SKF HRA+ SPHR ROLLER BRG 22332 CCJA/W33VA405

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 is a mechanical component designed for vibrating applications, capable of withstanding significantly higher accelerations than corresponding standard bearings. Thanks to its symmetrical double-row roller design, it ensures uniform load distribution while accommodating misalignment. This model also features two windowed cages made of stamped sheet steel, a shoulderless inner ring, and a floating guide ring centered on the inner ring. It also has an annular groove and three lubrication holes, thereby optimizing maintenance and lubricant distribution.

Features:
This self-aligning bearing for vibrating applications is particularly robust and withstands very high loads, speeds, accelerations, and centrifugal forces. It is equipped with a cylindrical bore that facilitates direct mounting on the shaft. Its CC internal design, with its two windowed cages made of stamped sheet steel and its shoulderless inner ring, promotes precise roller guidance and good load distribution. Its above-standard C4 internal radial clearance, along with its open design, reduces internal friction. This facilitates high-speed operation while limiting heat build-up and allowing for better adaptation to thermal expansion.

Maintenance:
This double-row roller bearing requires regular relubrication to maintain its performance. To this end, it is equipped with an annular groove and three lubrication holes on the outer ring to facilitate the application of lubricant. The frequency of this maintenance depends heavily on operating conditions, particularly speed, temperature, and the level of exposure to contaminants. Regular application of a suitable lubricant not only reduces friction and wear but also helps flush out any impurities. Operating temperatures can reach 200°C at the rings, but the choice of lubricant is critical for operation under these extreme conditions.

Sealing:
This model is an open-type bearing with no built-in seals. This design offers low rolling resistance and allows for quick visual inspection, but makes it more vulnerable to contaminants. To minimize risks associated with dust or moisture, it is essential to maintain clean conditions around the bearing.

Brand Information:
SKF (Svenska Kullager-Fabriken) is a Swedish multinational group founded in 1907 and a world leader in the field of mechanical bearings. SKF is one of the world’s leading suppliers of bearings, seals, mechatronic components, lubrication systems, and services designed to improve the reliability of rotating equipment and ensure its performance. SKF products can be used anywhere there is motion.

Key Benefits:
- Suitable for bearings in vibrating applications
- Withstands high radial and axial loads in both directions;
- Self-aligning capability, ideal for misalignment or shaft deflection;
- C4 radial clearance for better thermal tolerance and reduced heat build-up;
- Hardened sheet steel cages offering good wear resistance;
- High-speed operation facilitated by the absence of seals and the open design.

Applications:
This bearing is designed to withstand the severe mechanical stresses of vibrating applications, such as road rollers, saw frames, or vibrating screens. This type of bearing is also commonly used in elevators, machinery in the textile and food industries, and cranes. It is also found in heavy industrial equipment such as crushers, conveyors, or gearboxes, where its robustness and stability make it a preferred choice. Thanks to its versatility, it is widely used in sectors such as cement manufacturing, metallurgy, paper production, and mining.
