SKF bearings are developed for customer satisfaction. The best confirmation of the total quality of SKF spherical roller bearings is their success on the market. There are twice as many SKF spherical roller bearings in service as those of any other bearing manufacturer. This is not just by chance, SKF spherical roller bearings are well-proven in the field and undergo continuous development to provide improved performance.The latest examples include the introduction of SKF Explorer bearings, which opened up new application horizons, and sealed bearings.

1. Does the 22220 EK have lubrication/relubrication features?

Yes. It typically includes a lubrication groove plus three lubrication holes in the outer ring.

2. What are it's limitations?

4,500 rpm is the maximum rpm. For higher speeds one may need a bearing with different internal design or lower friction/hybrid/special steel. Using this limits the risk of overheating or reduced life.

3. What are typical applications for the SKF 22220 EK?

Heavy machinery like gearboxes, crushers, vibrating screens and fans (where large radial loads and possible shaft/housing misalignment occur).
