Cylindrical Roller Bearings FAG NU236 -E-XL-M1A-C3

The FAG NU236 -E-XL-M1A-C3 cylindrical roller bearing, with dimensions of 180 × 320 × 52 mm, withstands high radial loads and functions as a separable idler bearing.

The FAG NU236 -E-XL-M1A-C3 cylindrical roller bearing is a single-row rolling bearing for industrial applications involving high radial loads. With an inner diameter of 180 mm, an outer diameter of 320 mm and a width of 52 mm, this open bearing can withstand demanding mechanical stresses. The NU design is characterised by two fixed flanges on the outer ring, whilst the inner ring is flangeless. This enables the component to compensate for axial length changes in the shaft within the bearing with low friction.

Where is the NU236 -E-XL-M1A-C3 cylindrical roller bearing typically used?

This design is primarily used in industrial plant and heavy machinery. It fulfils its purpose wherever purely radial loads occur and thermal length changes in the shaft require a free-end bearing. As the inner ring can be removed from both sides, the separate installation of the shaft and housing is straightforward. In combination with a fixed bearing, this configuration provides a reliable bearing arrangement for large shaft diameters.

What do the designations M1A and C3 mean for the NU236 cylindrical roller bearing?

The suffix M1A denotes a solid brass cage with an external guide. This cage type is designed for severe vibrations and high dynamic forces. The increased radial clearance C3 provides additional radial play. This helps to prevent the rollers from jamming when temperature differences arise between the inner and outer rings, or when tight fits cause the inner ring to expand. With a permissible temperature range of -30 to +150 degrees, tolerance class P0 (ABEC 1) is suitable for standardised industrial requirements.
