Cylindrical Roller Bearings FAG NUP220 -E-XL-TVP2

The FAG NUP220 -E-XL-TVP2 cylindrical roller bearing is a single-row fixed bearing with a 100 mm bore, an 180 mm outer diameter and a polyamide cage.

As a radial roller bearing, the NUP220 -E-XL-TVP2 cylindrical roller bearing withstands high radial loads and supports shafts axially in both directions. With main dimensions of 100 × 180 × 34 mm and the NUP design, this version is used as a fixed bearing in mechanical engineering. The manufacturer, FAG, equips this open bearing with a dimensionally stable polyamide cage and standard radial clearance, which ensures quiet operation at industrial speeds.

In which bearing arrangements does the NUP220 -E-XL-TVP2 cylindrical roller bearing act as a fixed bearing?

This fixed bearing is particularly suitable for bearing arrangements in mechanical engineering where high radial forces occur and axial fixation of the shaft is required at the same time. Thanks to two fixed flanges on the outer ring, a fixed flange on the inner ring and a separate flange disc, the bearing supports axial forces on both sides.

Design engineers frequently use this arrangement in combination with floating bearings to compensate for thermal length changes in the shaft whilst simultaneously creating a defined fixed point within the housing.

What are the key features of the TVP2 polyamide cage in this fixed bearing?

The polyamide cage (designation TVP2) is characterised by its low weight and elastic material properties. Compared with solid metal cages, the lightweight plastic material reduces inertial forces during rapid speed changes and dampens operating noise.

Please note the permissible temperature range of -30 to +120 degrees Celsius, as this is primarily determined by the polyamide material. As the outer ring has no groove or lubrication bore, apply grease or lubricating oil directly to the rolling element set during assembly or via the housing.
