Cylindrical Roller Bearings FAG N211 -E-XL-TVP2

The FAG N211 -E-XL-TVP2 cylindrical roller bearing is a single-row idler bearing with a polyamide cage, measuring 55 x 100 x 21 mm.

As a radial roller bearing, the N211 -E-XL-TVP2 cylindrical roller bearing can accommodate high radial loads. Thanks to the cylindrical rollers, this design provides line contact along the raceways, giving the bearing high radial stiffness. This open bearing from FAG Rolling Bearings has a bore of 55 mm, an outer diameter of 100 mm and a width of 21 mm. It is suitable for operating temperatures ranging from -30 to +120 degrees.

In which bearing arrangements is the N211 -E-XL-TVP2 cylindrical roller bearing used?

This cylindrical roller bearing is primarily used as a non-locating bearing for shaft guides subjected to purely radial loads. As the outer ring is designed to be removable on both sides and has no flanges, the bearing allows axial length changes of the shaft to be accommodated without constraint within the rolling elements. Shaft mountings utilise this degree of freedom to compensate for thermal expansion without inducing stress. The separable design also facilitates the separate installation of the inner and outer rings.

What does the N design with a polyamide cage mean for the design?

The N design is characterised by two fixed flanges on the inner ring and a flangeless outer ring. The polyamide cage ensures quiet guidance of the single row of rollers and reduces friction within the bearing. Manufactured to standard tolerances (tolerance class P0/PN or ABEC 1) and with standard radial clearance, the component fits precisely into standardised bearing seats. As the outer ring has no groove or lubrication bore and the bearing is open, provision must be made for lubricant supply and external housing seals in the surrounding structure.
