E2.626-2Z/C3 Bearing Product Overview & Core Advantages
The E2.626-2Z/C3 is a metric single row deep groove ball bearing engineered for precision radial load applications. This shielded bearing delivers high reliability and consistent performance in compact spaces. Its ABEC 1 (ISO P0) tolerance class ensures smooth operation, while the C3 radial internal clearance provides optimal performance under thermal expansion conditions. Manufactured entirely from chrome steel, it offers excellent durability for industrial applications requiring dependable rotational accuracy.
Model Code Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| E2.626 | Basic bearing designation | Defines standard dimensions: 6mm bore, 19mm OD, 6mm width |
| 2Z | Shielded on both sides | Provides contamination protection while maintaining low torque |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed or high-temperature applications |
E2.626-2Z/C3 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables excellent radial load capacity (526 lbf dynamic rating) while accommodating moderate axial loads in both directions.
Shielded Construction: Both sides feature non-contact steel shields that retain lubricant and exclude larger contaminants, extending service life without significant speed reduction.
Precision Manufacturing: Chrome steel construction throughout (rings, balls, cage) ensures dimensional stability and wear resistance. The ABEC 1 precision class guarantees consistent running accuracy for smooth operation.
Optimized Clearance: The C3 internal clearance prevents preload in applications where thermal expansion occurs, maintaining optimal performance across the operating temperature range (-30° to 120°C).
