308/C3 Bearing Product Overview & Core Advantages
The 308/C3 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Engineered to primarily accommodate radial loads, this open-type bearing offers high reliability and versatility. Its key advantages include a generous C3 radial internal clearance, which accommodates thermal expansion in demanding operating conditions, and a high limiting speed of 8,500 rpm. Manufactured from durable chrome steel and built to ABEC 1 | ISO P0 tolerance standards, the 308/C3 provides a cost-effective solution for applications requiring dependable performance under significant loads.
308/C3 Bearing Model Code Explained, Specifications & Naming Convention
| 308 | Standard bore diameter code indicating a 40mm bore and 90mm OD. |
| /C3 | Denotes a greater than normal radial internal clearance. This is critical for applications with high thermal gradients or where interference fits are used, preventing premature failure due to excessive preload. |
308/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and chrome steel construction enable high radial dynamic (10,274 lbf) and static (8,093 lbf) load ratings.
- Optimized for Thermal Expansion: The C3 clearance is a defining feature, ensuring stable operation and preventing seizure in applications where bearing temperatures rise significantly.
- High-Speed Capability: With a limiting speed of 8,500 rpm, this bearing is suitable for a variety of high-velocity applications.
- Versatile & Cost-Effective: The open design allows for custom lubrication schemes, while the standard ABEC 1 precision offers an excellent balance of performance and value.
