6308 TC/C78 Bearing Product Overview & Core Advantages

The 6308 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Engineered to primarily accommodate radial loads, it also has the capacity to handle moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision and consistent operation. Its open design allows for versatile lubrication options, making it a fundamental and highly versatile component for machinery requiring robust and dependable rotational support.

6308 TC/C78 Bearing Model Code Explained, Specifications & Naming Convention

The model number 6308 follows a standard industry designation. Here is a breakdown of its key characteristics:
  • 63: Indicates the bearing series, defining the cross-sectional dimensions and load capacity profile.
  • 08: Specifies the bore diameter. For metric bearings, this is calculated as 08 * 5 mm = 40 mm.
  • No Suffix: The absence of additional suffixes signifies the following standard features:
    • Open seal type (no shields or seals).
    • Standard CN radial internal clearance.
    • Standard cage and material configuration.
    • No pre-lubrication (None).

6308 TC/C78 Bearing Structural Features & Performance Benefits

The performance of the 6308 bearing is a direct result of its fundamental deep groove ball bearing construction. The uninterrupted deep raceways on both rings provide optimal contact with the balls, ensuring smooth rotation and high radial load capacity. The use of high-grade chrome steel for all components (rings, balls, and cage) guarantees high strength, durability, and resistance to wear. The open structure facilitates easy re-lubrication in service, which is critical for extending bearing life in demanding applications. With a limiting speed of 7,500 rpm, it is well-suited for a broad spectrum of operational speeds.

6308 TC/C78 Bearing Typical Application Areas

This versatile bearing is a common choice across numerous industries due to its balanced performance characteristics. Typical applications include:
  • Electric Motors and Generators
  • Gearboxes and Power Transmission Systems
  • Industrial Pumps and Compressors
  • Material Handling Equipment (e.g., conveyor pulleys)
  • Agricultural Machinery
  • General Industrial Machinery requiring reliable radial support.
