1308J Bearing Product Overview & Core Advantages
The 1308J metric double row angular contact ball bearing is engineered for applications requiring robust support for combined radial and axial loads. Its double row design provides superior rigidity and load-carrying capacity in a compact cross-section, making it ideal for high-precision machinery. Manufactured from high-grade chrome steel and featuring a steel cage, this bearing delivers reliable performance and extended service life in demanding operational environments.
1308J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Standard bearing series designation, indicating a 40mm bore, 90mm OD, and 23mm width. |
| J | Suffix denoting a CN group radial internal clearance as standard. |
| (Open) | No seal suffix indicates an open bearing design, suitable for systems with external lubrication. |
1308J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides exceptional stiffness and enables the bearing to support significant combined loads (radial and axial) simultaneously, making it suitable for applications with complex loading conditions.
- Optimized for Precision: Manufactured with tight dimensional tolerances on the bore diameter (40 mm), outside diameter (90 mm), and width (23 mm) to ensure precise fit and smooth operation in high-accuracy assemblies.
- Robust Material Construction: Components made from chrome steel offer high hardness and wear resistance, while the steel cage ensures dimensional stability and durability at the specified limiting speed of 9,500 rpm.
- Standard Internal Clearance: The J suffix confirms a CN normal radial internal clearance, which is versatile for a wide range of common operating conditions and fits.
1308J Bearing Typical Application Areas
This double row angular contact ball bearing is commonly specified in:
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust, high-capacity bearings
