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
- 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.
