Cylindrical Roller Bearings SKF N226 ECP

The SKF N226 ECP cylindrical roller bearing, a single-row non-locating bearing measuring 130 × 230 × 40 mm, offers high radial load-carrying capacity in a compact design.

The N226 ECP cylindrical roller bearing is an open, single-row rolling bearing for industrial applications subject to purely radial loads. With a bore of 130 mm, an outer diameter of 230 mm and a width of 40 mm, the bearing can withstand considerable forces. The manufacturer, SKF, produces this version in the Explorer class with an optimised internal design. The roller bearing is designed for demanding shaft mountings where radial guidance is the primary requirement.

In which installation situations is the N226 ECP cylindrical roller bearing used?

This cylindrical roller bearing is particularly suitable for bearing arrangements where high radial forces occur and axial length changes in the shaft must be compensated for. As a floating bearing with an outer ring that can be removed from both sides, it does not guide the shaft axially but allows for axial displacement within the bearing. Typical applications include bearing arrangements subject to high radial forces and temperature-induced shaft expansion. The N design also allows for separate assembly of the inner and outer rings, which facilitates installation.

What are the key features of the polyamide cage and the tolerances?

The integrated polyamide cage reduces the weight of the rotating parts and promotes smooth, low-vibration operation. The N design is characterised by two solid flanges on the inner ring, whilst the outer ring has no flanges. This allows both bearing rings to be mounted separately onto the shaft and into the housing. The bearing is designed for operating temperatures ranging from -30 to +120 degrees. With dimensional accuracy to P0/PN (ABEC 1) and running accuracy to P6 (ABEC 3), this design also meets precise concentricity requirements.
