E2.6303-2Z/C3 Bearing Product Overview & Core Advantages
The E2.6303-2Z/C3 is a metric single row deep groove ball bearing engineered for high performance and reliability. This shielded bearing is designed to primarily accommodate radial loads efficiently. Its key advantages include a C3 radial internal clearance, making it suitable for applications with thermal expansion or demanding operating conditions. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and long service life in a compact and robust design.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| E2.6303 | Basic bearing designation, indicating a specific single row deep groove ball bearing series with a 17mm bore, 47mm OD, and 14mm width. |
| 2Z | Signifies that the bearing is shielded on both sides. These non-contact steel shields protect the internal components from contamination by solid particles, enhancing bearing life and reliability. |
| /C3 | Indicates a greater than normal radial internal clearance. This C3 clearance is ideal for applications where thermal expansion of the shaft or housing is expected, or where heavy loads and high speeds generate significant heat. |
E2.6303-2Z/C3 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing offers high strength, durability, and resistance to wear.
- Effective Contamination Protection: The 2Z shields on both sides effectively retain the factory-applied grease and exclude larger contaminants, making the bearing suitable for environments where liquid seals are not required.
- Optimized Internal Clearance: The C3 radial clearance provides operational stability under varying thermal conditions, preventing premature failure due to excessive preload from thermal expansion.
- High-Speed Capability: With a limiting speed of 17,000 rpm, the bearing is capable of operating in high-speed applications, supported by its precision-ground components and optimized internal geometry.
- Precision & Reliability: Conformance to ABEC 1 | ISO P0 tolerance class ensures dimensional accuracy and smooth, consistent operation, which is critical for reducing vibration and noise.
