SKF HRA+ SPHR ROLLER BRG 22320 EJA/VA405

Self-aligning roller bearings play a key role in the proper functioning 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 designed to withstand heavy radial and axial loads in both directions while compensating for misalignment. Its mechanical robustness and ability to maintain stable performance under severe operating conditions set it apart in the industrial bearing market.

Features:
This spherical roller bearing features two symmetrical rows of rollers that ensure uniform load distribution. Its three-piece carbonitrided cage, with a guide ring centered on the outer ring, offers excellent resistance to wear and mechanical deformation. Thanks to its cylindrical bore, it can be easily mounted on machined shafts without requiring any special accessories. The optimized Type E design, with its redesigned raceways and larger-diameter rollers, improves rotational stability and reduces internal stresses. The standard internal radial clearance allows for optimal adaptation to thermal variations while ensuring smooth and consistent rotation, even under dynamic loads. This VA405 version is specifically designed to withstand intense vibrations with accelerations of up to 5 g.

Maintenance:
This bearing is shipped without initial lubrication, allowing you to select a lubrication method perfectly suited to the intended application. It is essential to provide for regular relubrication via the annular groove and the three lubrication holes integrated into the outer ring. For heavily contaminated environments, it is recommended to clean the housings beforehand before each lubrication operation. Periodic inspection of the clearance, temperature, and appearance of the rolling surfaces helps detect any signs of premature wear. In case of exposure to high temperatures, a specific high-temperature lubricant must be used.

Sealing:
This bearing is of the open type and does not have integrated seals. This configuration has the advantage of reducing internal resistance and allowing for higher rotational speeds. However, the lack of protection against contaminants requires additional precautions regarding cleanliness. It is essential to ensure a clean and dry installation environment to prevent the ingress of dust or moisture.
