1218-TVH Bearing Product Overview & Core Advantages
The 1218-TVH is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing is engineered to accommodate combined loads—simultaneously handling significant radial loads and moderate axial loads in both directions. Its double row design provides high rigidity and stable rotational accuracy, making it ideal for applications requiring high reliability and precise shaft guidance. The open design, combined with a nylon cage and factory-applied lubrication, ensures smooth operation and is optimized for high-speed performance.
1218-TVH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| TVH | Indicates a Nylon (Polyamide) cage, snap-type design. This cage material contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
1218-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior radial and moment load stiffness compared to single row bearings. This design enables the bearing to effectively support combined loads, enhancing operational stability.
- Optimized for High Speeds: The lightweight nylon cage (TVH) minimizes centrifugal forces and ensures excellent guidance of the balls, allowing for a high limiting speed of 5,300 rpm.
- Precision & Longevity: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers high durability and resistance to wear. The standard CN radial internal clearance is suitable for a wide range of common industrial applications.
- Ready-to-Install: The bearing comes lubricated from the factory, simplifying installation and providing immediate protection upon startup.
1218-TVH Bearing Typical Application Areas
This bearing is well-suited for a variety of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
