1217KJC3 Bearing Product Overview & Core Advantages
The 1217KJC3 is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and the capacity to handle combined loads. Its double row design provides superior radial and axial load support in a compact bearing size (85mm bore x 150mm OD x 28mm width). Featuring a C3 radial internal clearance and factory-applied lubrication, it is optimized for stable performance under varying thermal conditions, making it an excellent choice for precision machinery and industrial equipment requiring reliable, long-lasting operation.
1217KJC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1217 | Standard bearing series designation, indicating the core dimensions (85mm bore). |
| K | Indicates a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
| JC3 | Specifies the radial internal clearance group. C3 denotes a clearance greater than normal, suitable for applications with thermal expansion or where interference fits are used. |
1217KJC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact construction provides significantly greater rigidity compared to single row bearings, enabling it to support substantial combined radial and axial loads simultaneously.
- Optimized for Precision Mounting: The tapered bore (1:12) allows for precise axial positioning and secure clamping on a shaft, ensuring minimal runout and enhanced operational accuracy.
- Enhanced Operational Range: The C3 internal clearance accommodates thermal expansion from high-speed operation or interference fits, preventing premature failure due to excessive preload.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, and a steel cage, ensuring high durability and a long service life under demanding conditions.
- Ready-to-Install: The bearing is pre-lubricated from the factory, facilitating immediate installation and initial operation.
1217KJC3 Bearing Typical Application Areas
This bearing is ideally suited for industrial applications requiring robust performance and high precision, including:
- Industrial Gearboxes and power transmission systems.
- Vibrating Screens and other material handling equipment.
- Agricultural Machinery such as tractor transmissions.
- Pump and Compressor shafts.
- Heavy-duty industrial fans and blowers.
