SKF 22322 EJA/VA406 SPHERICAL ROLLER BEARING

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 belongs to the category of self-aligning bearings with high load-carrying capacity and is distinguished by its ability to withstand high levels of vibration. This type of bearing is designed to withstand heavy loads while accommodating misalignment and shaft deflection. It features two rows of rollers, a C4 radial clearance, a hardened sheet steel cage with an E-type design, a PTFE-coated cylindrical bore, as well as an annular groove and lubrication holes in the outer ring.

Features:

This double-row roller bearing is designed to provide excellent load stability in environments subject to high levels of vibration (VA406). This model features a reinforced structure capable of operating effectively under heavy loads, at high speeds, with high accelerations, and under considerable centrifugal forces. It is also equipped with a PTFE-coated cylindrical bore, designed to facilitate installation and improve dynamic performance in the presence of vibrations. Its surface-hardened sheet steel cage enhances wear resistance. Combined with the E-type design and its two deep-drawn steel cages, it ensures uniform load distribution and minimizes inertia, promoting stable operation even at high speeds. Its C4 internal radial clearance accommodates thermal expansion without interfering with operation, thereby limiting heat buildup. The bearing features an annular groove and three lubrication holes in the outer ring for effective relubrication.

Maintenance:
Since this bearing is not pre-lubricated, proper lubrication must be ensured upon installation. The annular groove and lubrication holes facilitate relubrication during operation, thereby extending the component’s service life. Regular inspection is recommended to check for contamination or signs of wear. If impurities are detected, thorough cleaning of the housing is essential before relubrication.

Sealing:
This bearing is designed without seals. It is therefore susceptible to contamination by solid particles, dust, or moisture. This design requires strict control of the cleanliness of the installation areas and operating conditions. However, its open design facilitates visual inspections and maintenance work.
