SKF SPHERICAL ROLLER BEARING 22348CC/W33

This spherical roller bearing from SKF is designed to accommodate high radial and axial loads and ensures smooth and stable operation. Thanks to its self-aligning capability and robust construction, it reliably compensates for misalignment and shaft deflection. It is notable for its high reliability in applications with dynamic loads and high speeds.

Features:
This two-row roller bearing is equipped with two pressed-steel window-type cages, has an inner ring without shoulders and a freely guided locating ring that is centered on the inner ring. The cylindrical bore allows direct mounting on the shaft, which significantly simplifies installation. Its lightweight yet durable cages ensure an even distribution of radial and axial loads in both directions. The standard radial clearance supports a balanced mechanical response even at high speeds. The open design without seals reduces friction and improves overall efficiency. This enables high speeds while minimizing the risk of overheating.

Maintenance:
Regular maintenance is essential for preserving the performance and extending the service life of this bearing. Due to its open design, careful monitoring of operating conditions and regular lubrication are indispensable. A continuous lubrication groove and three lubrication holes facilitate relubrication, particularly in dusty or humid environments. The choice of lubricant is critical, especially at high temperatures. With the use of a suitable lubricant, operation at temperatures up to 200 °C is possible. For optimal stability, an interference fit on the shaft is recommended.

Sealing:
The bearing is not equipped with integrated seals. The open design facilitates inspection and maintenance but makes the bearing more susceptible to contamination. Dust, solid particles and moisture can impair performance if not properly controlled. However, the continuous groove and the three lubrication holes in the outer ring help discharge contaminant particles.

Brand information:
SKF was founded in Sweden in 1907 and is one of the world’s leading manufacturers of rolling bearings, lubrication systems and maintenance solutions. Active in over 130 countries, the brand stands for innovation, reliability and sustainable performance. SKF supplies numerous industrial sectors worldwide.

Strengths:
• Carries high radial and axial loads simultaneously in both directions
• Compensates misalignment and shaft deflection without loss of performance
• Lightweight pressed-steel cages (ideal for high speeds)
• Open design for easy inspection and maintenance
• Integrated lubrication system with continuous groove and three lubrication holes
• Suitable for operating temperatures up to 200 °C when using a suitable lubricant

Applications:
This self-aligning bearing is used in numerous industrial sectors where high loads and variable speeds are required. It is particularly suitable for conveyor systems, crushers, industrial fans, heavy-duty pumps, steel industry plants and agricultural machinery. Thanks to its design, it is ideal for fixed-bearing applications and environments where perfect shaft alignment cannot be guaranteed. Even under high thermal and dynamic loads it provides a reliable solution.
