1308TN Bearing Product Overview & Core Advantages
The 1308TN is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling significant combined loads, including radial forces and bidirectional axial loads. Its compact bearing dimensions (40 mm bore, 90 mm OD, 23 mm width) and robust double-row construction deliver superior high rigidity, making it ideal for high-reliability machinery requiring stable and accurate shaft support.
1308TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Standard bearing series designation, indicating the core dimensions (40mm bore, 90mm OD). |
| TN | Indicates a Nylon (Polyamide) cage. This lightweight cage is ideal for high-speed applications, reducing friction, noise, and allowing for higher limiting speeds. |
1308TN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides a much stiffer support structure compared to single row bearings, effectively resisting operational deflections. This design enables it to carry substantial combined radial and axial loads from both directions, ensuring stable performance under complex loading conditions.
- High-Speed Performance: The lightweight TN cage minimizes centrifugal forces and ensures smooth operation at the high limiting speed of 9,500 rpm. The bearing is pre-lubricated to facilitate immediate startup and reliable operation.
- Precision & Durability: Manufactured from Chrome Steel for both rings and balls, this bearing offers high wear resistance and long service life. The standard CN radial internal clearance is suited for a wide range of common industrial applications.
1308TN Bearing Typical Application Areas
This bearing is engineered for use in a variety of industrial sectors, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
