The SKF NUP2205 ECP cylindrical roller bearing, as a single-row fixed bearing, accommodates high radial loads and axial forces within a 25x52x18 mm installation space.
This single-row cylindrical roller bearing, the NUP2205 ECP, is characterised by its optimised internal design in the SKF Explorer version. With a bore diameter of 25 mm, an outside diameter of 52 mm and a width of 18 mm, this open bearing is suitable for designs with an external lubrication supply. It combines dimensional accuracy to standard tolerance (P0/PN or ABEC 1) with enhanced running accuracy of class P6 (ABEC 3).
Design engineers and maintenance technicians use this bearing in industrial applications where high radial forces act on the shaft. Thanks to the NUP design, the bearing assembly simultaneously provides axial guidance for the shaft in both directions. As cylindrical rollers have line contact with the raceways, the component is specifically designed for high radial loads.
The integrated polyamide cage guides the rollers quietly and reduces the component’s weight compared to solid metal cages. The component features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring, enabling it to function as a true fixed bearing. The permissible operating temperature range is from –30 to +120 degrees Celsius. Under normal operating conditions, the standard radial bearing clearance contributes to smooth running.
The bearing has an internal diameter of 25 mm, an external diameter of 52 mm and a width of 18 mm. Before fitting, check the available installation space and the shaft diameter at your bearing location to ensure a precise fit.
The designation NUP denotes a fixed bearing. The outer ring has two fixed guide flanges, whilst the inner ring has one fixed flange and one loose flange disc. This enables the bearing to withstand high radial loads whilst simultaneously fixing the shaft in both axial directions.
The suffix ECP indicates a polyamide cage. This type of cage is characterised by low friction, elastic behaviour under impact loads and a low moment of inertia. It is designed for operating temperatures ranging from -30 to +120 degrees Celsius and ensures low-vibration operation of the rollers.
With this product, the manufacturer combines the standard dimensional tolerance P0 (ABEC 1) with increased running accuracy in accordance with Class P6 (ABEC 3). This results in tighter concentricity tolerances for the outer and inner rings. Consequently, the bearing runs more smoothly, which helps to reduce vibration in precision machine drives.
No, this is an open bearing without integrated sealing washers. The lubricant reaches the rolling elements directly, which is why the bearing housing must be protected against the ingress of dirt and moisture by means of an external housing seal. Lubrication can be carried out using either grease or circulating oil.
The component has a standard radial bearing clearance (CN). This standard value is suitable for typical industrial applications where conventional fits are selected for the shaft and housing. Under normal thermal operating conditions, this results in neither excessive preload nor excessive radial clearance.
