Cylindrical Roller Bearings SKF NJ2212 ECP

The SKF NJ2212 ECP cylindrical roller bearing, with dimensions of 60x110x28 mm, offers a high radial load capacity as well as axial guidance in one direction.

The SKF NJ2212 ECP cylindrical roller bearing is a single-row rolling bearing with an optimised internal design in the Explorer performance class. It primarily accommodates high radial loads and provides single-sided axial guidance for shafts. With a bore of 60 mm, an outside diameter of 110 mm and a width of 28 mm, the design is suitable for demanding bearing arrangements in mechanical engineering. The combination of a polyamide cage and standard radial clearance ensures smooth running within an operating temperature range of –30 to +120 degrees.

What is the NJ2212 ECP cylindrical roller bearing suitable for as a support bearing?

This design is primarily used in bearing arrangements where significant radial loads are present and axial length changes may occur. Due to the NJ design, the bearing functions as a support bearing. The outer ring has two fixed flanges, whilst the inner ring has one fixed flange and remains removable on one side. This enables the bearing to compensate for axial length changes of the shaft in one direction and to support axial forces from the opposite direction. This also simplifies the separate installation of both bearing rings.

What are the key features of the cage and design of the NJ2212 ECP?

The ECP-type polyamide cage reduces friction within the bearing and enables smooth running whilst keeping the weight low. In the SKF Explorer design, the optimised internal geometry ensures favourable stress distribution across the raceways. With dimensional accuracy to P0 or ABEC 1 and increased running accuracy to P6 or ABEC 3, the bearing meets high industrial specifications. As this is an open bearing without an integrated seal, you should adapt the lubrication and housing sealing to the operating environment.
