FAG NJ218-E-M1-C3 Cylindrical Roller Bearing

• Cylindrical roller bearings NJ are semi-locating bearings
• The outer and inner ring can be axially displaced relative to each other in one direction only by the value “s”
• Semi-locating bearings can support not only high radial forces but also axial forces in one direction and can therefore guide shafts axially in one direction
• The bearings are supplied without seals
• Single row cylindrical roller bearings with cage can be used at operating temperatures from –30 °C to +150 °C

Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling. The cage type bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with the suffix E have a higher capacity roller set and are thus designed for very high load carrying capacity. The bearings are separable and are therefore easier to fit and dismantle. Both bearing rings can be given a tight fit by this process. Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings. Numerous sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables. Bearings of X-life quality have, for example, lower roughness Ra and higher geometrical accuracy of the raceways than comparable designs that are not X-life. As a result, these bearings have higher load carrying capacity and longer life for the same dimensioning. In certain applications, this means that a smaller bearing arrangement can be designed.
