SKF 22361 CC/W33 Spherical Roller Bearing | High Load Capacity & Misalignment Tolerance (d=305mm)

The SKF 22361 Spherical Roller Bearing (SRB) is engineered for exceptional performance in the most demanding industrial environments. Featuring two rows of rollers, a common spherical outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis, this high-capacity component is inherently self-aligning. This capability allows the bearing to compensate for both static and dynamic misalignment between the shaft and the housing, a critical requirement in large machinery operations. Manufactured using SKF's highest quality bearing steel, the 22361 ensures reliable operation, reduced internal friction, and superior resistance to wear under extreme radial and axial loads. Designed primarily for heavy-duty applications where shock loads and vibration are prevalent, the 22361 series significantly contributes to minimized operational downtime and extended service intervals. Typical applications include mining machinery, cement mills, heavy-duty fans, continuous casters, and large gearboxes. The optimized internal geometry, often including brass or reinforced steel cages (CC or CA suffixes), facilitates efficient lubricant distribution and maintains roller separation even at high operating temperatures. Investing in the SKF 22361 guarantees the precision, longevity, and predictable performance required to maintain operational efficiency in 24/7 industrial settings.

Key Features

• Inherent Self-Alignment: Compensates for significant shaft misalignment, reducing internal stress and increasing operational life.
• Extreme Load Capacity: Designed for very high radial and substantial axial loads in both directions.
• Low Friction Design: Optimized internal geometry minimizes heat generation and energy consumption.
• Extended Service Life: Manufactured with high-quality, ultra-clean SKF bearing steel for maximum durability.
• Robust Cage Structure: Features durable CC cage designs (steel or brass) suitable for high vibration and shock loads.
• Lubrication Groove (W33): Standard lubrication feature integrated into the outer ring for efficient maintenance and re-lubrication in situ.
