Cylindrical Roller Bearings FAG NU2319 -E-XL-M1-C3

The FAG NU2319 -E-XL-M1-C3 cylindrical roller bearing is an open, single-row non-locating bearing measuring 95 × 200 × 67 mm, designed for heavy radial loads.

The FAG NU2319 -E-XL-M1-C3 cylindrical roller bearing can withstand very high radial forces. The cylindrical rollers create a wide contact area with the raceways, giving the rolling bearing high rigidity. It is manufactured to tolerance class P0/PN (ABEC 1). As this is an open bearing without a seal, lubrication is provided by the surrounding housing structure.

What is the NU2319 -E-XL-M1-C3 cylindrical roller bearing suitable for?

This cylindrical roller bearing is primarily used for purely radial loads. The NU design acts as a non-locating bearing, as the outer ring has fixed flanges, whilst the inner ring is flangeless. As a result, the design freely compensates for axial length changes in the shaft – for example, due to thermal expansion – within the bearing. Relevant areas of application include situations where rigid shaft mountings must accommodate high transverse forces and allow for axial length compensation.

What are the advantages of the brass cage and the C3 clearance?

The M1 version features a solid brass cage. This cage material ensures that the rollers operate with low vibration and mechanical stability, even under high acceleration. In addition, this version features an increased radial clearance of class C3. This slightly increased radial clearance helps to prevent the rolling elements from becoming stressed when temperature differences occur between the inner and outer rings during operation, or when tight fits cause the inner ring to expand. The permissible temperature range is between –30 and +150 degrees Celsius.
