Cylindrical Roller Bearings FAG NU2216 -E-XL-TVP2

The FAG NU2216 -E-XL-TVP2 cylindrical roller bearing, measuring 80 × 140 × 33 mm, is a floating bearing designed to accommodate high radial loads.

The FAG NU2216 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing designed to withstand high radial loads. Due to the line contact between the cylindrical rollers and the raceways, this design can withstand higher radial forces than ball bearings of the same dimensions. As an open bearing, this variant requires an external lubricant supply via the housing as well as protection against contamination. It is manufactured to tolerance class P0/PN (ABEC 1).

What is the NU2216 -E-XL-TVP2 cylindrical roller bearing suitable for?

This radial roller bearing serves as a non-locating bearing in shaft mountings subject to high radial forces and requiring axial length compensation. Due to the NU design, the inner ring has no flanges and can be axially displaced on both sides as well as removed completely. This enables the bearing to compensate for operational length changes in the shaft resulting from thermal expansion within the bearing. Furthermore, the separable design allows the inner and outer rings to be fitted separately onto the shaft and housing bore.

What function does the TVP2 polyamide cage fulfil in this application?

The designation TVP2 refers to a polyamide window cage which guides the cylindrical rollers and maintains a uniform spacing between them. Compared with solid metal cages, the lightweight polyamide material reduces inertial forces and promotes smooth running with low friction. Together with the standard radial bearing clearance, the bearing is designed for an operating temperature range of -30 to +120 degrees. When designing the housing, it must be taken into account that the outer ring is designed without a lubrication groove.
