Spherical Roller Bearings SKF 23038 CC/W33

The 23038 CC/W33 spherical roller bearing from SKF offers, with dimensions of 190x290x75 mm, a high load-carrying capacity for heavy radial loads in mechanical engineering.

The 23038 CC/W33 self-aligning roller bearing is an open roller bearing designed for demanding industrial applications. With an inner diameter of 190 mm, an outer diameter of 290 mm and a width of 75 mm, this component withstands heavy radial and axial forces on both sides. Thanks to its spherical rollers, the bearing automatically compensates for misalignment and shaft deflection during operation. The manufacturer, SKF Rolling Bearings, produces this unit from conventional standard rolling bearing steel (100Cr6).

What loads does the 23038 CC/W33 self-aligning roller bearing withstand during operation?

Design engineers select the 23038 CC/W33 self-aligning roller bearing primarily for heavy-duty shaft mountings where misalignment or elastic deformation occurs. Typical applications are found in industrial plant subject to high impact and continuous loads. The component automatically compensates for misalignment between the inner and outer rings during operation. A sheet steel cage guides the rolling elements, whilst the permissible temperature range of –30 to +200 degrees covers a wide range of thermal operating conditions.

What are the advantages of the lubrication groove and P5 running accuracy?

The designation W33 indicates an annular lubrication groove with lubrication holes in the outer ring. This design facilitates the supply of lubricant directly into the bearing interior and facilitates relubrication whilst the bearing is installed. With this open bearing, you can tailor the lubricant precisely to your operating conditions. In addition to PN dimensional accuracy, this design is characterised by P5 running accuracy, which promotes uniform concentricity under normal radial bearing clearance.
