1308L1 Bearing Product Overview & Core Advantages
The 1308L1 is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and reliable performance under combined radial and axial loads. Its open design and brass cage construction facilitate high-speed operation, while its precision-ground chrome steel components ensure dimensional stability and long service life. This bearing is pre-lubricated for immediate use and is ideal for compact, high-performance assemblies where space is at a premium.
1308L1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Standard bore diameter series designation (40mm bore, 90mm OD). |
| L1 | Indicates a specific internal clearance group (CN - Normal clearance). |
| Open | No contact seals or shields, allowing for higher speeds and easier re-lubrication. |
1308L1 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior radial and axial stiffness, enabling it to handle significant combined loads from multiple directions simultaneously.
- High-Speed Capability: The lightweight and durable brass cage ensures stable operation and guides the balls effectively, contributing to the high limiting speed of 9,500 rpm.
- Precision & Durability: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers excellent wear resistance and fatigue life. The cylindrical bore with tight tolerances ensures precise shaft fitment.
- Standard Internal Clearance: The CN (Normal) radial internal clearance makes it suitable for a wide range of common industrial applications and operating conditions.
1308L1 Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General machinery requiring robust support for combination loads
