6003-2Z/GJN Bearing Product Overview & Core Advantages
The 6003-2Z is a metric single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantage lies in its ability to accommodate significant radial loads and moderate axial loads in both directions. The inclusion of shielded (2Z) construction on both sides protects the bearing's internals from contamination, enhancing its operational lifespan. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a cost-effective solution for applications requiring robust performance and consistent operation within a temperature range of -30° to 120 °C.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6003 | The basic bearing designation, indicating a single row deep groove ball bearing with a 17 mm bore, 35 mm outside diameter, and 10 mm width. |
| 2Z | Signifies that the bearing is shielded on both sides. These non-contact steel shields protect against the ingress of contaminants while minimizing friction, making the bearing suitable for cleaner environments. |
| /GJN | Indicates that the bearing is pre-lubricated with a specific grease type (GJN). This provides initial lubrication for the bearing's service life, contributing to its maintenance-free characteristic. |
6003-2Z/GJN Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for rings, balls, and cage, the 6003-2Z/GJN ensures high strength, durability, and resistance to wear.
- Versatile Load Capacity: The deep groove raceway and optimized internal geometry enable it to handle high radial dynamic load ratings (1349 lbf) and moderate axial loads from either direction.
- Contamination Protection: The double-shielded (2Z) design effectively seals the bearing against dust and other particles, significantly increasing reliability in challenging conditions.
- Maintenance-Free Operation: The combination of shields and factory-applied grease (GJN) eliminates the need for re-lubrication, reducing lifecycle costs and simplifying machine design.
- High-Speed Capability: With a limiting speed of 21,000 rpm, it is suitable for a variety of high-speed applications, supported by its precision construction and effective lubrication.
