SKF 22336 CCJA/W33VA406 180x380x126 mm Spherical Roller Bearing

Applications & Industrial Use

The SKF 22336 CCJA/W33VA406 is designed for demanding industrial applications where combined radial and axial loads, shaft deflections and operating misalignments are expected. With key dimensions of 180 mm inner diameter (d), 380 mm outer diameter (D) and 126 mm width (B) it fits large-scale bearing housing units and bearing assemblies used in heavy machinery, conveyors, crushers, gearboxes and vibrating equipment. It is a robust bearing unit that supports “industrial applications”, “bearing housing”, “bearing unit heavy duty” and “high durability” demands. According to SKF data it is part of the 223 series for vibratory applications with features for enhanced service life.
In procurement search behaviour the following keywords emerge: “spherical roller bearing 22336”, “SKF 22336 CCJA/W33VA406”, “bearing 180x380x126”, “heavy duty spherical roller bearing”, “industrial bearing housing bearing unit”.

Key Advantages & Technical Features

• Self-aligning spherical roller design compensates for misalignment between shaft and housing, reducing risk of premature failure in “bearing housing” applications.

• The “CCJA/W33VA406” suffix indicates: CC heavy-duty design, JA centred guide ring in outer ring, W33 lubrication groove and three oil holes, VA406 PTFE-coated bore variant for vibratory or harsh environments.

• With the dynamic load rating and dimensions provided by SKF (bore: 180 mm, outer diameter: 380 mm, width: 126 mm) this bearing supports very high radial and axial loads and fits bearing housing units of large scale.

• Ideal for systems requiring “high durability”, “industrial applications”, “bearing housing unit”, “obudowa łożyskowa” - particularly in sectors such as mining, processing plants, heavy conveyors and large drive systems.

FAQ

Q1: What distinguishes a spherical roller bearing from a standard ball bearing?
A: A spherical roller bearing features two rows of rollers and a self-aligning outer ring, enabling it to accommodate significant radial loads, moderate axial loads in both directions, as well as shaft misalignment or housing deformation. In contrast, standard ball bearings handle primarily radial loads and small axial loads and require precise alignment.

Q2: What does the suffix “CCJA/W33VA406” indicate?
A: In the SKF designation, “CC” points to heavy-duty series, “JA” indicates a centred guide ring in the outer ring, “W33” refers to an oil groove and three lubrication holes in the outer ring, and “VA406” designates a PTFE-coated bore version optimized for vibratory environments and high fatigue resistance.

Q3: Can this bearing be used in bearing housing units?
A: Yes. With dimensions 180x380x126 mm and robust design, the 22336 CCJA/W33VA406 is specifically suited for use in bearing housing arrangements (units) in heavy industrial machinery and supports the search terms “bearing housing”, “housing unit heavy duty”.

Q4: What maintenance considerations apply for this bearing in heavy applications?
A: Use of correct lubrication is critical—version W33 provides built-in lubrication groove and holes. Monitoring for cleanliness, alignment and load conditions is recommended. For high vibration or misalignment environments, ensure the bearing is mounted in a suitable housing with correct clearance and support as detailed in manufacturer literature.

Q5: Why should a B2B buyer choose this model?
A: For industrial buyers, the 22336 CCJA/W33VA406 delivers high load capacity, long service life, resistance to misalignment and suitability for heavy duty applications. This reduces downtime, supports reliability, and simplifies integration in bearing housing units — making it a strong choice for procurement of robust components.
