SKF 7216 CDGB/P4A Bearing – Super Precision Angular Contact 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 the SKF P4A series, this model is optimized for smooth operation, increased rigidity, and single-direction axial load carrying capacity.

2. Technical Features

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

3. Mechanical Performance and Advantages

• Accuracy : The P4A accuracy class ensures high accuracy in applications, reducing vibration and increasing operational stability.
• Load Capacity : Large internal balls increase load capacity over 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 carrying capacities can be calculated using standard SKF formulas to estimate bearing life under operating conditions. The L10 formula for nominal bearing life is commonly used to estimate bearing life based on specific load and speed.

5. Application Areas
These bearings are ideal for use in machine tools, precision equipment, industrial machinery, and in sectors requiring high speeds and low noise. They are particularly popular in assembly in CNC machine axes, grinding machines, and high-speed milling machines.

6. Advantages of Stock Buying
Buying high-precision bearings, such as the 7216 CDGB/P4A model, in stock allows companies to reduce machine downtime and ensure rapid supply in the event of unexpected replacements, thus ensuring essential operational continuity.

7. Mounting
Assembling the SKF 7216 CDGB/P4A bearing requires care to avoid unbalanced stresses on internal components. SKF recommends using specific mounting tools and adhering to tolerances to prevent damage to the contact surfaces.
