6303-2Z/GJN Bearing Product Overview & Core Advantages
The 6303-2Z is a single row deep groove ball bearing featuring integral shielded construction. Engineered for reliable performance in radial load applications, this metric bearing offers a compact design with optimized internal geometry. Its ABEC 1 | ISO P0 tolerance class ensures consistent operation, while the shielded design provides effective contamination protection without significantly impacting limiting speed capabilities. The bearing comes pre-lubricated for immediate installation and long-term service.
6303-2Z/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 6303 | Basic bearing designation (17mm bore, 47mm OD, 14mm width) | Standard metric dimensions for easy interchangeability |
| 2Z | Non-contact steel shields on both sides | Effective contamination protection while maintaining high-speed capability |
6303-2Z/GJN Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The deep groove raceway design enables excellent radial load capacity while accommodating moderate axial loads in both directions.
Shielded Protection: Steel shields (2Z) provide effective sealing against contaminants while generating minimal friction, supporting operation at limiting speeds up to 15,000 rpm.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance standards with CN radial internal clearance for consistent performance in general industrial applications.
Material Excellence: All-steel construction using chrome steel for rings, balls, and cage ensures durability and reliable operation across the temperature range of -30°C to 120°C.
