Cylindrical Roller Bearings FAG NU320 -E-XL-TVP2-C3

The FAG NU320 -E-XL-TVP2-C3 cylindrical roller bearing, with a 100 mm bore, offers high radial load-carrying capacity as a separable idler bearing for demanding industrial drives.

This single-row cylindrical roller bearing NU320 -E-XL-TVP2-C3 from FAG, as a radial rolling bearing, primarily absorbs high radial forces. With key dimensions of 100 mm inner diameter, 215 mm outer diameter and 47 mm width, it complies with the standard tolerance P0/PN (ABEC 1). As it is designed as an open bearing, the bearing housing requires external sealing and suitable lubrication. The polyamide cage guides the rolling elements and is suitable for operating temperatures ranging from -30 to +120 degrees.

How does the NU320 -E-XL-TVP2-C3 cylindrical roller bearing, when used as a support bearing, absorb radial forces?

The NU design is suitable for bearing arrangements where high radial loads occur and axial length changes need to be compensated for. Two fixed flanges on the outer ring guide the rollers, whilst the inner ring has no flanges. This allows the inner ring to be removed from both sides and fitted separately. The idler bearing compensates for thermal linear expansion of the shaft without constraint within the bearing.

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

The suffix TVP2 denotes a solid polyamide cage, which ensures quiet running and low weight. The designation C3 also indicates an increased radial clearance compared with the standard design. This additional bearing clearance counteracts any straining of the rolling elements should temperature differences arise between the inner and outer rings during operation, or should tight fits reduce the radial clearance. The design is suitable for operating temperatures up to +120 degrees.
