Cylindrical Roller Bearings FAG NU2313 -E-M1

The FAG NU2313 -E-M1 cylindrical roller bearing, measuring 65 × 140 × 48 mm, is an open idler bearing designed to accommodate high radial loads during operation.

The NU2313 -E-M1 cylindrical roller bearing is a single-row radial roller bearing with a 65 mm bore, an outer diameter of 140 mm and a width of 48 mm. In this version from FAG, the design features a solid brass cage and standard radial clearance. The open bearing has no integrated seals, allowing lubricants to reach the contact surfaces unhindered. The unit operates within a temperature range of -30 to +150 degrees Celsius.

What is the NU2313 -E-M1 cylindrical roller bearing suitable for under high radial loads?

This single-row cylindrical roller bearing is primarily suitable for bearing arrangements subject to high radial loads. Due to its NU design, the bearing functions purely as a non-locating bearing, with the outer ring having two fixed flanges whilst the inner ring is flangeless. This allows the component to compensate directly within the bearing, without any constraint, for axial length changes in the shaft relative to the surrounding housing. Typical applications include rigid shaft mountings in general mechanical engineering, where operational thermal expansion must be accommodated.

What are the functional features of the brass cage and the NU design?

The cage design and installation conditions play a key role in the design of the bearing arrangement. The brass cage guides the cylindrical rollers stably within the rolling element ring and is suitable for demanding operating conditions. As the inner ring can be removed from both sides, the inner and outer rings can be fitted separately onto the shaft and housing. This considerably simplifies installation and subsequent maintenance work. Prior to installation, the tolerance class P0/PN (ABEC 1) and a suitable external seal for the bearing housing must be taken into account.
