SKF SPHER ROLLER BEARING 22315 EKJA/VA405

Spherical roller bearings play a key role in the proper operation of equipment subjected to high mechanical loads. Their robust design ensures reliable and continuous performance, even under unstable or demanding operating conditions.

This SKF spherical roller bearing stands out for its ability to withstand heavy loads while maintaining excellent operational stability. Thanks to its self-aligning design, it effectively compensates for misalignment, shaft deflection, and mechanical distortions. Robust, reliable, and built to last, it is the ideal solution for optimizing machine service life and maintaining maximum productivity.

Features:
This bearing features two symmetrical rows of rollers, mounted in a surface-hardened steel cage. This configuration ensures uniform distribution of radial and axial loads in both directions. Its 1:12 tapered bore allows for a tight fit and precise alignment, reducing vibrations and improving service life (ovalization, fretting, etc.). It is recommended when the load rotates relative to the shaft. The E design, featuring two stamped window cages and a shoulderless inner ring, ensures excellent rotational stability, even at high speeds. The C4 internal radial clearance, which is greater than the standard, helps absorb thermal expansion and limits overheating. Together, these features contribute to reduced inertia, making this bearing ideally suited for high-speed applications.

Maintenance:
This bearing requires regular lubrication to ensure proper operation. It features an annular groove and three lubrication holes on the outer ring, facilitating the introduction of lubricant and the removal of contaminants. It is recommended to use a high-performance grease compatible with high temperatures and heavy loads. During maintenance, visual inspection is easy thanks to its open design. It is essential to thoroughly clean the housing and components before relubrication, especially if dust or abrasive particles are present.

Sealing:
This bearing is designed without seals. The absence of integrated sealing components reduces internal friction, enabling smoother, more energy-efficient operation and higher speeds. However, this open design results in increased sensitivity to contaminants such as dust, moisture, and solid particles.

Brand Information:
SKF is a global leader in bearing technology, founded in 1907 in Sweden. With a presence in more than 130 countries, the group offers innovative solutions for industrial reliability. Its mission is to reduce energy consumption and maintenance costs through high-precision, durable products. SKF invests heavily in R&D every year to remain at the forefront of mechanical performance.

Key Benefits:
- Compensates for misalignment and shaft deflection.
- Withstands very high radial and axial loads.
- Open design facilitates maintenance, inspection, and energy efficiency.
- Hardened steel cage resistant to wear and heavy loads.
- Suitable for high rotational speeds thanks to C4 internal clearance.
- Tapered mounting ensures a precise and tight fit.

Applications:
Designed for industrial environments subject to intense stress, this bearing is ideal for vibrating equipment such as screens, saw frames, and road rollers. Its exceptional mechanical strength allows it to withstand dynamic loads, sudden accelerations, and high-speed stresses over the long term. Thanks to its increased internal clearance (C4), it effectively absorbs thermal expansion and ensures consistent stability.
