Cylindrical Roller Bearings FAG NU319 -E-XL-M1A-C3

The FAG NU319 -E-XL-M1A-C3 cylindrical roller bearing, measuring 95 x 200 x 45 mm, offers high radial load-carrying capacity as a non-locating bearing with a robust brass cage.

The FAG NU319 -E-XL-M1A-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the line contact of the cylindrical rollers, this rolling bearing can withstand very high radial loads. The inner ring has no flanges and can be removed from either side, enabling the bearing to function purely as a floating bearing and to compensate for changes in shaft length during operation without constraint. It is manufactured to the standard tolerance class P0/PN or ABEC 1.

In which designs is the NU319 -E-XL-M1A-C3 non-locating bearing used?

This non-locating bearing is used in shaft mountings where high radial loads occur and thermally induced changes in shaft length need to be compensated for. As this design cannot accommodate axial forces, it is typically fitted in combination with a separate locating bearing on the opposite side. The open bearing design allows for flexible lubricant supply via the housing.

What are the distinctive features of the solid brass cage and C3 clearance?

The externally mounted solid brass cage promotes high mechanical stability under vibrations, shock loads or accelerations. The increased radial clearance (C3) provides additional radial play in the event that operational heating or tight fits lead to a reduction in bearing clearance. The permissible temperature range is from -30 to +150 degrees. As the outer ring has neither a lubrication groove nor lubrication holes, lubrication is provided by design via the housing chamber.
