Cylindrical Roller Bearings SKF NUP2212 ECP
The SKF NUP2212 ECP cylindrical roller bearing, with dimensions of 60x110x28 mm, provides precise radial support with a fixed-end function.
The NUP2212 ECP cylindrical roller bearing is a single-row roller bearing from SKF in the Explorer series, featuring an optimised internal design. Thanks to the line contact between the rollers and raceways, this design can withstand very high radial loads. With an inside diameter of 60 mm, an outside diameter of 110 mm and a width of 28 mm, the bearing is suitable for heavily loaded shafts in mechanical and plant engineering.
What is the NUP2212 ECP cylindrical roller bearing suitable for as a fixed bearing?
The NUP design features two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring. This enables the unit to accommodate not only prevailing radial forces but also axial guidance forces from both directions. Design engineers and maintenance personnel specifically use this design as a fixed bearing to precisely fix shafts axially whilst simultaneously supporting high radial loads with a compact installation width.
What advantages do the polyamide cage and the dimensional tolerances offer?
The polyamide cage guides the cylindrical rollers with low friction and ensures that the rotating parts within the bearing have a low weight. The permissible temperature range extends from –30 to +120 degrees Celsius. The dimensional accuracy corresponds to class P0 or ABEC 1, whilst the running accuracy is specified as P6 or ABEC 3. The open bearing without sealing washers requires application-specific lubrication and external housing sealing.
What are the dimensions of the NUP2212 ECP cylindrical roller bearing?
With an internal diameter of 60 mm, an external diameter of 110 mm and a width of 28 mm, this standardised size allows bearing units of the same dimensions to be fitted directly into existing structures.
What does the NUP design designation mean for this bearing?
As a fixed 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 design locks the shaft axially in both directions and, in addition to high radial forces, also transmits alternating axial guiding forces.
What are the key features of the polyamide cage?
The polyamide cage guides the rolling elements smoothly and quietly whilst minimising inertia. It reduces internal friction in the roller guide and is designed for operating temperatures ranging from -30 to +120 degrees Celsius. The material saves weight and dampens operational vibrations.
What are the bearing clearance and accuracy class?
Fitted with standard radial bearing clearance, this bearing is suitable for typical fit conditions and standard operating temperatures. The dimensional accuracy is P0 or ABEC 1, whilst the running accuracy corresponds to the finer tolerance class P6 or ABEC 3, which contributes to smooth concentricity.
How is the open cylindrical roller bearing lubricated?
In the open design without sealing washers, lubrication is provided via the surrounding housing structure. Depending on the speed and operating conditions, either grease or lubricating oil may be used. The outer ring has no groove and no lubrication bore, so lubricant must be supplied directly.
What are the key features of SKF’s Explorer range?
In the Explorer version, the bearing features an optimised internal design in which the raceways and roller surfaces are specifically matched to one another. This geometry reduces edge stresses under load and improves lubrication film behaviour, which enhances the load-carrying capacity of the bearing unit.
