1212K Bearing Product Overview & Core Advantages
The 1212K is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Its metric design features a tapered bore (1:12) for secure shaft mounting. This bearing is engineered to accommodate significant radial loads while offering robust support, making it an ideal choice for precision machinery and high-reliability systems. Its compact cross-section and optimized internal geometry contribute to its exceptional performance.
1212K Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio. This design allows for precise axial positioning and a tight interference fit on the shaft, enhancing rotational accuracy and system rigidity. |
| (No Seal Suffix) | The bearing is supplied as an open type, allowing for customized lubrication solutions based on specific application requirements. |
1212K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior high rigidity, enabling the bearing to handle substantial radial dynamic loads (7020 lbf) and radial static loads (2745 lbf). This makes it exceptionally capable of managing combined loads.
- Optimized for Precision: The nylon cage ensures smooth operation at the specified limiting speed (8,000 rpm), reducing friction and wear. The standard CN radial internal clearance is suited for a wide range of industrial applications.
- Secure Mounting & Alignment: The tapered bore (1:12) facilitates easy and precise mounting on adapter sleeves or tapered shaft seats, ensuring excellent concentricity and minimizing runout.
- Material & Compliance: Manufactured from high-grade chrome steel for both rings and balls, ensuring durability and long service life. The bearing is compliant with ROHS and REACH regulations.
1212K Bearing Typical Application Areas
This bearing is ideally suited for applications where high radial load capacity and precise shaft location are critical. Common uses include:
- Industrial Gearboxes and Transmissions
- Material Handling Conveyor Systems
- Agricultural Machinery
- Vibrating Screens and Shakers
- Pillow Block and Flanged Bearing Units
