Spherical Roller Bearings SKF 23236 CC/W33

The SKF 23236 CC/W33 self-aligning roller bearing, with a 180 mm bore and P5 precision, offers high load-carrying capacity for demanding industrial applications.

The 23236 CC/W33 self-aligning roller bearing is an open roller bearing designed for heavy-duty industrial applications. Manufactured from standard bearing steel (100Cr6), it automatically compensates for misalignment and shaft deflection during operation. With an outer diameter of 320 mm and a width of 112 mm, the bearing can accommodate very high radial forces as well as combined axial loads in both directions. A sheet steel cage guides the symmetrical rollers at operating temperatures ranging from –30 to +200 degrees.

The internal design promotes even load distribution across the rolling elements, which reduces stress on the material under continuous loading.

What are the key operational characteristics of the 23236 CC/W33 self-aligning roller bearing?

Thanks to the hollow spherical raceway of the outer ring, this component accommodates misalignment between the shaft and housing without causing harmful edge stresses. The combination of standard radial clearance and increased P5 running accuracy is suitable for applications where precise guidance of the rotating inner ring is required. As the inner ring is fixed to the shaft, the precise running accuracy ensures smooth operation even under varying load conditions.

What is the function of the lubrication groove and lubrication holes according to W33?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This design facilitates the supply of lubricant during operation, as grease or lubricating oil is fed directly between the two rows of rollers. As an open bearing, this design has no factory-fitted seals. To ensure reliable operation, suitable seals must be fitted in the surrounding bearing housing to retain the lubricant within the bearing chamber and prevent the ingress of contaminants.
