Cylindrical Roller Bearings FAG NU320 -E-M1

The FAG NU320 -E-M1 single-row cylindrical roller bearing, measuring 100x215x47 mm, offers a high radial load capacity and functions as a separable idler bearing.

The NU320 -E-M1 cylindrical roller bearing is a single-row radial roller bearing from FAG, designed to withstand high radial loads. With a bore of 100 mm, an outer diameter of 215 mm and a width of 47 mm, this open bearing can withstand considerable transverse forces. As this design has no integrated seals, the bearing can be lubricated with oil or grease directly via the surrounding housing. It is manufactured to the standard tolerance class P0/PN (ABEC 1).

What is the NU320 -E-M1 cylindrical roller bearing suitable for as a floating bearing?

This bearing is primarily intended for bearing arrangements where thermally induced changes in shaft length must be compensated for without constraint. In the NU design, two fixed flanges on the outer ring guide the rollers, whilst the flangeless inner ring can be removed from both sides. This design allows for axial displacement between the shaft and the housing within the bearing. Typical applications are found in general mechanical engineering in bearing arrangements with purely radial force transmission.

What are the operational advantages of the M1 brass cage?

The brass cage (suffix M1) guides the cylindrical rollers evenly and withstands dynamic loads and vibrations. Brass is characterised by favourable sliding properties and absorbs mechanical stresses whilst maintaining its dimensional stability. In terms of design, this version is rated for a temperature range of -30 to +150 degrees. The bearing has standard radial clearance and an outer ring without a lubrication groove; therefore, the supply of lubricant via the bearing environment should be taken into account.
