Detailed Technical Data Sheet: SKF Explorer 21310 E/C3 Bearing

1. Product Description

The SKF Explorer 21310 E/C3 bearing is a radial spherical roller bearing designed for superior performance in high-speed, high-load industrial applications. The SKF Explorer line represents the pinnacle of SKF technology, offering significant improvements compared to standard bearings in terms of durability and reliability.

2. Construction and Materials

• Roller Material: High quality chrome steel, known for its wear resistance and durability.
• Ring Material (Internal and External): Chrome steel, designed to ensure long life and high resistance.
• Cage: Polymer or steel cage, depending on specification. The cage is designed to reduce friction and keep the rollers in place.
• Lubrication: Pre-lubricated with high performance grease to ensure long life and reduce friction.

3. Measurements and Technical Specifications

• Internal Diameter (d): 50 mm
• External Diameter (D): 110 mm
• Width (B): 27mm
• Weight: About 0.85 kg
• Bearing Type: Radial spherical roller bearing, designed to support high radial and axial loads.
• Precision Tolerance: Normal, with standard tolerances for general applications.

4. Mechanical Characteristics

• Radial Load Capacity: High radial load capacity, suitable for supporting heavy loads and difficult working conditions.
• Axial Load Capacity: Moderate, capable of supporting axial loads in both directions.
• Tolerance and Accuracy: The Explorer Series offers significant improvements in life over standard bearings, thanks to advanced design and high-quality materials.
• Preload: Not specified for the E/C3 version, which generally indicates a higher clearance tolerance than other versions.

5. Mathematical Formulas for Characteristics

• Dynamic Load Capacity (C): The formula for calculating the nominal bearing life is:

  $$L$$

  Where:

  • L10L_{10} $L$ 10 ​=
  • CC $C$ = dynamic load capacity
  • FF $F$ = applied load

  The specific values ​​for the 21310 E/C3 bearing should be consulted in the SKF catalog to determine the bearing life based on the applied load.

6. Sectors of Use

• Manufacturing Industry: Used in machines and equipment that require high resistance to loads and demanding working conditions.
• Mining and Cement Industry: Suitable for applications requiring robust and durable bearings in harsh environments.
• Energy and Wind: Used in wind turbines and other energy equipment that operate at high speeds and in harsh conditions.
• Automotive: Used in components such as crankshafts and differentials.

7. Advantages of Purchasing Ready to Ship in Stock

• Immediate Availability: Reduces machine downtime and increases operational efficiency.
• Reduced Costs: In-stock purchases are often cheaper than special orders.
• Guaranteed Quality: SKF Explorer offers high quality and reliability, ensuring superior performance compared to standard bearings.
• Lower Risk of Obsolescence: Stock availability reduces the risk of delays due to supply problems and ensures operational continuity.
