1212 K Bearing Product Overview & Core Advantages
The 1212 K is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to support combined loads. Its metric design features a tapered bore (1:12) for secure shaft mounting. This bearing is engineered to handle significant radial loads while offering robust performance in demanding industrial environments. Its compact cross-section and precision construction make it an ideal choice for high-reliability machinery where space and performance are critical.
1212 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1212 | Standard bearing designation indicating a metric double row angular contact ball bearing with a 60 mm bore diameter. |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise axial positioning and a tight interference fit on the shaft. |
1212 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide exceptional stiffness, enabling the bearing to handle high radial dynamic load ratings (7020 lbf) and resist operational deformations.
- Optimized for Combined Loads: The angular contact design inherently manages combined loads (radial and axial), making it suitable for complex loading conditions.
- Precision & Stability: Manufactured from Chrome Steel with a Nylon cage, the bearing ensures smooth operation, low noise, and high-speed capability (limiting speed of 8000 rpm). The standard CN radial internal clearance is suited for a wide range of common applications.
- Ready-to-Use: The bearing is pre-lubricated, simplifying installation and providing immediate operational readiness.
1212 K Bearing Typical Application Areas
This precision bearing is widely used in various industrial sectors, including:
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Electric Motors
