Cylindrical Roller Bearings FAG NU1032 -M1A-C3

The FAG NU1032 -M1A-C3 single-row cylindrical roller bearing, with a 160 mm bore, solid brass cage and C3 clearance, offers high radial load-carrying capacity when used as a non-locating bearing.

The FAG NU1032 -M1A-C3 cylindrical roller bearing is designed as a single-row radial roller bearing for demanding industrial applications. Thanks to the line contact between the cylindrical rollers and raceways, this design absorbs heavy radial forces whilst maintaining high rigidity. With key dimensions of a 160 mm bore, 240 mm outer diameter and 38 mm width, this design is suitable for compact installation spaces. It is manufactured to the standard tolerance class P0/PN (ABEC 1).

In which applications is the NU1032 -M1A-C3 idler bearing used?

This radial roller bearing is primarily used in bearing arrangements where purely radial loads must be supported and axial length changes of the shaft must be compensated for. In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless and can be removed from both sides. As a result, the unit serves as a true idler bearing in general mechanical engineering and in heavy-duty industrial gearboxes.

What are the advantages of the solid brass cage and the C3 clearance?

The two suffixes denote specific design features of this bearing type. The externally guided solid brass cage, designated M1A, offers high strength and guides the rollers stably within the raceway, even under vibration or shock loads. The increased radial clearance (C3) prevents the rolling elements from seizing up due to thermal expansion or tight fits. The open bearing is designed for an operating temperature range of -30 to +150 degrees.
