1207-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1207-K-TVH-C3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers high rigidity and stable performance under demanding conditions. Its open design allows for optimal lubrication management, while the C3 radial internal clearance accommodates thermal expansion in high-speed operations. Constructed from chrome steel with a nylon cage, it offers excellent durability and is suitable for precision machinery where reliability is critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Basic bearing designation indicating metric dimensions (35mm bore, 72mm OD) |
| K | 1:12 tapered bore for precise shaft fitting and secure mounting |
| TVH | Nylon cage design (polyamide cage) for reduced weight and smooth operation |
| C3 | Radial internal clearance greater than normal, suitable for thermal expansion in high-speed applications |
1207-K-TVH-C3 Bearing Structural Features & Performance Benefits
Double Row Design: The double row angular contact configuration provides high rigidity and superior radial load capacity compared to single row bearings, making it ideal for applications with significant radial forces.
Optimized Cage Technology: The nylon cage (TVH) ensures quiet operation, reduced friction, and excellent performance at high speeds, contributing to the bearing's 13,000 rpm limiting speed.
Tapered Bore Precision: The 1:12 tapered bore (K designation) enables precise axial positioning and secure mounting on tapered shafts, preventing slippage under heavy loads.
Enhanced Clearance Management: The C3 radial clearance accommodates thermal expansion during high-speed operation, maintaining optimal performance and extending service life.
Superior Material Construction: Manufactured from chrome steel for both rings and balls, this bearing delivers excellent wear resistance and durability in demanding industrial environments.
