Cylindrical Roller Bearings FAG NU217 -E-XL-TVP2

The FAG NU217 -E-XL-TVP2 cylindrical roller bearing, measuring 85x150x28 mm, offers high radial load-carrying capacity as a separable non-locating bearing with a lightweight polyamide cage.

The NU217 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for demanding industrial applications. With a bore of 85 mm, an outer diameter of 150 mm and a width of 28 mm, this roller bearing can accommodate significant radial forces. The design as a floating bearing allows for axial displacement of the shaft directly within the bearing. Design engineers and maintenance personnel opt for this design when rigid mountings cannot compensate for thermal length changes.

In which installation scenarios does the NU217 -E-XL-TVP2 cylindrical roller bearing prove its worth as a floating bearing?

This roller bearing is used where high radial forces are present and axial shaft expansion needs to be compensated for. As the inner ring has no flanges, the shaft moves freely relative to the outer ring when heated. This prevents axial stress in the bearing arrangement. As an open bearing, the unit can be flexibly integrated into on-site oil or grease lubrication systems, allowing the lubricant to be tailored directly to the ambient conditions.

What are the key features of the polyamide cage and the free-running bearing design?

The polyamide cage is characterised by its low weight and smooth running. The component is designed for a temperature range of -30 to +120 degrees. As the inner ring can be removed from both sides, the inner and outer rings can be mounted separately on the shaft and housing. This feature facilitates maintenance work and inspections. Manufacture to tolerance class P0 or ABEC 1 complies with standardised mounting dimensions.
