6004-2Z/VK285 Bearing Product Overview & Core Advantages
The 6004-2Z/VK285 is a single row deep groove ball bearing featuring integral shielded protection. Engineered for radial load applications, this metric bearing delivers reliable performance in compact spaces with its 20 mm bore and 42 mm outside diameter. Its ABEC 1 | ISO P0 tolerance class ensures consistent operation, while the chrome steel construction provides excellent durability and corrosion resistance. The pre-lubricated design with VK285 grease offers immediate operation readiness and extended service life across a wide temperature range from -30° to 120°C.
6004-2Z/VK285 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Effective contamination protection while maintaining high rotational speeds |
| VK285 | High-performance lithium-based grease | Optimized for wide temperature range (-30° to 120°C) and extended lubrication life |
6004-2Z/VK285 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables excellent radial load capacity (2113 lbf dynamic, 1135 lbf static) while accommodating moderate axial loads in both directions.
Shielded Protection System: The 2Z shields provide effective sealing against contaminants without significant speed reduction, supporting limiting speeds up to 17,000 rpm.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 standards with CN clearance, ensuring smooth operation and reduced vibration in general industrial applications.
Material Excellence: All-steel construction using chrome steel for rings, balls, and cage delivers consistent performance and long service life under demanding conditions.
