Advantages of purchasing ready for delivery from stock:

1. Immediacy of delivery: Guarantees immediate availability of the product, reducing downtime of machines and processes.
2. Reduced cost: Buying in stock can offer economic advantages compared to a customized order, especially for large quantities.
3. Quality control: SKF bearings are produced to high quality standards, ensuring reliable and consistent performance. Having products already available avoids production delays or non-compliance.

Description of the manufacturer (SKF):

SKF, founded in 1907, is a world leader in the production of bearings, sealing solutions and lubrication systems. Based in Sweden, the company stands out for the innovation and quality of its products. Their range of high precision bearings are used in numerous industrial and technological sectors, ensuring superior performance thanks to continuous research and development.

Related mathematical formulas:

• Dynamic load capacity: The formula for determining the nominal bearing life (L10) is:

  $$L$$

  Where C is the dynamic load, P is the applied load, and p is an exponent based on the bearing type (for ball bearings, p = 3).

• Limiting speed: Limiting speed is directly related to lubrication and heat dissipation. For high speeds, the use of lubricating oil is preferable.

These characteristics make the SKF 7216 CDGB/P4A bearing a component of excellence in the industrial and technical fields​
