1211-TVH Bearing Product Overview & Core Advantages
The 1211-TVH is a double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design and is pre-lubricated, enabling it to accommodate significant radial loads and moderate axial loads in both directions simultaneously. Its compact construction and robust design make it an ideal choice for high-reliability machinery where space is at a premium and operational stability is critical.
1211-TVH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| TVH | Denotes a Nylon (Polyamide) cage and signifies that the bearing is filled with a specific lubricating grease. This combination contributes to lower friction, quieter operation, and is suitable for a wide temperature range. |
1211-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior stiffness, enabling the bearing to effectively support substantial radial dynamic loads (6210 lbf) and combined loads.
- Optimized for Performance: The lightweight Nylon cage ensures smooth operation at the specified limiting speed (9,000 rpm), reduces inertial forces, and is conducive to lower operating temperatures.
- Ready-to-Install Convenience: The bearing is pre-lubricated, facilitating immediate installation and initial operation without the need for additional greasing, streamlining the assembly process.
- Precision Dimensions: Manufactured with tight bore and outside diameter tolerances, this bearing ensures precise fit and reliable performance in demanding applications.
1211-TVH Bearing Typical Application Areas
This bearing is well-suited for a variety of industrial applications, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable bearing solutions.
