Cylindrical Roller Bearings FAG NU326 -E-XL-M1-C3

The FAG NU326 -E-XL-M1-C3 cylindrical roller bearing, with a bore of 130 mm, an outside diameter of 280 mm and a width of 58 mm, can withstand high radial loads.

The NU326 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing in a floating arrangement, manufactured to standard tolerance class P0/PN or ABEC 1. Two fixed flanges on the outer ring guide the set of rollers, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate assembly of both bearing rings. Designed as an open bearing, the construction operates within a temperature range of -30 to +150 degrees.

What functions does the NU326 -E-XL-M1-C3 cylindrical roller bearing fulfil as a non-locating bearing?

This roller bearing is suitable for bearing arrangements subject to high radial loads where axial displacement must be accommodated. Thanks to the flangeless NU design, the bearing functions purely as a non-locating bearing. The unit compensates axially between the raceways for thermally induced changes in shaft length. The outer ring has neither a lubrication groove nor a lubrication bore, so the lubricant is supplied via the housing or adjacent components.

What are the characteristics of the brass cage and C3 clearance?

The solid brass cage M1 guides the cylindrical rollers precisely within the bearing. The material is characterised by high resistance to vibrations and dynamic loads. This design is complemented by the slightly increased radial bearing clearance (C3). This increased internal clearance compensates for fit allowances and temperature differences between the inner and outer rings during operation, thereby preventing the rolling elements from seizing.
