SKF 6308 2Z C3: Understanding the Nomenclature and Specifications

Understanding the SKF 6308 Designation

What Is SKF 6308?

SKF 6308 is a specific type of ball bearing produced by SKF, a leading manufacturer in the bearing industry. This designation provides key information about the bearing’s characteristics. The number 6308 indicates that it belongs to the 6300 series of deep groove ball bearings. In this series, 63 denotes a single row deep groove ball bearing. The 08 at the end signifies the bore size, which is 40mm for this particular bearing.

Deep groove ball bearings are versatile and widely used in various applications. They can handle both radial and axial loads in both directions. This makes them suitable for high-speed operations and applications that require low friction and smooth rotation. The SKF 6308 is known for its robustness and reliability in diverse industrial settings.

Deciphering the 2Z C3: A Closer Look at the Bearings

The additional designations ‘2Z’ and ‘C3’ in SKF 6308 2Z C3 provide more specific details about this bearing:

• 2Z: This indicates that the bearing has steel shields on both sides. These shields help protect the bearing from contaminants and retain lubricant. This feature is particularly useful in environments where dust or debris might be present.
• C3: This denotes the internal clearance class of the bearing. C3 indicates a clearance that is greater than normal. This increased clearance can be beneficial in applications where the bearing might be subjected to higher temperatures or misalignment.

These additional features make the SKF 6308 2Z C3 suitable for a wide range of operating conditions. The combination of shielding and increased clearance enhances the bearing’s performance and longevity in challenging environments.

Key Specifications and Applications of SKF 6308 2Z C3

Material and Manufacturing

The SKF 6308 2Z C3 is manufactured using high-quality materials and advanced production techniques. The rings and rolling elements are typically made from chrome steel, known for its durability and resistance to wear. This material choice ensures long service life and reliable performance under various loads and speeds.

The manufacturing process involves precision grinding and honing of the raceways. This results in smooth surfaces that minimize friction and noise during operation. The balls are also carefully selected and matched to ensure uniform load distribution and optimal rolling contact.

The shields (denoted by 2Z) are usually made from pressed steel. They are designed to fit snugly against the inner ring, providing effective protection against contaminants while allowing for smooth rotation.

Dimensions and Tolerances

The SKF 6308 2Z C3 has specific dimensions that are crucial for proper fitting and function:

• Bore diameter: 40 mm
• Outer diameter: 90 mm
• Width: 23 mm

These dimensions are manufactured to tight tolerances to ensure consistency and interchangeability. The C3 clearance class means that the internal radial clearance is slightly larger than standard. This can range from 0.028 mm to 0.046 mm, depending on the specific application requirements.

Proper understanding of these dimensions and tolerances is essential for correct installation and optimal performance in various machinery and equipment.
