Cylindrical Roller Bearings FAG NU216 -E-XL-M1-C3

The FAG NU216 -E-XL-M1-C3 single-row cylindrical roller bearing, measuring 80x140x26 mm, serves as a support bearing with a brass cage for high radial loads.

This open cylindrical roller bearing, model NU216 -E-XL-M1-C3, absorbs high radial forces due to the line contact between the rollers and raceways. As an NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from either side, which simplifies the separate installation of both bearing rings and compensates for axial length changes in the shaft during operation.

What is the NU216 -E-XL-M1-C3 cylindrical roller bearing suitable for?

It is used in bearing arrangements where purely radial loads occur and thermal linear expansion of the shaft must be accommodated. The roller bearing fulfils its function as a pure non-locating bearing. The solid brass cage guides the rolling elements within the raceway even under acceleration and vibration. As this is an open bearing without an integrated seal, lubrication is provided directly via the housing system.

What do ‘brass cage’ and ‘C3 clearance’ mean in relation to this bearing?

The designation with the suffix M1 indicates a solid brass cage, which provides strength under vibration loads. The C3 designation indicates increased radial bearing clearance. This additional radial clearance is useful when tight fits on the shaft and housing cause the inner ring to expand, or when operational temperature differences occur between the shaft and housing. The permissible temperature range is from -30 to +150 degrees Celsius, provided the standard tolerance in accordance with tolerance class P0/PN or ABEC 1 is observed.
