Spherical Roller Bearings SKF 22330 CC/W33

The SKF 22330 CC/W33 open self-aligning roller bearing (150x320x108 mm) compensates for misalignment and accommodates heavy radial and axial loads in mechanical engineering.

The SKF 22330 CC/W33 self-aligning roller bearing is a double-row roller bearing designed for heavy-duty industrial applications involving combined loads. Thanks to the hollow-spherical outer ring raceway, the bearing adjusts with angular movement, thereby compensating for shaft deflection and misalignment. The design, made from standard rolling-element bearing steel (100Cr6), features a robust sheet steel cage and operates within a temperature range of -30 to +200 degrees. As an Explorer version, this open bearing is characterised by optimised surfaces and high-quality rolling-element bearing steel.

What is the 22330 CC/W33 self-aligning roller bearing suitable for?

Typical applications include heavy-duty mechanical engineering and industrial shaft mountings subject to high loads. The bearing is suitable for applications where high radial forces are combined with axial forces on both sides. Thanks to its open design, the bearing can be integrated directly into enclosed housings. In the event of shaft deflection under load, the internal design counteracts harmful edge stresses on the rolling elements, thereby promoting smooth running.

What role do the W33 lubrication groove and tolerance class P5 play?

The suffix W33 denotes a lubrication groove with lubrication holes in the outer ring, which simplifies targeted relubrication directly into the bearing interior. The tolerance class combines normal dimensional accuracy (PN) with increased running accuracy in accordance with Class P5. This minimises runout errors, which reduces vibrations at higher speeds. Featuring standard radial bearing clearance, the bearing is particularly suitable for standard fit combinations without significant temperature differences between the inner and outer rings.
