Cylindrical Roller Bearings FAG NJ311 -E-XL-TVP2

The FAG NJ311 -E-XL-TVP2 cylindrical roller bearing is designed for shafts with a 55 mm bore under high radial loads and supports axial loads on one side.

The FAG NJ311 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing for industrial applications subject to significant radial loads. With a bore of 55 mm, an outer diameter of 120 mm and a width of 29 mm, this size offers a compact guidance solution with high load-carrying capacity. The open design without seals allows for direct lubricant supply via the housing. Thanks to tolerance class P0, the roller bearing meets standard precision requirements in general mechanical engineering.

In which bearing arrangements is the NJ311 -E-XL-TVP2 cylindrical roller bearing used?

This roller bearing is used where high radial forces are present and, at the same time, single-sided axial guidance of the shaft is required. The NJ design functions as a support bearing: the inner ring has a fixed flange, whilst the opposite side allows for axial displacement. As a result, the bearing arrangement compensates for thermal length changes in the shaft in one direction. Applications include bearing arrangements where defined axial support is required whilst the main load is radial.

What function does the TVP2 polyamide cage fulfil during operation?

The integrated TVP2 polyamide cage guides the cylindrical rollers evenly and reduces the weight compared with solid metal cages. The elastic cage material dampens impacts within the rolling element set and promotes quiet operation. When designing the bearing, please note the permissible temperature range of -30 to +120 degrees Celsius specified for the material. As the outer ring is manufactured without a groove or lubrication bore, the lubricant is supplied from the end face. Furthermore, the inner ring, which can be removed from one side, facilitates assembly.
