SKF 7216 CDGB/P4A Bearing – Super Precision Angular Ball Bearing PRICE 390 EURO

1. General Description
The SKF 7216 CDGB/P4A bearing is a high-precision angular contact ball bearing, designed for applications requiring high rotational speeds, such as in machine tools and precision equipment. Part of SKF's P4A series, this model is optimized for smooth operation, greater rigidity and axial load capacity in one direction.

2. Technical Characteristics

• Materials : High quality steel rings and ceramic balls (optional), ideal for reducing weight and increasing rigidity at high speeds. The option of ceramic balls reduces friction and centrifugal forces.
• Dimensions:
  • Internal diameter: 80mm
  • External diameter: 140mm
  • Width: 26mm
• Weight : Approximately 1.35 kg.
• Contact Angle : 15°, ideal for combinations of radial and axial loads.
• Lubrication : Grease or oil, with the possibility of requesting variants with lubrication holes for direct cooling.

3. Mechanical Performance and Advantages

• Accuracy : The P4A precision class guarantees high accuracy in applications, reducing vibrations and increasing operational stability.
• Load Capacity : Large internal balls increase load capacity compared to other bearings of the same size.
• Operating Speed : Designed to maintain high speeds, especially with the use of ceramic balls, which reduce the heat generated during operation.

4. Formulas and Applications
Dynamic (C) and static (C0) load capacity can be calculated using standard SKF formulas to evaluate bearing life under operating conditions. The L10 formula for nominal bearing life is commonly used to estimate operating life based on specific load and speed.

5. Application Sectors
These bearings are ideal for use in machine tools, precision equipment, industrial machinery and in sectors where high speeds and low noise are required. They are particularly appreciated in assemblies in the axes of CNC machines, grinding machines and high-speed milling machines.

6. Advantages of Purchasing in Stock
Purchasing high precision bearings, such as the 7216 CDGB/P4A model, ready for delivery allows companies to reduce machine downtime and guarantee a rapid supply in case of sudden replacements, thus ensuring continuity essential operational.

7. Assembly
The assembly of the SKF 7216 CDGB/P4A bearing requires care to avoid unbalanced stresses on the internal components. SKF recommends the use of specific mounting tools and compliance with tolerances to prevent damage to contact surfaces.

8. Manufacturer
