1213 K Bearing Product Overview & Core Advantages
The 1213 K is a metric double row angular contact ball bearing featuring a tapered bore design (1:12 ratio). Engineered for applications requiring high rigidity and superior radial load capacity, its compact double-row construction provides stable and precise rotational performance. This bearing is pre-lubricated and operates effectively within a wide temperature range, making it a reliable component for demanding industrial environments.
1213 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Standard bearing designation indicating bore diameter (65 mm), outside diameter (120 mm), and width (23 mm). |
| K | Denotes a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves for secure shaft fixation. |
1213 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides significantly increased radial dynamic load rating (7898 lbf) and stiffness compared to single-row designs, enabling stable operation under substantial loads.
- Tapered Bore Design: The "K" suffix indicates a tapered bore, which allows for precise axial clearance adjustment and a secure, interference fit when mounted with appropriate sleeves, minimizing inner ring creep.
- Optimized Cage & Speed: The Nylon cage contributes to smooth operation, low friction, and a high limiting speed (7,000 rpm), making it suitable for high-speed applications.
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, simplifying installation and providing immediate protection against wear during the initial run-in period.
- Material & Compliance: Manufactured from Chrome Steel for both rings and balls, ensuring durability and long service life. The bearing is compliant with ROHS and REACH regulations.
1213 K Bearing Typical Application Areas
- Industrial Gearboxes and Transmissions
- Material Handling Conveyor Systems
- Agricultural Machinery
- Electric Motors and Generators
- Vibrating Screens and Machinery
