Key Design Features & Advantages
- Double-Row Spherical Roller Configuration: Features two rows of symmetrically arranged barrel-shaped rollers that distribute loads evenly across raceways, maximizing load-carrying capacity and operational stability.
- Self-Alignment Capability: The spherical outer raceway allows the bearing to compensate for misalignment of up to 2° and shaft deflection, eliminating additional stress on the bearing and adjacent components.
- Relubrication-Friendly Design (Suffix E): Equipped with an outer ring featuring circumferential lubrication grooves and three lubrication holes, enabling efficient lubrication (supplementary lubrication) throughout the bearing's service life - critical for high-temperature or high-contamination applications
- Robust Steel Cage: Utilizes a pressed steel cage that provides excellent rigidity, wear resistance, and thermal stability, ensuring consistent roller guidance even under extreme load conditions.
- Optimized Internal Geometry: SKF's proprietary design minimizes stress concentration at contact points, reduces friction, and enhances fatigue life, outperforming standard spherical roller bearings in comparable applications.
