Spherical Roller Bearings SKF 24132 CC/C4W33

Robust SKF 24132 CC/C4W33 self-aligning roller bearing, dimensions 160x270x109 mm, with significantly increased C4 clearance and W33 lubrication for demanding industrial applications.

The SKF 24132 CC/C4W33 self-aligning roller bearing accommodates high radial loads as well as combined axial loads and serves to compensate for shaft misalignment. With dimensions of 160 mm bore, 270 mm outer diameter and 109 mm width, this design is classified as a wide bearing for heavy loads. The manufacturer produces the bearing from standard 100Cr6 rolling-element bearing steel with a sheet steel cage. The open design, without integrated seals, allows for direct lubricant supply.

What loads and installation conditions can the 24132 CC/C4W33 self-aligning roller bearing accommodate?

This roller bearing is suitable for demanding applications involving high loads, where shaft deflection or misalignment between the bearing positions may occur. As the bearing is designed for operating temperatures ranging from -30 to +200 degrees, it is suitable for thermally demanding applications. The lubrication groove with lubrication holes in the outer ring (W33) allows lubricant to be replenished directly into the bearing interior whilst the bearing is in operation.

Why is the increased C4 bearing clearance important for this bearing?

The suffix C4 denotes a significantly increased radial bearing clearance, which exceeds the normal operating clearance and the C3 grade. This increased bearing clearance helps to prevent the rolling elements from becoming stressed when temperature differences arise between the inner and outer rings during operation. Together with the increased running accuracy to Class P5, combined with standard dimensional accuracy PN, the bearing ensures consistent concentricity even under mechanical and thermal stress.
