11210-TVH Bearing Product Overview & Core Advantages
The 11210-TVH is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and robust performance. Its double row ball construction provides superior rigidity and stability compared to single row designs, making it ideal for supporting substantial loads in a compact envelope. Manufactured from high-grade chrome steel with a nylon cage, this bearing is designed for reliable operation and is pre-lubricated for immediate use. Its open seal type allows for versatile re-lubrication options, suiting various industrial environments.
Model Code Breakdown
| Model Segment | Description | Technical Significance |
|---|---|---|
| 11210 | Basic Bearing Number | Indicates a metric series, double row angular contact ball bearing with a 50mm bore, 90mm OD, and 58mm width. |
| TVH | Contact Angle & Cage Designation | Denotes a specific contact angle optimized for combined loads and a nylon cage (TV) for quiet operation and high-speed capability. The 'H' suffix may indicate special internal clearance or heat stabilization. |
11210-TVH Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design significantly increases the bearing's rigidity and its ability to handle high radial dynamic loads (rated at 5962 lbf). This makes it exceptionally stable under heavy loads, reducing deflection and vibration.
Optimized for Speed & Efficiency: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 4,300 rpm. This ensures smooth operation and reduced energy consumption in demanding applications.
Precision & Reliability: Manufactured with tight dimensional tolerances on the bore diameter, outside diameter, and width, this bearing ensures precise fit and consistent performance. The standard CN radial internal clearance is suitable for a wide range of common operating conditions.
Material Integrity: Components made from chrome steel offer excellent hardness, wear resistance, and durability, ensuring a long operational lifespan under continuous use.
11210-TVH Bearing Typical Application Areas
The 11210-TVH double row angular contact ball bearing is ideally suited for a variety of industrial machinery and equipment where high radial load capacity and rigidity are paramount. Key application areas include:
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Electric Motors and Medium-Duty Machinery Spindles
