627-2Z/C3GJN Bearing Product Overview & Core Advantages
The 627-2Z/C3GJN is a metric single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its compact design and high-quality chrome steel construction ensure reliable operation, providing robust support for radial loads while maintaining smooth rotation. The inclusion of shields offers effective protection against contaminant ingress, enhancing service life.
627-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective protection against dust and debris while minimizing friction. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing premature failure. |
| GJN | Grease type and fill specification | Indicates the use of a specific high-performance grease suitable for the stated temperature range. |
627-2Z/C3GJN Bearing Structural Features & Performance Benefits
Single Row Deep Groove Design: The optimized raceway geometry enables the bearing to handle not only radial loads but also moderate axial loads in both directions, offering versatile load capacity.
Shielded Protection (2Z): The steel shields retain lubrication and effectively exclude contaminants, significantly extending the bearing's operational life and reducing maintenance needs.
C3 Internal Clearance: This greater radial clearance is critical for applications involving elevated operating temperatures or press-fits onto shafts, preventing binding and ensuring smooth, reliable performance.
Precision Manufacturing (ABEC 1 | ISO P0): Manufactured to standard precision tolerances, this bearing provides consistent performance, low noise, and low vibration for a wide range of industrial applications.
627-2Z/C3GJN Bearing Typical Application Areas
