Deep Groove Ball Bearings SKF 6322 /C3

The SKF 6322 /C3 deep groove ball bearing is an open rolling bearing with a 110 mm bore, a 240 mm outer diameter and an increased clearance (C3).

This single-row deep-groove ball bearing 6322/C3 from SKF is designed primarily to accommodate radial loads as well as axial forces in both directions. Manufactured from standard 100Cr6 rolling bearing steel, this design features a robust sheet steel cage that guides the rolling elements. As it is an open bearing without integrated sealing washers, lubricant reaches the raceways unimpeded. The component is designed for an operating temperature range of –20 to +150 degrees Celsius and is suitable for demanding industrial drives.

Under what operating conditions is the 6322 /C3 deep-groove ball bearing with C3 clearance required?

Design engineers select the 6322 /C3 deep groove ball bearing for heavy-duty shaft mountings subject to increased thermal stress. The increased clearance (C3) compensates for thermal expansion caused by the shaft or housing heating up. Furthermore, this radial clearance compensates for the narrowing of the inner ring caused by tight fits. This ensures that rotational movement remains smooth even when there are temperature differences between the rotating shaft and the housing.

What are the advantages of combining an open design with C3 clearance?

The open design, without a flange or groove on the outer ring, facilitates integration into existing oil or grease lubrication systems. You can select the type of lubricant and lubrication intervals to suit the operating conditions of your plant. When designing the system, ensure that the bearing housing is externally sealed against dust and moisture. With tolerance class P0/PN or ABEC 1, the bearing meets standard industrial precision requirements for smooth running.
