1218-TVH-C3 Bearing Product Overview & Core Advantages
The 1218-TVH-C3 is a metric double row angular contact ball bearing designed for applications requiring high radial load capacity and operational reliability. Featuring an open construction and manufactured from high-grade chrome steel, this bearing is engineered for precision and durability. Its C3 radial internal clearance makes it particularly suitable for applications where thermal expansion is a factor, ensuring consistent performance under varying operating temperatures. The bearing comes pre-lubricated, offering immediate readiness for installation and initial operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1218 | Standard bearing designation indicating size series and bore diameter (90mm) |
| TVH | Manufacturer-specific designation for construction and internal design features |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion requirements |
1218-TVH-C3 Bearing Structural Features & Performance Benefits
Double Row Design: The double row ball bearing construction provides enhanced radial load capacity and improved rigidity compared to single row designs, making it ideal for applications requiring stable rotational characteristics.
Nylon Cage: The nylon cage material contributes to smooth operation at high speeds (up to 5,300 rpm), offering excellent strength-to-weight ratio and reduced friction.
Optimized Internal Clearance: The C3 clearance specification ensures reliable performance in applications where thermal expansion occurs, preventing binding and maintaining proper preload conditions.
Precision Manufacturing: Manufactured from chrome steel with tight dimensional tolerances, ensuring consistent performance and long service life in demanding industrial environments.
