1214KC3 Bearing Product Overview & Core Advantages
The 1214KC3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. Featuring a metric taper bore (1:12), this bearing excels at handling combined radial and axial loads simultaneously. Its double row design provides superior stiffness and stability, making it ideal for high-precision machinery and equipment where reliable performance under significant loads is critical. The bearing comes pre-lubricated and features a C3 radial internal clearance, optimized for operational conditions requiring slight expansion or where higher temperatures are present.
1214KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1214 | Standard bore diameter code (70 mm) and dimension series. |
| K | Indicates a metric taper bore with a 1:12 ratio. |
| C3 | Specifies a greater radial internal clearance than normal (C0), suitable for applications with thermal expansion or where interference fits are used. |
1214KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides exceptional stiffness, enabling it to withstand significant combined radial and axial loads without compromising performance.
- Optimized Cage Design: The nylon cage ensures smooth operation, reduces friction, and contributes to the bearing's ability to achieve a limiting speed of 7,000 rpm.
- Taper Bore Advantage: The 1:12 taper bore allows for precise axial positioning and secure mounting on tapered shafts, enhancing overall system stability.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication ensures immediate operation and reduces initial maintenance requirements.
- Material Integrity: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational lifespan within a temperature range of -30°C to 110°C.
