1309-TVH-C3 Bearing Product Overview & Core Advantages
The 1309-TVH-C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and rigidity. This precision bearing excels at simultaneously handling significant combined loads, including radial forces and bidirectional axial loads, thanks to its optimized contact angle and double row design. Its open construction and C3 radial internal clearance make it particularly suitable for applications with thermal expansion considerations. Manufactured with chrome steel rings and balls, and featuring a lightweight nylon cage, it offers reliable performance in demanding industrial environments.
1309-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1309 | Basic bearing designation indicating bearing dimensions: 45mm bore, 100mm OD, 25mm width |
| TVH | Designates specific internal design features and contact angle optimization |
| C3 | Indicates greater radial internal clearance than normal (C0), suitable for applications with thermal expansion or where interference fits are used |
1309-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides enhanced stiffness and enables the bearing to handle substantial combined loads (radial dynamic load rating: 8775 lbf, static: 3015 lbf). This design ensures stable operation under varying load conditions.
Optimized High-Speed Performance: The nylon cage contributes to smooth operation at high rotational speeds (limiting speed: 8,500 rpm), reducing friction and heat generation while maintaining cage integrity.
Precision Engineering: Manufactured with chrome steel components and precise dimensional tolerances, this bearing delivers consistent performance and long service life in precision applications.
Thermal Compensation: The C3 clearance accommodates differential thermal expansion between the bearing and housing, preventing premature failure in applications with significant temperature variations (-30° to 110°C).
1309-TVH-C3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Electric Motors requiring high load capacity and rigidity
- Material Handling Equipment such as conveyor systems
- Agricultural Machinery components subject to heavy loads
- Industrial Pumps and compressors
