1208-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1208-K-TVH-C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Featuring a tapered bore (1:12) for precise shaft mounting, this metric bearing offers excellent radial load capacity while maintaining compact dimensions. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. Manufactured with chrome steel rings and balls, and a nylon cage, it delivers durable performance in demanding industrial environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard bearing size designation (40mm bore, 80mm OD) |
| K | Tapered bore with 1:12 ratio |
| TVH | Nylon cage (polyamide) design |
| C3 | Greater than normal radial internal clearance |
1208-K-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness and stability, 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 static load rating of 1564 lbf, this bearing effectively handles combined radial and axial loads in both directions.
Optimized Performance: The nylon cage (TVH) enables smooth operation at limiting speeds up to 11,000 rpm, while the tapered bore ensures secure mounting and proper internal clearance adjustment.
Thermal Compensation: The C3 clearance accommodates thermal expansion in applications with elevated operating temperatures or interference fits, preventing premature failure.
