6004-2Z/GJN Bearing Product Overview & Core Advantages
The 6004-2Z is a single row deep groove ball bearing designed for reliable performance in various industrial applications. This shielded bearing excels at handling radial loads and offers robust operation within its specified parameters. Its key advantages include a compact design, ABEC 1 precision for consistent operation, and the integration of shields (2Z) to protect against contamination. Manufactured from high-quality chrome steel, it provides a dependable solution for applications requiring moderate speeds and long service life.
6004-2Z/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6004 | Basic bearing series, indicating a metric, single row deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width. |
| 2Z | Specifies non-contact shields on both sides. This provides effective protection against coarse contaminants while minimizing friction, contributing to the bearing's limiting speed of 17,000 rpm. |
| /GJN | Indicates a specific radial internal clearance group. In this context, it corresponds to the standard CN clearance as per the provided specifications. |
6004-2Z/GJN Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and high-grade chrome steel construction for rings, balls, and cage ensure high dimensional stability and durability under radial dynamic load ratings of 2113 lbf.
- Effective Contamination Protection: The 2Z shields on both sides help to retain the initial lubrication and exclude larger particulate matter, enhancing bearing life in challenging environments.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing provides reliable running accuracy, low vibration, and smooth operation, which is critical for general machinery applications.
- Standard Internal Clearance: The CN radial internal clearance is suitable for a wide range of operating conditions and common fit scenarios.
