1308 K Bearing Product Overview & Core Advantages
The 1308 K 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 high-precision machinery and applications where space constraints and high rigidity are critical. The open design, when paired with appropriate external sealing, facilitates efficient lubrication management.
1308 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Standard bearing series designation, indicating the core bearing dimensions (40 mm bore, 90 mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio. This allows for precise axial positioning and a tight interference fit on the shaft, enhancing stability. |
1308 K Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior high rigidity, enabling the bearing to withstand substantial radial dynamic loads (7605 lbf) and radial static loads (2520 lbf). This makes it exceptionally capable of handling combined loads.
Precision & Speed: Manufactured from high-grade Chrome Steel for both rings and balls, the bearing ensures durability and consistent performance. The lightweight Nylon cage contributes to smooth operation and allows for a high limiting speed of 9,500 rpm, suitable for many high-speed applications.
Mounting & Internal Clearance: The tapered bore facilitates straightforward and secure mounting on adapter sleeves or withdrawal sleeves. The standard CN radial internal clearance is suitable for a wide range of operating conditions.
1308 K Bearing Typical Application Areas
The 1308 K bearing is widely used in various industrial sectors due to its robust construction and high load capacity. Key applications include:
- Industrial Gearboxes and power transmission systems.
- Vibrating Screens and other material handling equipment.
- Agricultural Machinery such as tractor transmissions.
- Pump and Compressor shafts.
- General machinery requiring a high rigidity, double row bearing solution.
