1207-K C/3 Bearing Product Overview & Core Advantages
The 1207-K C/3 is a metric double row angular contact ball bearing engineered for applications requiring high precision and robust performance. Featuring a tapered bore (1:12) and open construction, this bearing is designed to handle significant radial loads efficiently. Its double row design provides enhanced rigidity and stability, making it suitable for demanding industrial environments. The bearing comes pre-lubricated and features a CN radial internal clearance, optimized for general operating conditions and ensuring reliable performance across a temperature range of -30°C to 110°C.
1207-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Standard bore diameter (35 mm) and dimension series |
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise mounting and dismounting on tapered shafts |
| C/3 | Specifies the radial internal clearance group (CN - Normal clearance) and lubrication status |
1207-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing configuration provides superior radial stiffness and can accommodate substantial radial loads (dynamic: 4275 lbf, static: 1350 lbf), ensuring stable operation under varying load conditions.
- Precision Tapered Bore: The 1:12 tapered bore allows for accurate axial positioning and secure fitting on adapter sleeves or tapered shafts, enhancing overall system precision.
- Optimized Cage Design: The nylon cage contributes to smooth operation, reduced friction, and suitability for high-speed applications (limiting speed: 13,000 rpm).
- Material & Durability: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and longevity, compliant with ROHS and REACH standards.
- Pre-lubricated & Maintenance-Friendly: Factory-applied lubrication and open design facilitate initial operation and allow for re-lubrication in service, supporting extended bearing life.
1207-K C/3 Bearing Typical Application Areas
- Electric Motors & Generators: Ideal for supporting rotors in motors requiring high-speed and radial load capacity.
- Industrial Gearboxes: Used in gearbox assemblies where precise shaft alignment and radial load handling are critical.
- Material Handling Equipment: Suitable for conveyor pulleys, rollers, and other machinery subjected to consistent radial forces.
- Agricultural Machinery: Employed in implements such as balers and harvesters that demand robust and reliable bearing performance.
- General Industrial Machinery: Applicable in pumps, fans, and other rotating equipment where double row angular contact ball bearings enhance operational stability.
