209/C3 Bearing Product Overview & Core Advantages
The 209/C3 is a metric single row deep groove ball bearing engineered for reliable performance in general industrial applications. Characterized by its open design and standard C3 radial internal clearance, this bearing is optimized to handle significant radial loads while accommodating moderate axial loads in both directions. Its ABEC 1 (ISO P0) tolerance class ensures consistent quality and dependable operation, making it a versatile and cost-effective solution for a wide range of machinery and equipment.
209/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 209 | Basic Bearing Number | Defines the standard dimensions: 45mm bore, 85mm OD, 19mm width. |
| /C3 | Radial Internal Clearance | Indicates a greater-than-normal radial internal clearance. This is crucial for applications involving thermal expansion, such as in electric motors, or where fits result in a reduction of clearance. |
209/C3 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 7913 lbf and a static load rating of 6744 lbf, ensuring durability under demanding conditions.
- Optimized for Thermal Applications: The specified C3 clearance is a key performance feature, allowing the bearing to maintain optimal operation by compensating for dimensional changes caused by heat generation or tight interference fits, thereby preventing seizure and premature failure.
- High-Speed Capability: With a limiting speed of 8,500 rpm, it is suitable for a variety of high-speed applications. The pressed steel cage provides secure ball guidance and contributes to smooth operation at high rotational velocities.
- Application Flexibility: The open design allows for versatile lubrication options based on specific operational needs, while the wide operating temperature range (-30°C to 120°C) ensures performance across diverse environments.
209/C3 Bearing Typical Application Areas
The 209/C3 bearing is a fundamental component found in numerous industrial sectors. Its reliability and specific clearance make it ideal for:
- Electric Motors and Generators (a primary application for C3 clearance bearings)
- Industrial Gearboxes and Transmissions
- Agricultural Machinery
- Material Handling Conveyors
- Pumps and Fans
- General machinery requiring a robust, standard-duty ball bearing.
