11208TV Bearing Product Overview & Core Advantages
The 11208TV is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance. This precision bearing features an open design and is capable of accommodating combined loads, including significant radial loads and moderate axial loads in both directions. Its compact construction, with a nylon cage and pre-lubrication, makes it an excellent choice for high-speed operations and applications demanding dimensional stability and long service life.
11208TV Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 11208 | Basic designation indicating a double row angular contact ball bearing with 40mm bore diameter |
| TV | Designates nylon cage construction and specific internal design optimized for high-speed operation |
11208TV Bearing Structural Features & Performance Benefits
- High Rigidity: The double row design provides superior radial stiffness, making it ideal for applications requiring precise shaft positioning and minimal deflection under load.
- Enhanced Load Capacity: Engineered to handle combined loads effectively, with optimized raceway geometry that distributes stress evenly across both ball rows.
- High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, enabling stable operation at limiting speeds up to 5,000 rpm while maintaining proper ball guidance.
- Pre-Lubricated Design: Factory-applied lubrication ensures immediate operation and reduces maintenance requirements, with compatibility across a wide temperature range from -30°C to 110°C.
- Precision Dimensions: Manufactured with tight bearing size tolerances (bore: -0.012mm to 0, outside diameter: -0.013mm to 0) for consistent performance in precision applications.
11208TV Bearing Typical Application Areas
- Electric Motors and Industrial Gearboxes requiring high-speed operation and reliable performance
- Material Handling Equipment such as conveyor systems and automated guided vehicles
- Agricultural Machinery including tractor PTO systems and implement drives
- Industrial Pumps and Compressors where combined load capacity is critical
- General Industrial Machinery requiring durable, maintenance-free bearing solutions
