Deep Groove Ball Bearings SKF 6224

The SKF 6224 deep-groove ball bearing, measuring 120 × 215 × 40 mm, withstands high radial loads whilst featuring a compact, open design.

The SKF 6224 single-row deep groove ball bearing is designed to support rotating shafts under predominantly radial loads. Manufactured from standard 100Cr6 rolling bearing steel, this bearing offers high dimensional stability under load. The robust sheet steel cage guides the rolling elements evenly into the deep raceways. As this design is constructed without sealing washers, it is particularly suitable for assemblies with their own external lubrication supply.

What loads and mounting conditions can the 6224 deep-groove ball bearing accommodate?

The bearing reliably supports shafts with a diameter of 120 mm, primarily under radial load profiles. Due to its design, the deep groove geometry accommodates not only high radial forces but also moderate axial forces in both directions. This opens up a wide range of mounting options in industrial applications involving combined force transmission.

With a temperature range of –20 to +120 degrees, the component covers standard operating conditions in industrial environments. As the outer ring is cylindrical and has no flange or groove, the bearing can be fitted directly into smooth housing bores.

What are the advantages of the open design of the 6224 bearing?

The open design without sealing lips reduces the friction torque to the physical minimum. This results in lower friction losses at higher speeds. The bearing is usually integrated directly into enclosed housings with oil bath or recirculating lubrication, allowing the lubricant to dissipate heat and remove particles unimpeded.

Designed with standard radial bearing clearance and tolerance class P0 (ABEC 1), the bearing complies with current industry standards. The fit specifications for the shaft and housing bore are based on standardised basic tolerance grades. An external housing seal provides protection against contamination.
