1211-TVH-C3 Bearing Product Overview & Core Advantages
The 1211-TVH-C3 is a double row angular contact ball bearing engineered for applications requiring superior rigidity and the capacity to handle combined loads. Its metric design features an open construction, allowing for versatile lubrication options. This precision bearing is characterized by its optimized internal geometry and a C3 radial internal clearance, making it an ideal solution for arrangements where thermal expansion and high operational stability are critical.
1211-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| TVH | Designates a pressed steel cage (window type) and is often associated with a specific internal design optimized for high-speed operation. |
| C3 | Indicates a greater than normal radial internal clearance. This is essential for applications involving thermal expansion, high speeds, or where fits result in a reduction of internal clearance. |
1211-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides a significantly stiffer support structure compared to single row bearings, enabling it to withstand substantial radial loads and moment loads simultaneously.
- Optimized for Performance: The combination of a nylon cage and open seal type facilitates efficient lubrication distribution and lower friction, contributing to a high limiting speed of 9,000 rpm.
- Precision Engineering: Manufactured from high-grade chrome steel for both rings and balls, ensuring durability and consistent performance under demanding conditions. The C3 clearance offers operational flexibility in a wide temperature range.
- Bearing Dimensions & Design: With a bore diameter of 55 mm and an outside diameter of 100 mm, it offers a compact cross-section. The defined shoulder diameters ensure precise axial location.
1211-TVH-C3 Bearing Typical Application Areas
This bearing is suited for a wide range of industrial machinery where reliability under combined loads is paramount. Key applications include:
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Electric Motors
