Cylindrical Roller Bearings FAG NU2218 -E-XL-TVP2

The FAG NU2218 -E-XL-TVP2 cylindrical roller bearing, as an open idler bearing measuring 90 × 160 × 40 mm, can accommodate high radial loads.

The NU2218 -E-XL-TVP2 cylindrical roller bearing belongs to the group of single-row radial roller bearings and is characterised by line contact between the rolling elements and raceways. This design accommodates high radial loads. With a bore of 90 mm, an outside diameter of 160 mm and a width of 40 mm, this design is suitable for demanding industrial applications. The open bearing has standard radial clearance and operates within a temperature range of -30 to +120 degrees Celsius.

When is the NU2218 -E-XL-TVP2 cylindrical roller bearing used as a non-locating bearing?

This cylindrical roller bearing is designed for bearing arrangements where predominantly radial forces occur and, at the same time, thermal length changes in the shaft need to be compensated for. The NU design functions purely as a non-locating bearing: The outer ring guides the roller set between two fixed flanges, whilst the inner ring has no flanges. This allows the shaft to move axially relative to the housing without constraint when it heats up during operation. Applications can be found in industrial bearing arrangements with separate fixed and floating bearing configurations.

What are the characteristics of the polyamide cage and the free-end bearing design?

The polyamide cage (TVP2) guides the rollers evenly and promotes vibration-damped operation whilst maintaining a low weight. As the inner ring can be removed from both sides, the bearing rings can be fitted separately. This simplifies installation and subsequent inspection. The component complies with tolerance class P0/PN (ABEC 1). As an open roller bearing without sealing washers or a lubrication groove on the outer ring, it requires a clean installation environment and a supply of lubricant via the bearing housing.
