1209-TVH-C3 Bearing Product Overview & Core Advantages
The 1209-TVH-C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and operational reliability. This precision bearing is engineered to accommodate combined loads, simultaneously handling significant radial forces and moderate axial loads in both directions. Its compact design, featuring a 19 mm width, makes it ideal for space-constrained applications. The bearing is pre-lubricated and features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where higher operational temperatures are expected, ensuring consistent performance and high rigidity.
1209-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1209 | Standard bearing series designation indicating bearing dimensions: 45 mm bore, 85 mm OD, 19 mm width. |
| TVH | Indicates a Nylon cage (Polyamide cage), which contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
| C3 | Specifies a radial internal clearance greater than normal (C3 clearance). This is optimal for applications with shaft or housing fits that cause a reduction in clearance, or where operational heat generation is expected. |
1209-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior high rigidity and enables the bearing to support substantial radial dynamic load ratings of 5152 lbf and handle combined loads effectively.
High-Speed Performance: The lightweight Nylon cage (TVH) minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 11,000 rpm, making it an excellent high-speed bearing.
Optimized for Demanding Conditions: The specified C3 radial internal clearance ensures reliable performance under conditions of thermal expansion or interference fits, preventing premature failure due to excessive preload.
Durable Material Construction: Manufactured from Chrome Steel for both rings and balls, this bearing offers high wear resistance and long service life under demanding operational conditions.
1209-TVH-C3 Bearing Typical Application Areas
The 1209-TVH-C3 is ideally suited for a wide range of industrial machinery requiring robust performance and reliability. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Pumps and Compressors
