1208-TVH-C3 Bearing Product Overview & Core Advantages
The 1208-TVH-C3 is a double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. This metric bearing features an open design with cylindrical bore and is pre-lubricated for immediate operation. Its compact bearing dimensions (40mm bore, 80mm OD, 18mm width) provide space-saving solutions while delivering excellent radial load capacity. The C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used, ensuring stable operation across varying temperatures.
1208-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
| 1208 | Basic designation: 12 series, 08 bore size (40mm) | Standardized dimension reference |
| TVH | Nylon cage design (Polyamide cage) | Enables higher speeds, reduced friction, and quieter operation |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion, ideal for interference fits and elevated temperature applications |
1208-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, making it ideal for applications requiring precise shaft positioning and minimal deflection under load.
Enhanced Load Capacity: With a radial dynamic load rating of 4478 lbf and radial static load rating of 1564 lbf, this bearing effectively handles substantial radial loads while maintaining operational stability.
Optimized High-Speed Performance: The nylon cage (TVH) contributes to reduced mass and improved lubrication distribution, supporting operation at limiting speeds up to 11,000 rpm while maintaining smooth rotation.
Precision Engineering: Manufactured from chrome steel for both rings and balls, ensuring dimensional stability and long service life. The tight dimensional tolerances guarantee consistent performance in precision applications.
Thermal Compatibility: The C3 clearance accommodates differential thermal expansion between shaft and housing, preventing binding or excessive preload in applications with temperature variations from -30°C to 110°C.
