one-way axial forces. Typical applications include shaft mountings subject to high radial loads and one-way axial guidance. The inner ring, which can be removed from one side, allows the shaft to be fixed axially in one direction, whilst the opposite side compensates for thermal length changes without constraint. Designers make specific use of this property in fixed-floating bearing arrangements where defined axial shaft guidance is required.

What features does the TVP2 polyamide cage offer when selecting bearings?

The designation TVP2 indicates a polyamide cage that reduces the weight of the rolling element set. Compared with metal cages, polyamide effectively dampens running noise and shock loads. When planning, please note the permissible operating temperature range of -30 to +120 degrees Celsius. Furthermore, the outer ring has neither a ring groove nor a lubrication bore. Lubricant must therefore be supplied via the surrounding housing structure to lubricate the raceways of the open bearing.
