1212-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1212-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 exceptional rigidity and stability. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where preload conditions exist. Manufactured from chrome steel with a nylon cage, it offers reliable performance in demanding industrial environments.
1212-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1212 | Basic bearing designation indicating metric dimensions |
| K | Tapered bore with 1:12 ratio for precise shaft fitting |
| TVH | Designates specific internal design features and nylon cage construction |
| C3 | Radial internal clearance greater than normal for thermal expansion applications |
1212-K-TVH-C3 Bearing Structural Features & Performance Benefits
Double Row Design: The double row ball bearing configuration provides enhanced radial load capacity and superior rigidity compared to single row bearings, making it ideal for applications requiring stable rotational accuracy.
Tapered Bore Mounting: The 1:12 tapered bore ensures secure interference fit on tapered shafts, preventing slippage and maintaining precise alignment under heavy loads and high speeds.
Optimized Cage Design: The nylon cage offers excellent performance at limiting speeds up to 8,000 rpm, providing reduced friction, lower operating temperatures, and quieter operation.
Precision Manufacturing: Manufactured from high-quality chrome steel with tight dimensional tolerances (bore: -0.015mm to 0, OD: -0.015mm to 0) ensuring consistent performance and long service life.
