Spherical Roller Bearings SKF 22230 CCK/W33

The SKF 22230 CCK/W33 self-aligning roller bearing accommodates high radial loads with a bore diameter of 150 mm and reliably compensates for misalignment during operation.

The SKF 22230 CCK/W33 self-aligning roller bearing is designed for demanding industrial applications involving combined loads. Thanks to its double-row barrel rollers, the bearing automatically compensates for static and dynamic angular misalignment and shaft deflection. The design, made from standard 100Cr6 rolling-element bearing steel, operates reliably within a temperature range of –30 to +200 degrees Celsius. As an Explorer version, the open bearing combines standardised dimensional accuracy in accordance with PN with enhanced running accuracy in accordance with tolerance class P5.

Under what loads does the 22230 CCK/W33 self-aligning roller bearing prove its worth?

This self-aligning roller bearing is primarily used where high radial forces act on heavy shafts and where operational misalignment may occur. Typical applications include general mechanical engineering, conveyor systems, industrial gearboxes and heavy-duty drives. As the bearing is open at both ends, it can be flexibly integrated into housing systems with external sealing and a central lubrication supply.

What installation advantages does the tapered bore of the 22230 CCK/W33 offer?

The design with a tapered bore with a taper ratio of 1:12 enables precise mounting directly onto tapered shaft seats or using suitable clamping and withdrawal sleeves. The remaining radial bearing clearance can be precisely adjusted during assembly via the axial slide-on travel. The roller-guided sheet steel cage guides the rolling elements stably, whilst the lubrication groove integrated into the outer ring, with its lubrication holes, ensures a uniform supply of grease or lubricating oil during operation.
