6308N/C3 Bearing Product Overview & Core Advantages
The 6308 C3 is a metric single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This open-type bearing delivers exceptional radial load capacity and is characterized by its snap ring groove on the outer ring, which facilitates secure axial location and simplifies housing design. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and consistent performance. Its optimized C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, providing operational stability across a wide temperature range.
6308N/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 63: Indicates the bearing series, defining the dimensional boundary and performance characteristics.
- 08: Specifies the bore diameter; 08 × 5 = 40 mm.
- C3: Denotes a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where operational temperatures fluctuate significantly.
6308N/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove construction with precision-ground chrome steel rings and balls provides a high radial dynamic load rating of 915 lbf and a static load rating of 5395 lbf, ensuring durability under significant stress.
- Simplified Assembly & Axial Location: The integrated snap ring groove on the outer ring allows for secure mounting within a housing, reducing the need for complex end caps and minimizing assembly time.
- Operational Versatility: The C3 clearance accommodates dimensional changes from interference fits and thermal expansion, preventing premature failure due to excessive preload. This contributes to a high limiting speed of 7,500 rpm.
- Broad Compatibility: As an open bearing without lubrication, it offers flexibility for systems with centralized lubrication or allows for the application of specialized greases or oils tailored to specific operational environments.
