Cylindrical Roller Bearings FAG NU211 -E-XL-TVP2

The NU211 -E-XL-TVP2 cylindrical roller bearing from FAG, measuring 55x100x21 mm, offers high radial load-carrying capacity as a separable idler bearing for demanding industrial applications.

The NU211 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG Wälzlager with a cylindrical bore. With a bore of 55 mm, an outer diameter of 100 mm and a width of 21 mm, this design is primarily designed to withstand high radial loads. As an open bearing, it can be flexibly integrated into existing lubrication systems. It is manufactured to tolerance class P0/PN or ABEC 1, meaning the bearing meets the standard for industrial mechanical engineering.

When is the NU211 -E-XL-TVP2 design recommended?

This version is primarily used where bearings need to compensate for thermal length changes in the shaft. As the NU design is conceived as a pure non-locating bearing, the inner ring has no flanges and can be removed from either side. Axial movements occur freely within the raceway between the rollers and the ring. It is primarily used in shaft bearings where precise radial guidance is required and axial forces are supported separately by a fixed bearing.

What advantages does the TVP2 polyamide cage offer in this bearing?

The suffix TVP2 denotes a polyamide cage that precisely guides the cylindrical rollers. The material dampens running noise and reduces friction during operation. When using this bearing, the permissible temperature range of –30 to +120 degrees must be taken into account, as plastics are more sensitive to overheating than metallic materials. The bearing has a standard radial clearance, which promotes stable concentricity at normal operating temperatures and with standard shaft fits.

What are the key features of the NU211 -E-XL-TVP2 cylindrical roller bearing?

A single-row radial roller bearing with an inner diameter of 55 mm, an outer diameter of 100 mm and a width of 21 mm. It is of the NU design with a flangeless inner ring, which enables it to accommodate axial shaft displacement as a pure support bearing. An integrated polyamide cage keeps the rolling elements spaced apart and ensures quiet operation.

What are the dimensions of the NU211 -E-XL-TVP2 cylindrical roller bearing?

This bearing has a bore of 55 mm, an outside diameter of 100 mm and a width of 21 mm. The outer ring is designed without a lubrication groove or lubrication bore. Thanks to its dimensions, which comply with tolerance class P0 or ABEC 1, the component fits precisely into corresponding bearing seats in mechanical engineering applications.

Why is the inner ring removable in the NU design?

The NU design features two fixed shoulders on the outer ring, whilst the inner ring is ground without shoulders. This allows the inner ring to be pulled out axially from either end. This separability facilitates both the separate mounting of the inner and outer rings onto the shaft and housing, and the inspection of the bearing housing.

What is the function of the TVP2 cage in the bearing?

The abbreviation TVP2 refers to a polyamide cage. This material reduces the rotating masses within the roller bearing and guides the cylindrical rollers with low friction. It contributes to good noise damping. During operation, the permissible temperature range of -30 to +120 degrees must be observed in order to protect the material.

What type of lubrication does the open cylindrical roller bearing require?

As an open bearing, this variant does not have any integrated sealing washers. Before commissioning, apply a suitable lubricating oil or rolling-element bearing grease to the bearing seat. The surrounding housing design requires external seals to ensure that the lubricant remains within the bearing chamber and that no contaminants reach the raceways.

What does the specification for the standard radial bearing clearance mean?

This marking indicates that the radial clearance in the bearing complies with the standard specifications. The design clearance between the rollers and raceways compensates for operational heating and fitting allowances during installation. Under normal operating conditions, the standard bearing clearance ensures smooth running without excessive preload.
