1310L1 Bearing Product Overview & Core Advantages
The 1310L1 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant radial loads while maintaining operational stability. Its compact construction and robust brass cage make it an ideal choice for machinery where space constraints and high reliability are critical factors.
1310L1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310 | Standard bearing series designation, indicating principal bearing dimensions (50mm bore, 110mm OD, 27mm width). |
| L1 | Suffix indicating a specific internal clearance group. In this case, it corresponds to the CN clearance group as per specification. |
1310L1 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior stiffness, enabling the bearing to effectively support substantial radial loads and moderate axial loads in both directions, making it suitable for combined loading conditions.
- Optimized for Performance: The precision-ground chrome steel rings and balls ensure consistent operation and long service life. The robust brass cage provides excellent guidance for the rolling elements, contributing to smooth operation and high limiting speed capabilities.
- Pre-Lubricated & Ready-to-Install: The bearing is factory-filled with lubricant, simplifying installation and providing immediate protection against wear during the initial run-in period, reducing maintenance requirements.
- Standard Internal Clearance: The CN radial internal clearance is a standard grade suitable for a wide range of general industrial applications, ensuring predictable performance and thermal expansion management.
1310L1 Bearing Typical Application Areas
This bearing is commonly specified in:
- Industrial Gearboxes and Power Transmission Systems
- Electric Motors and Generators of medium size
- Material Handling Equipment such as conveyor pulleys
- General Industrial Machinery requiring robust and reliable double row ball bearing support
