Cylindrical Roller Bearings SKF N203 ECP

The N203 ECP cylindrical roller bearing from SKF Rolling Bearings, with a 17 mm bore, offers high radial load-carrying capacity as a compact idler bearing.

The N203 ECP cylindrical roller bearing is a single-row radial roller bearing with dimensions of 17x40x12 mm. In the N design, the inner ring guides the rollers between two fixed flanges, whilst the flangeless outer ring remains removable on both sides. An optimised internal design, together with the lightweight polyamide cage, contributes to favourable running characteristics under purely radial loads in industrial bearing arrangements.

In which applications does the N203 ECP cylindrical roller bearing act as a non-locating bearing?

This rolling bearing primarily functions as a non-locating bearing to accommodate purely radial forces. Thanks to the flangeless outer ring, the shaft compensates for axial length changes resulting from thermal expansion without constraint within the bearing. The design accommodates high radial forces at medium to high speeds. Its use is particularly recommended in shaft mountings where the axial guidance of the shaft is entirely provided by a separate fixed bearing.

What are the distinctive features of the N design and the polyamide cage?

The separability of the bearing simplifies assembly and maintenance procedures, as the inner ring and outer ring can be mounted independently of one another onto the shaft and housing. The elastic polyamide cage absorbs shock loads and is designed for a temperature range of –30 to +120 degrees Celsius. Thanks to dimensional accuracy to P0/PN (ABEC 1) and increased running accuracy to P6 (ABEC 3), smooth concentricity is ensured. As an open bearing, this design requires the selection of an application-specific lubricant and external housing sealing.
