Cylindrical Roller Bearings FAG NU2222 -E-XL-TVP2

The FAG NU2222 -E-XL-TVP2 cylindrical roller bearing, measuring 110 × 200 × 53 mm, is designed to accommodate high radial loads as a separable support bearing in mechanical engineering.

The NU2222 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding applications involving high transverse forces. With an inside diameter of 110 mm, an outside diameter of 200 mm and a width of 53 mm, this size is suitable for heavily loaded shaft mountings. The NU design features two fixed flanges on the outer ring, whilst the inner ring is designed without guide flanges. This allows the bearing to permit unimpeded axial displacement of the shaft directly over the roller raceway.

What function does the NU2222 -E-XL-TVP2 cylindrical roller bearing fulfil as a non-locating bearing?

This cylindrical roller bearing is primarily used as a pure non-locating bearing to safely support radial forces whilst allowing longitudinal movement of the supported shaft. The line contact of the cylindrical rollers provides a high radial load-carrying capacity under mechanical stress. Axial length changes, caused for example by thermal expansion during operation, are compensated for without constraint by the design within the bearing. To accommodate axial guiding forces, the shaft must be combined with an additional fixed bearing.

What are the characteristics of the polyamide cage and the open design?

The polyamide cage guides the cylindrical rollers evenly and, due to its low weight, reduces the moving masses. The design is suitable for operating temperatures ranging from –30 to +120 degrees Celsius. As the inner ring can be removed from both sides, the inner and outer rings can be mounted separately on the shaft and housing. The open bearing has no integrated seals and no groove or lubrication bore in the outer ring, so lubricant is supplied via the bearing housing.
