Cylindrical Roller Bearings FAG NU236 -E-M1

The FAG NU236 -E-M1 cylindrical roller bearing, with a 180 mm bore, brass cage and separately mountable rings, provides a robust floating support for heavy-duty industrial applications.

The NU236 -E-M1 cylindrical roller bearing is a single-row radial roller bearing of the NU design. FAG manufactures this version with solid flanges on the outer ring, whilst the inner ring is flangeless. Thanks to this design, the bearing compensates for axial length changes in the shaft directly between the rollers and the inner raceway. With dimensions of 180 mm bore, 320 mm outer diameter and 52 mm width, the component can withstand very high radial forces.

What is the NU236 -E-M1 cylindrical roller bearing suitable for as a floating bearing?

This design is used in mechanical and plant engineering where shaft deflection or thermal length changes need to be accommodated without constraint. It is suitable for bearing arrangements subject to high radial loads and axial displacement. The open bearing design allows for flexible integration into lubrication circuits using oil or grease. As the inner ring can be removed from both sides, the shaft and housing can be fitted independently of one another during assembly.

What are the distinctive features of the brass cage in this FAG design?

The brass cage (M1) provides stable guidance for the cylindrical rollers and is characterised by high strength under vibrations or impact loads. The permissible temperature range extends from –30 to +150 degrees Celsius, ensuring that the bearing remains dimensionally stable even under increased operating heat. The bearings are manufactured to the standard tolerance class P0/PN (corresponding to ABEC 1) with standard radial clearance. The outer ring has no ring groove or lubrication bore, so lubrication is supplied via the surrounding structure.
