Cylindrical Roller Bearings FAG NU2207 -E-XL-TVP2

The FAG NU2207 -E-XL-TVP2 single-row cylindrical roller bearing, with a 35 mm bore and an outer diameter of 72 mm, offers a high radial load capacity.

As a radial roller bearing, this unit can withstand high transverse forces. The cylindrical rollers create line contact with the raceway, giving the component high radial stiffness. The design is from FAG and has a width of 23 mm. Designed as an open bearing without an integrated seal, the unit is intended for an operating temperature range of –30 to +120 degrees Celsius.

What is the NU2207 -E-XL-TVP2 cylindrical roller bearing suitable for?

This design is primarily used in bearing arrangements where high radial loads must be supported and axial length changes in the shaft must be compensated for. Typical applications include industrial shaft bearings where thermal expansion occurs. As a non-locating bearing, the NU design does not absorb any axial forces. When the shaft expands thermally, the inner ring moves relative to the set of rollers in the outer ring, which helps to prevent axial stress in the overall system.

What are the distinctive features of the NU design and the polyamide cage?

The NU design is characterised by two solid flanges on the outer ring and a smooth, flangeless inner ring. The inner ring can be removed from both sides, which facilitates the separate assembly of the inner and outer rings. The polyamide cage guides the rolling elements whilst being lightweight itself. The bearing is manufactured to the standard tolerance class P0/PN (ABEC 1) and has the standard radial clearance. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied via the surrounding structure.
