1208-K C/3 Bearing Product Overview & Core Advantages
The 1208-K C/3 is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and precise operation. Its double row design provides superior support, enabling it to handle significant combined loads—both radial and axial forces—simultaneously. Featuring a 1:12 tapered bore for secure shaft mounting and a nylon cage for smooth, high-speed operation, this bearing is an excellent choice for high-reliability machinery. Pre-lubricated and with a CN radial internal clearance, it offers consistent performance right out of the box.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard bore diameter (40 mm) and outside diameter (80 mm) series. |
| K | Indicates a tapered bore with a 1:12 ratio for precise interference fit on the shaft. |
| C | Specifies the internal radial clearance group, in this case, CN (Normal clearance). |
| 3 | Denotes the cage type, which is a lightweight and durable nylon cage. |
1208-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides exceptional stiffness, effectively resisting operational deflections. This design enables it to support substantial radial dynamic load ratings of 4478 lbf and handle combined loads with high stability.
- Optimized for High-Speed Operation: The lightweight nylon cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 11,000 rpm. This makes it a capable high-speed bearing.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, secure fit on a tapered shaft adapter, eliminating internal clearance and enhancing rotational accuracy.
- Ready-to-Use & Durable: The bearing comes pre-lubricated and features an open design, making it suitable for integrated lubrication systems. Manufactured from chrome steel, it offers excellent durability and a wide operating temperature range from -30°C to 110°C.
1208-K C/3 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for applications requiring robust performance and high precision, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Various types of Transmission Systems
