Spherical Roller Bearings SKF 22236 CC/W33
The SKF 22236 CC/W33 self-aligning roller bearing, with dimensions of 180 × 320 × 86 mm, can accommodate high radial loads and reliably compensates for misalignment.
The SKF 22236 CC/W33 self-aligning roller bearing is designed for demanding industrial applications where heavy radial forces and additional axial forces are present. With a bore of 180 mm, an outside diameter of 320 mm and a width of 86 mm, this roller bearing provides stable support for heavy shafts. It is manufactured from standard roller bearing steel (100Cr6), and the standard radial clearance contributes to smooth running. Thanks to its open design, the bearing is suitable for systems with a centralised lubrication supply.
What is the 22236 CC/W33 self-aligning roller bearing suitable for?
This double-row roller bearing is used wherever high loads act on shafts and where operational deflections or misalignments need to be compensated for. The spherical raceway in the outer ring allows the roller sets to self-align angularly. Typical applications include heavy-duty gearboxes and large industrial drives. The integrated sheet steel cage guides the rolling elements with minimal vibration. Furthermore, the temperature range of –30 to +200 degrees allows for use in industrial environments subject to thermal stress.
What are the advantages of the W33 lubrication groove and tolerance class P5?
The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This feature facilitates relubrication, as the lubricant reaches directly between the rows of rollers and is distributed evenly. In addition to dimensional accuracy PN, this bearing features the enhanced running accuracy P5. A tighter running tolerance reduces runout error in rotating shafts, minimises vibrations and ensures smoother running. With the open design, designers must provide for external sealing of the housing.
What are the dimensions of the 22236 CC/W33 self-aligning roller bearing?
With an internal diameter of 180 mm, an external diameter of 320 mm and a width of 86 mm, the bearing determines the required installation space within the housing and the shaft seat. Before purchasing, you should check the mounting dimensions of the surrounding components.
What does the suffix W33 mean for this bearing?
The designation W33 indicates the presence of a lubrication groove and lubrication holes in the outer ring of the bearing. These channels allow grease or lubricating oil to be fed directly from the outside into the interior of the rolling element rows. This simplifies maintenance intervals and ensures a consistent supply to both rows of rollers during operation.
Why is tolerance class P5 important for this roller bearing?
The specification complies with PN standard dimensional accuracy and features P5-class running accuracy. The tighter P5 tolerance class reduces the radial and axial runout of the rings during rotation. This ensures precise guidance of the shaft and reduces bearing-induced vibrations in high-performance gearboxes.
What is the temperature range for which the bearing is designed?
The permissible temperature range is from -30 to +200 degrees. The dimensional stability of the 100Cr6 steel used is maintained within these limits. When selecting a lubricant, care must be taken to ensure that the chosen grease or industrial oil is approved for the relevant operating temperature.
Does the self-aligning roller bearing need to be sealed before fitting?
As an open bearing, this design does not have any integrated sealing washers. To prevent the ingress of dirt and moisture, as well as the leakage of lubricant, suitable housing seals must be fitted. Typically, labyrinth seals, V-rings or radial shaft seals are used on the bearing housing for this purpose.
What is the clearance in the 22236 spherical roller bearing?
The roller bearing is designed with standard radial clearance. This standard clearance is suitable for common fit designs on solid steel shafts where there are normal temperature differences between the inner and outer rings. For special applications involving significant heating or extreme press fits, it is recommended to consider variants with increased bearing clearance instead.
