Cylindrical Roller Bearings SKF NUP226 ECJ

The SKF NUP226 ECJ cylindrical roller bearing is a single-row fixed bearing with main dimensions of 130 × 230 × 40 mm, designed for high radial loads.

As a single-row roller bearing, the SKF NUP226 ECJ cylindrical roller bearing withstands high radial forces and supports shafts axially in both directions. With key dimensions of a 130 mm bore, 230 mm outside diameter and 40 mm width, this design is suitable for use as a fixed bearing in heavy machinery. The optimised internal design of the Explorer series reduces friction at the roller end faces and flanges. This promotes even load distribution during operation and contributes to smooth running.

What is the NUP226 ECJ cylindrical roller bearing suitable for as a fixed bearing?

This cylindrical roller bearing is primarily used where high radial loads must be supported and axial displacement of the shaft must be limited. With two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange disc, the NUP design secures the shaft on both sides in the axial direction. Typical applications include gearbox mountings and heavy-duty shaft guides in mechanical engineering, where defined axial guidance and a high load-carrying capacity are required.

What are the characteristics of the sheet steel cage and the Explorer design?

The sheet steel cage keeps the cylindrical rollers spaced apart and keeps the weight low compared to solid cages. In the Explorer version, the bearing is characterised by an optimised internal design. The component features dimensional accuracy to P0/PN (ABEC 1) and tighter running accuracy to tolerance class P6 (ABEC 3). For use in sealed housings with an external lubricant supply, the open design covers a temperature range from -30 to +150 degrees.
