Cylindrical Roller Bearings FAG NUP2317 -E-XL-TVP2

The NUP2317 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager combines an 85 mm bore with a fixed-end function and a polyamide cage for high radial loads.

The NUP2317 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing from FAG Wälzlager with a bore of 85 mm, an outer diameter of 180 mm and a width of 60 mm. Thanks to the line contact of the cylindrical rolling elements, the bearing can withstand high radial forces. In the NUP version, the unit has two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring, enabling it to function as a fixed bearing.

What is the NUP2317 -E-XL-TVP2 cylindrical roller bearing suitable for in operation?

Design engineers and maintenance personnel primarily use this design in bearing arrangements where, in addition to high radial forces, alternating axial loads from both directions occur. Typical applications include shaft mountings subject to combined loads in industrial drives. The single-row roller bearing guides the shaft axially via a positive fit and limits axial play, whilst the cylindrical rollers simultaneously ensure high radial stiffness.

What are the advantages of combining a polyamide cage with the NUP design?

The integrated polyamide cage guides the cylindrical rollers and ensures low-friction and low-noise operation. Compared with solid metal cages, the lightweight plastic material reduces the mass of the rolling element set. As this is an open bearing without an integrated seal, users can select the lubricant and external housing seal to suit the specific operating environment. With normal radial bearing clearance, the design covers a temperature range from -30 to +120 degrees.
