1213K Bearing Product Overview & Core Advantages
The 1213K is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation. Featuring a tapered bore (1:12) and open construction, this precision bearing is designed to accommodate combined loads, offering excellent performance in demanding environments. Its compact design and robust construction make it an ideal choice for high-reliability machinery.
1213K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Standard bearing series designation, indicating the bearing dimensions (65mm bore, 120mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
1213K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior stiffness and enables the bearing to support significant radial loads and moderate axial loads in both directions.
- Precision Tapered Bore: The K-suffix tapered bore allows for precise axial positioning and secure fit on a shaft, eliminating internal clearance and enhancing system stability.
- Optimized Cage & Material: The Nylon cage contributes to smooth operation, low friction, and is suitable for high-speed applications. The chrome steel rings and balls ensure high durability and long service life.
- Standard Internal Clearance: Supplied with a CN group radial internal clearance, making it suitable for a wide range of standard operating conditions.
1213K Bearing Typical Application Areas
This bearing is commonly used in:
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Pump and Compressor Systems
- General Industrial Machinery requiring a robust, double row bearing solution.
