Cylindrical Roller Bearings FAG NU2315 -E-XL-M1-C3

The FAG NU2315 -E-XL-M1-C3 cylindrical roller bearing, an open idler bearing with a brass cage, accommodates high radial forces on shafts with a diameter of 75 mm.

The NU2315 -E-XL-M1-C3 cylindrical roller bearing is a single-row roller bearing from FAG designed for highly loaded bearing arrangements. With a bore of 75 mm, an outer diameter of 160 mm and a width of 55 mm, the design supports heavy radial loads. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, facilitating separate installation.

What function does the NU2315 -E-XL-M1-C3 cylindrical roller bearing fulfil as a non-locating bearing?

In a bearing arrangement, this design serves purely as a non-locating bearing to accommodate transverse forces. Due to the line contact between the rollers and raceways, the design can withstand high radial loads. As the inner ring has no retaining flanges, this design allows for axial compensation of thermal length changes in the shaft during operation. For axial guidance, the bearing arrangement must be combined with a separate fixed bearing.

What are the distinctive features of the brass cage and C3 clearance?

This model features a solid brass cage (M1) which guides the roller elements under dynamic loads. The increased radial clearance (C3) compensates for operational heating and tight fit allowances to prevent the rolling elements from becoming stressed. The permissible temperature range is from –30 to +150 degrees Celsius. As this is an open design without integrated seals and without a lubrication bore in the outer ring, the lubricant must be selected to suit the specific application.
