General Technical Characteristics of SKF and FAG Bearings

1. Material : SKF and FAG bearings are made of high quality steel, designed to ensure wear resistance, hardness and long life. The material is corrosion resistant and allows optimal operation even in harsh conditions.

2. Bearing type : Available models include various types of bearings, such as deep groove ball bearings, roller bearings, double radius bearings and radial contact bearings, depending on the specific needs of the application.

3. Dimensions:

   • SKF and FAG bearings have various internal and external diameters, ranging from 30 mm to 200 mm (or even larger in some variants).
   • Pad widths vary depending on the model, but generally range from 10mm to 50mm .
   • maximum rpm values ​​(rotation speed) and operating pressures to ensure safe and optimal operation.

4. Type of sealing:

   • Many models are equipped with rubber seals (such as the 2RS1 models), which prevent dust and moisture from entering, increasing bearing life in harsh working environments.
   • open system versions for applications requiring external lubrication.

5. Load capacity:

   • SKF and FAG bearings are designed to support radial and axial loads. The load capacity depends on the type of bearing and its specific application.
   • Bearings with C3 are ideal for high vibration environments and higher temperature operations.

6. Weight:

   • The weight of a bearing can vary from 500 g to 10 kg depending on the size and type of bearing.

Use in Industrial Sectors

SKF and FAG bearings are used in a wide range of industrial sectors, thanks to their robustness and versatility:

• Automotive : for applications such as engines, transmissions, and suspension systems.
• Heavy industry : bearings for heavy machinery, lifts, and construction equipment.
• Agricultural sector : for agricultural machines, tractors and implements.
• Marine and railway sector : used in naval engines, turbines and railway traction systems.
• Energy sector : in generators and turbines.
• Machine maintenance and manufacturing industry : for precision bearings and lifting equipment.

Assembly and Maintenance

Mounting SKF and FAG bearings is relatively simple, but requires attention to cleanliness and proper lubrication. Here are the main steps:

1. Preparation of the mounting site : The surface where the bearing will be mounted must be clean and free of dust and debris.
2. Lubrication : Bearings must be lubricated properly to reduce friction. SKF and FAG offer both pre-lubricated bearings and versions that require external lubrication.
3. Alignment : It is essential that the bearing is aligned correctly to avoid wear problems and to ensure maximum life.
4. Bearing assembly : Use appropriate tools such as extractors for assembly, avoiding damage to the bearing during installation.

Maintenance includes periodic inspections for signs of wear, abnormal noises or vibrations. It is recommended to replace the bearings when signs of damage are observed.

How to Correctly Size a Bearing

The correct sizing of a bearing depends on various factors:

1. Radial load : Determine the force that the bearing must withstand in a direction perpendicular to the axis of rotation.
2. Axial load : Determine the force acting along the bearing axis.
3. Rotational speed : Determine the number of revolutions per minute (rpm) and select a bearing that supports that speed.
4. Environmental conditions : Consider temperature, humidity and presence of corrosive substances or dust in the working environment.

Once this data has been collected, it is possible to choose the type of bearing that offers the best combination of load resistance and rotation speed .

Useful formulas:

• Equivalent load: $P$ Where:
  • FrF_r $F$ r ​is
  • FaF_a $F$ a ​is
  • CrC_r $C$ r ​and CaC_a $C$ a ​are
