SKF 23028-2CS5/VT143 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 bearing combines performance, durability, and reliability. Thanks to its self-aligning technology and double row of rollers, it can handle heavy loads while compensating for misalignment. Ideal for applications where stability and resistance to extreme conditions are essential.

Features:
This self-aligning roller bearing stands out for its ability to automatically compensate for misalignment. Thanks to its deep-drawn steel sheet cages, loads are distributed evenly throughout the bearing. The cylindrical bore allows for direct mounting on the shaft, simplifying installation without requiring additional components. Its design, featuring integrated seals and factory lubrication, ensures immediate operation. Thanks to its robust construction, this spherical roller bearing is suitable for moderate speeds while maintaining excellent stability. 

Maintenance:
This bearing is pre-lubricated with high-performance grease (LGEP 2), ensuring optimal protection from the moment of installation. When relubrication is necessary, inject the grease through the three lubrication holes in the outer ring, preferably while the bearing is rotating to ensure even distribution. It is important never to wash this product before use. To maintain the bearing’s performance, perform regular checks of the lubrication level and inspect the condition of the seals. Avoid contamination during maintenance by thoroughly cleaning the lubrication area before service. The ideal operating temperatures range from -20 °C to +110 °C, with a wider tolerance for mechanical components, allowing for extended use under a variety of conditions.

Sealing:
Equipped with HNBR sliding seals on both sides, this self-aligning ball bearing is very well protected against moisture, dust, and other contaminants. HNBR is a high-performance elastomer that resists high temperatures, industrial oils, and harsh environments. These seals, reinforced with a steel cage, maintain sealing performance while limiting the ingress of solid particles. This protective barrier significantly extends the product’s service life, even in applications exposed to severe conditions. However, this design slightly reduces the maximum permissible speed and efficiency, in exchange for reduced maintenance requirements.
