Łożyska baryłkowe SKF 22211 EK/W64

Łożyska baryłkowe mają dwa rzędy symetrycznych wałeczków, wspólną kulistą bieżnię pierścienia zewnętrznego i dwie bieżnie pierścienia wewnętrznego nachylone pod kątem do osi łożyska. Punkt środkowy kuli w bieżni pierścienia zewnętrznego znajduje się na osi łożyska.

This self-aligning roller bearing features two rows of rollers, giving it excellent self-aligning capability in the event of shaft deflection. It withstands heavy radial and axial loads in both directions. This model features a robust design and advanced lubrication technology, ensuring optimal durability and reliability.

Features:
This bearing incorporates two rows of rollers, giving it excellent load-carrying capacity. It is equipped with a stamped steel cage, which reduces inertia for better performance at high speeds. Its 1:12 tapered bore facilitates quick mounting on a shaft with or without a sleeve, reducing vibrations and ensuring a secure fit. Its open design, combined with an optimized E-structure, makes it particularly effective for heavy-duty applications where reliability and performance are essential.

Maintenance:
This self-aligning roller bearing is lubricated for life using Solid Oil technology, a polymer material saturated with oil. This solution ensures permanent lubrication and forms a barrier against contaminants. No relubrication is necessary, but it is recommended to maintain a clean environment during installation and operation to prevent the ingress of abrasive particles. Periodic inspection of the bearing’s performance (noise, vibration, temperature) helps anticipate potential deterioration and ensures reliable long-term operation. The permissible operating temperature is limited by the properties of the integrated polymer lubricant, with a minimum start-up temperature of -50 °C and a maximum continuous temperature of 85 °C.

Sealing:
This self-aligning roller bearing features an open design with no seals. This characteristic reduces rolling resistance, thereby optimizing efficiency and enabling high rotational speeds without excessive overheating. Solid Oil technology provides protection against contaminants by filling the entire free space, repelling liquids and dust. This solution is ideal for applications exposed to harsh conditions, as it withstands humid environments and frequent cleaning, even at high pressure.
