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

1. Product Description

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

2. Construction and Materials

• Roller Material: High quality chromium steel, known for its wear resistance and durability.
• Ring Material (Inner and Outer): Chrome steel, designed to ensure long life and high strength.
• Cage: Polymer or steel cage, depending on specifications. The cage is designed to reduce friction and hold 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): 27 mm
• Weight: Approx. 0.85 kg
• Bearing Type: Spherical roller bearing, designed to support high radial and axial loads.
• Precision Tolerance: Normal, with standard tolerances for general applications.

4. Mechanical Features

• 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 Precision: The Explorer Series offers significant improvements in durability over standard bearings, thanks to advanced design and high-quality materials.
• Preload: Not specified for the E/C3 version, which generally indicates a greater play tolerance than other versions.

5. Mathematical Formulas for Characteristics

• Dynamic Load Capacity (C): The formula to calculate the nominal bearing life is:

  $$L$$

  Where:

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

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

6. Sectors of Use

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

7. Advantages of Buying Ready-to-Deliver from Stock

• Immediate Availability: Reduces downtime and increases operational efficiency.
• Reduced Costs: Stock purchases are often cheaper than special orders.
• Guaranteed Quality: SKF Explorer offers high quality and reliability, ensuring superior performance compared to standard bearings.
