Spherical Roller Bearings SKF 23036 CCK/C4W33
The SKF 23036 CCK/C4W33 spherical roller bearing (180x280x74 mm) compensates for angular misalignment and withstands high radial loads at elevated operating temperatures.
The SKF 23036 CCK/C4W33 double-row self-aligning roller bearing is designed for demanding industrial applications involving high radial forces and simultaneous axial forces. With key dimensions of a 180 mm bore, 280 mm outside diameter and 74 mm width, this open bearing is suitable for heavy-duty machinery designs. Manufactured from standard rolling bearing steel (100Cr6), this rolling bearing operates within a temperature range of -30 to +200 °C. A robust sheet steel cage guides the symmetrical rollers and ensures even load distribution during operation.
What is the 23036 CCK/C4W33 self-aligning roller bearing suitable for?
The design reliably compensates for shaft deflection or misalignment between the inner and outer rings. Thanks to the hollow-spherical outer ring raceway, the roller set self-aligns without compromising the load-carrying capacity. Typical applications include heavy-duty drives and industrial gearboxes subject to combined loads or shock loads. Maintenance engineers use this design for direct replacement during servicing, whilst designers benefit from the standardised key dimensions.
What is the function of the C4 clearance and the tapered bore?
The suffix CCK/C4W33 identifies key design features for installation and operation. The tapered bore with a 1:12 taper allows mounting on a tapered shaft seat or using a clamping sleeve. During axial press-fitting, the bearing clearance is reduced, which is why the significantly increased radial bearing clearance C4 is selected. This reserve prevents seizing due to thermal expansion during operation at temperatures up to +200 °C. A lubrication groove with lubrication holes in the outer ring simplifies the relubrication of the raceways directly through the housing.
What are the dimensions of the 23036 CCK/C4W33 self-aligning roller bearing?
The bearing has a bore of 180 mm, an outer diameter of 280 mm and a width of 74 mm. It is made from standard roller bearing steel (100Cr6). Thanks to these standardised key dimensions, the bearing can be fitted precisely into suitable housings or, in the event of repairs, used as a replacement for bearing units of the same dimensions.
What does the bearing clearance C4 mean for this spherical roller bearing?
The designation C4 indicates a significantly increased radial bearing clearance, which exceeds both the standard operating clearance and that of C3. This increased clearance is required for tapered bearing seats, as the inner ring expands during axial pressing. Furthermore, C4 compensates for significant thermal expansion at operating temperatures of up to +200 °C.
How is the 23036 CCK/C4W33 spherical roller bearing lubricated?
The designation W33 refers to the integrated lubrication groove with holes in the outer ring. The lubricant reaches the space between the rows of rollers directly via these channels. As the roller bearing is of an open design, sealing is provided by the surrounding housing structure, whilst the relubrication system ensures a continuous supply of lubricant during operation.
Why does this self-aligning roller bearing have a tapered bore?
The tapered internal bore, designated by the letter K (1:12 taper), allows for secure mounting on stepped shafts or using suitable clamping and withdrawal sleeves. By moving the bearing axially along the tapered seat, fitters can precisely adjust the remaining bearing clearance. At the same time, this design makes disassembly considerably easier during subsequent maintenance work.
What is the bearing’s tolerance class?
This spherical roller bearing combines the dimensional accuracy of standard tolerance PN with increased running accuracy to Class P5. As a result, the external mounting dimensions remain easily compatible with standard housings, whilst the tighter concentricity tolerance contributes to smooth, low-vibration roller operation. This protects the shaft and drive components at high speeds.
What is the temperature range for which the bearing is specified?
The bearing is designed for a temperature range of -30 °C to +200 °C. Both the rolling-bearing steel and the sheet-steel cage can withstand these temperatures during continuous operation. During the design phase, it must be ensured that the external lubricants and the sealing elements used in the housing are also approved for these thermal conditions.
