1204-TVH Bearing Product Overview & Core Advantages
The 1204-TVH 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, enabling optimal lubrication access and heat dissipation. Its double row construction provides exceptional rigidity and the ability to handle combined loads (radial and bidirectional axial loads) simultaneously. Manufactured with chrome steel rings and balls, and a nylon cage, it delivers reliable performance in demanding environments.
1204-TVH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1204 | Standard bore diameter (20 mm), outside diameter (47 mm), and width (14 mm) |
| TVH | Nylon cage (TV), lubricated (H) for enhanced high-speed performance |
1204-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior stiffness, enabling stable operation under combined radial and axial loads.
- Optimized High-Speed Performance: The nylon cage (TV) reduces friction and inertia, supporting a limiting speed of 20,000 rpm.
- Precision Engineering: Tight dimensional tolerances on bore diameter, outside diameter, and width ensure consistent performance and easy integration.
- Durable Material Selection: Chrome steel components offer high wear resistance and durability, while the nylon cage contributes to smooth, quiet operation.
- Wide Temperature Range: Operates effectively from -30°C to 110°C, suitable for various industrial environments.
