NNU41/850-M FAG roller bearings

FAG  double row cylindrical roller bearings comprise solid bearing rings and cylindrical roller and cage assemblies with solid cages.
The bearings are suitable for very high radial loads and high speeds. They are separable and are therefore easier to mount and dismount.
As a result, both bearing rings can be given a tight fit. All the designs described are non-locating bearings, since one of
the bearing rings in each case is without ribs.

Design 1 ■ Outer ring with three rigid ribs, inner ring without ribs,
lubrication groove and lubrication holes in the outer ring,
brass double comb cage
■ Bearings of dimension series 49 with standardised main
dimensions and designations, in some cases in tolerance
class P5, for high speed work rolls in rolling mills
■ Non-standardised bearings (Z-5..ZL) with normal accuracy
■ Application:
– for example in rolling mills and plastics calenders.
Design 2 ■ Outer ring with three rigid ribs, inner ring without ribs,
no lubrication groove and lubrication holes in the outer ring,
brass double comb cage
■ Bearings of series NNU41 or special bearings (Z-5..ZL)
■ Application:
– for example in grinding track mills.
