1306 M Bearing Product Overview & Core Advantages
The 1306 M is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and reliable performance under combined loads. Its double row design enables it to simultaneously support significant radial loads and bidirectional axial loads, making it an exceptionally compact and robust solution. Manufactured with precision tolerances and featuring a brass cage, this bearing is ideal for high-speed operations and scenarios requiring long-term operational stability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Standard bearing series designation, indicating a 30 mm bore diameter, 72 mm outside diameter, and 19 mm width. |
| M | Signifies that the bearing is supplied with brass cage and CN group radial internal clearance as standard. The "M" designation often represents a specific internal design and material combination for enhanced performance. |
1306 M Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact construction provides superior stiffness, enabling the bearing to handle substantial combined radial and axial loads from both directions without sacrificing performance.
- Optimized for High Speeds: The machined brass cage ensures excellent guidance of the balls, reduces friction, and contributes to a high limiting speed of 13,000 rpm, making it a true high-speed bearing.
- Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances on the bore diameter, outside diameter, and width, ensuring precise fit and reliable operation in precision applications.
- Standard Lubrication & Open Design: The bearing comes pre-lubricated and features an open seal type, allowing for custom re-lubrication strategies to suit specific operational environments and extend service life.
1306 M Bearing Typical Application Areas
The 1306 M double row angular contact ball bearing is widely used in various industrial sectors due to its robust design and high-performance characteristics. Key applications include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
