Cylindrical Roller Bearings FAG NUP2209 -E-XL-TVP2
The NUP2209 -E-XL-TVP2 cylindrical roller bearing (45 x 85 x 23 mm) serves as a single-row fixed bearing designed to accommodate high radial loads and provide axial guidance on both sides.
The NUP2209 -E-XL-TVP2 cylindrical roller bearing from FAG is a single-row rolling bearing with a 45 mm bore, an 85 mm outer diameter and a width of 23 mm. As an open component without sealing washers, it is designed for operation in oil- or grease-lubricated housings. The bearing has standard radial clearance and a tolerance class of P0 (ABEC 1). The cylindrical rolling elements transmit high radial forces in industrial applications.
What is the NUP2209 -E-XL-TVP2 cylindrical roller bearing suitable for as a fixed bearing?
The NUP design serves as a fixed bearing: two fixed flanges on the outer ring, together with one fixed flange and one loose flange disc on the inner ring, guide the shaft axially on both sides. This arrangement is used in bearing arrangements where high radial forces are present and axial displacement must be limited in both directions. As the outer ring is manufactured without a groove or lubrication bore, the lubricant reaches the roller tracks directly via the open end face.
What are the key features of the TVP2 polyamide cage?
The suffix TVP2 denotes a polyamide cage that maintains a uniform spacing between the cylindrical rollers. The material contributes to a low cage weight and smooth running. The component is designed for a temperature range of -30 to +120 degrees. The open bearing requires a clean environment and a suitable lubricant supply within the housing.
What does the NUP design designation mean in the case of the NUP2209 cylindrical roller bearing?
The NUP design denotes a fixed bearing. The outer ring has two fixed flanges, whilst the inner ring has one fixed flange and one loose flange disc. This enables the bearing to absorb radial forces and also guide the shaft in both axial directions within the housing.
What are the dimensions of the NUP2209 -E-XL-TVP2 cylindrical roller bearing?
The bearing has an inside diameter of 45 mm, an outside diameter of 85 mm and a width across flats of 23 mm. These dimensions comply with the standardised metric 2209 series. The single-row radial roller bearing is designed as an open type without a lubrication groove on the outer ring.
What temperature range is the bearing suitable for?
The permissible temperature range is from -30 to +120 degrees. This range is limited, amongst other things, by the polyamide cage fitted and the thermal resistance of the lubricant used. Applications outside this temperature range require specially adapted materials.
What does the tolerance class P0 or ABEC 1 mean?
Tolerance class P0 (equivalent to PN or ABEC 1) defines the standard dimensional and running tolerances for rolling bearings in accordance with the ISO standard. Bearings in this accuracy class are suitable for standard applications in mechanical engineering with standard requirements for dimensional accuracy.
What is the clearance of the NUP2209 cylindrical roller bearing?
This bearing has standard radial clearance. The radial clearance between the rollers and the raceways is dimensioned such that, with standard fit selections for the shaft and housing, as well as heat generated during operation, perfect concentricity is ensured.
Why is an external seal required for this open cylindrical roller bearing?
As the bearing is designed as an open type without integrated seals, the raceways and rollers are exposed. The bearing housing must be protected from dirt and moisture by means of shaft seals or labyrinth seals fitted to the surrounding casing, in order to prevent premature wear caused by foreign particles.
