Cylindrical Roller Bearings SKF NU306 ECP

The SKF NU306 ECP cylindrical roller bearing (30x72x19 mm) is a single-row idler bearing that withstands high radial loads and compensates for axial length changes with low friction.

The SKF NU306 ECP cylindrical roller bearing is designed for demanding industrial applications involving purely radial loads. Thanks to its SKF Explorer quality design, the bearing features an optimised internal structure that improves roller contact. With a bore of 30 mm, an outside diameter of 72 mm and a width of 19 mm, the component fits precisely into standardised housing dimensions. You receive a reliable component for both design and maintenance.

In which bearing arrangements is the NU306 ECP cylindrical roller bearing used?

This single-row roller bearing is primarily used as a conventional non-locating bearing in shaft mountings subject to thermal linear expansion. Typical applications include industrial drives and rotating machine shafts subjected to high radial forces. As the outer ring has two fixed flanges and the inner ring is flangeless, the shaft and housing can move axially relative to one another. This prevents stress build-up in the shaft train and ensures smooth machine operation.

What are the functions of the NU design and the ECP cage?

The NU design is characterised by an inner ring that can be removed from both sides. This feature makes installation and maintenance considerably easier, as the inner and outer rings can be fitted separately. The integrated polyamide cage (designation suffix ECP) ensures precise guidance of the cylindrical rollers whilst maintaining a low weight. The open bearing has standard radial clearance and is designed for a temperature range of -30 to +120 degrees. External seals protect the raceways from contamination.
