Cylindrical Roller Bearings FAG NJ314 -E-XL-TVP2-C3

The FAG NJ314 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 70x150x35 mm, offers high radial load-carrying capacity and axial guidance in one direction.

The FAG NJ314 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. With a bore of 70 mm, an outside diameter of 150 mm and a width of 35 mm, this design can withstand high radial loads. Designed as an open bearing, the component can be flexibly integrated into existing lubrication circuits. The tolerance class P0/PN indicates that the raceways are manufactured for continuous operation.

How does the NJ314 -E-XL-TVP2-C3 cylindrical roller bearing accommodate radial and axial loads?

Design engineers primarily use this design where strong radial forces are present and the shaft is to be fixed axially at one end. Designed as a support bearing with two fixed flanges on the outer ring and one flange on the inner ring, the bearing accommodates axial forces from one direction. In the opposite direction, the design allows for axial displacement. The inner ring is removable from one side, which facilitates the separate assembly of the shaft and housing.

What advantages do the polyamide cage and C3 clearance offer in this design?

The polyamide cage guides the cylindrical rollers with low mass, which reduces friction during operation and promotes quiet running. Together with the increased radial clearance (C3), the component is suitable for operating conditions involving thermal expansion or tight fits. The permissible temperature range is from -30 to +120 degrees. When designing the bearing mounting, it should be noted that the outer ring is designed without a groove or lubrication bore.
