1207 C3 Bearing Product Overview & Core Advantages
The 1207 C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Its compact bearing dimensions (35mm bore, 72mm OD, 17mm width) facilitate space-saving designs. Engineered with a nylon cage and C3 radial internal clearance, this precision bearing is optimized for stable operation across a wide temperature range and is pre-lubricated for immediate use, ensuring long service life and reduced maintenance needs.
1207 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 1207 | Standard bearing series designation, indicating a 35mm bore and 72mm outside diameter. | Defines the core bearing dimensions for interchangeability and selection. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Allows for thermal expansion in applications, preventing seizure and ensuring reliable operation in heated environments or with interference fits. |
1207 C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior radial and moment load support compared to single row bearings, making it ideal for applications with significant combined loads.
- Optimized for Performance: The lightweight nylon cage ensures smooth operation at the limiting speed of 13,000 rpm, reducing friction, heat generation, and wear.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, this bearing offers high fatigue life and durability under dynamic loads (radial dynamic load rating: 4275 lbf).
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, simplifying installation and providing immediate protection, which is suitable for the specified temperature range of -30°C to 110°C.
1207 C3 Bearing Typical Application Areas
This double row angular contact ball bearing is well-suited for a variety of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring robust support for combined loads
