Cylindrical Roller Bearings FAG NUP307 -E-XL-TVP2-C3

The FAG NUP307 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 35x80x21 mm, offers high radial load-carrying capacity and axial guidance when used as a fixed bearing.

The NUP307 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing manufactured by FAG. Thanks to the line contact between the rollers and raceways, this design can accommodate very high radial loads. As a fixed bearing in the NUP series, this version features fixed flanges and a loose flange disc. Consequently, the design guides a shaft axially in both directions. With a bore diameter of 35 mm, an outer diameter of 80 mm and a width of 21 mm, the bearing complies with standardised key dimensions.

When is the NUP307 -E-XL-TVP2-C3 cylindrical roller bearing recommended as a fixed bearing?

This design is used when rolling bearings are subjected to high radial loads and, at the same time, the shaft needs to be axially fixed at both ends. Thanks to the open design without an integrated seal, lubricant can reach the rolling elements and raceways unhindered. The outer ring is designed without a lubrication groove, which is why lubricant is supplied via the housing environment or the inner ring.

What is the function of the polyamide cage and the C3 clearance?

The designation TVP2 denotes a solid polyamide cage, which ensures smooth running and reduces the weight of the moving parts. The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance compensates for thermal expansion during operation or fit allowances on the shaft and housing. The component is suitable for a permissible temperature range of -30 to +120 degrees.
