Cylindrical Roller Bearings SKF NUP2206 ECP/C3
The SKF NUP2206 ECP/C3 cylindrical roller bearing is a single-row fixed bearing that combines high radial load-carrying capacity with axial shaft guidance on both sides, whilst maintaining compact dimensions of 30 × 62 × 20 mm.
The SKF NUP2206 ECP/C3 cylindrical roller bearing is a single-row rolling bearing with an optimised internal design. It accommodates high radial loads and guides the shaft in both axial directions via two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. With key dimensions of a 30 mm bore, 62 mm outer diameter and 20 mm width, this open design is suitable for installation in enclosed housing constructions with an existing lubrication supply.
What is the NUP2206 ECP/C3 cylindrical roller bearing suitable for as a fixed bearing?
The NUP design is recommended for applications where high radial forces are combined with axial positioning of the shaft on both sides. The bearing acts as a fully-fledged fixed bearing without the need for additional axial support components. As this is an open design without an integrated seal and without a lubrication bore in the outer ring, the lubricant is supplied via the surrounding housing structure.
What is the function of the polyamide cage and the C3 clearance?
The ECP design features a lightweight polyamide cage, which ensures smooth running and reduces friction within the rolling element set. The increased radial clearance (C3) compensates for thermal expansion during operation when temperature differences arise between the shaft and the housing. The bearing is suitable for a temperature range of -30 to +120 degrees. The tolerance class offers dimensional accuracy to P0 or ABEC 1 and running accuracy to P6 or ABEC 3.
What are the distinctive features of the NUP design in the NUP2206 ECP/C3 cylindrical roller bearing?
The NUP design features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. This enables the bearing to absorb radial forces whilst simultaneously fixing the shaft in both axial directions, making it a classic fixed bearing.
What are the dimensions of the NUP2206 ECP/C3 cylindrical roller bearing?
This cylindrical roller bearing has an inside diameter of 30 mm, an outside diameter of 62 mm and a width of 20 mm. These dimensions correspond to the standardised main dimensions of the 2206 series and enable the bearing seat to be designed with precision.
What does the ‘C3’ designation mean in relation to bearing clearance?
The suffix C3 indicates a radial bearing clearance that is slightly greater than that of standard bearings. This additional clearance helps to prevent the rolling elements from becoming stressed when tight fits or operational heating of the shaft and housing reduce the radial clearance.
What is the approved temperature range for the bearing?
The permissible operating range is between -30 and +120 degrees. In addition to the lubricant, the main limiting factor here is the polyamide cage, whose material properties are designed for this temperature range.
How is the NUP2206 ECP/C3 cylindrical roller bearing sealed?
The cylindrical roller bearing is designed as an open rolling bearing without integrated seals. Protection against contamination and the retention of the lubricant are provided by external sealing elements in the surrounding housing structure.
What are the bearing’s tolerance classes?
The component combines two tolerance grades: dimensional accuracy complies with standard class P0 or ABEC 1, whilst running accuracy is to the tighter tolerance class P6 or ABEC 3. This ensures smooth, low-vibration concentricity.
