629/C3 Bearing Product Overview & Core Advantages
The 629/C3 is a single row deep groove ball bearing designed for high performance in general industrial applications. As a metric bearing, it excels in handling radial loads efficiently. Its key advantages include a C3 radial internal clearance, which provides greater operational tolerance for applications involving thermal expansion or heavy loads. Manufactured from high-grade chrome steel for all its core components, it offers excellent durability and a long service life, making it a reliable and cost-effective solution for a wide range of machinery.
629/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | The basic bearing designation, indicating a single row deep groove ball bearing with a 9 mm bore, 26 mm OD, and 8 mm width. |
| /C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with potential shaft misalignment, high speeds, or where operational heat generation is a factor. |
629/C3 Bearing Structural Features & Performance Benefits
- Robust Construction: Built entirely from chrome steel (rings, balls, and cage), this bearing ensures high strength, wear resistance, and consistent performance under load.
- Optimized Internal Clearance: The C3 clearance is a defining feature, allowing the bearing to accommodate thermal expansion and prevent seizure in demanding conditions, thereby enhancing operational reliability.
- High-Speed Capability: With a limiting speed of 28,000 rpm, it is suitable for applications requiring rapid rotation. The open design and precision ABEC 1 | ISO P0 tolerance contribute to smooth, low-vibration operation at high velocities.
- Versatile Load Handling: Its deep groove raceway geometry is optimized for radial dynamic load rating of 873 lbf and a static load rating of 357 lbf, making it capable of handling significant radial forces.
- Application Flexibility: The open seal type allows for custom lubrication strategies, while the wide operating temperature range (-30°C to 120°C) ensures performance in various environments.
629/C3 Bearing Typical Application Areas
This bearing is widely used in industries and equipment requiring reliable rotational support, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
