11207TN Bearing Product Overview & Core Advantages
The 11207TN is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design without seals, allowing for optimal lubrication flow and making it suitable for high-speed operation. Its double row construction provides superior rigidity and enables it to accommodate combined loads (radial and axial loads) simultaneously. The use of a nylon cage contributes to its excellent high-speed performance, low friction, and quiet operation, making it an ideal choice for demanding industrial applications.
11207TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 11207 | Basic bearing designation indicating a double row angular contact ball bearing with specific dimensions (35mm bore, 72mm OD) |
| TN | Indicates a nylon cage (polymer cage) which provides excellent high-speed capability, reduced friction, and quieter operation |
11207TN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides enhanced stiffness and enables the bearing to handle significant radial loads and moderate axial loads in both directions, making it suitable for applications with combined loading conditions.
- High-Speed Performance: The TN nylon cage ensures smooth operation at high rotational speeds (limiting speed: 5,600 rpm) with minimal friction and heat generation.
- Precision Engineering: Manufactured with tight dimensional tolerances and chrome steel components for consistent performance and long service life in precision applications.
- Optimized Internal Clearance: Features CN radial internal clearance as standard, providing balanced performance for most industrial applications.
11207TN Bearing Typical Application Areas
- Machine Tool Spindles and precision machining equipment
- Industrial Pumps and compressor systems
- Electric Motors requiring high-speed operation
- Material Handling Equipment and conveyor systems
- Precision Instruments and testing equipment
- Agricultural Machinery and automotive applications
