Cylindrical Roller Bearings FAG NU306 -E-XL-TVP2-C3

The FAG NU306 -E-XL-TVP2-C3 cylindrical roller bearing, as an open idler bearing with dimensions of 30x72x19 mm, can accommodate high radial loads.

This single-row cylindrical roller bearing, NU306 -E-XL-TVP2-C3, is designed purely as a support bearing. Thanks to the line contact of the cylindrical rollers, this design can withstand high radial forces. The inner ring has no flanges and can be removed from both sides, which facilitates the separate assembly of the inner and outer rings. FAG manufactures this rolling bearing in the standard tolerance class P0/PN (corresponding to ABEC 1) for use in industrial mechanical engineering.

When is the NU306 -E-XL-TVP2-C3 cylindrical roller bearing used?

The NU design is primarily intended to compensate for axial length changes in rotating shafts within the bearing itself without any binding. Typical applications include shaft mountings where high radial forces are present and thermal linear expansion may occur. As the inner ring has no flanges, the shaft moves axially relative to the outer ring without any axial stresses being exerted on the bearing assembly.

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

The suffix TVP2 denotes a solid polyamide cage, which ensures quiet running and low friction. The permissible temperature range is from –30 to +120 degrees. The designation C3 indicates a slightly increased radial bearing clearance. This additional clearance compensates for operational heating or tight fits, ensuring that the rolling bearing does not seize radially during operation.
