6004-Z/MT Bearing Product Overview & Core Advantages
The 6004-Z/MT is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features a shielded design on one side, providing effective protection against contamination while maintaining high operational reliability. Engineered from high-grade Chrome Steel, it offers a robust solution for handling significant radial loads. Its compact dimensions (20mm bore, 42mm OD, 12mm width) and ABEC 1 | ISO P0 tolerance class make it a versatile and cost-effective choice for a wide range of industrial machinery, balancing performance with value.
6004-Z/MT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| -Z | Denotes a shielded design on one side. This shield helps to retain lubrication and exclude larger contaminants like dust, enhancing bearing life without significantly increasing friction. |
| /MT | Indicates the bearing is pre-lubricated with a specific high-quality grease. This provides immediate, maintenance-free operation from installation and is suitable for the specified temperature range of -30°C to 120°C. |
6004-Z/MT Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The deep groove raceway and Chrome Steel construction enable high radial dynamic load rating (2113 lbf) and radial static load rating (1135 lbf), making it suitable for applications with substantial radial forces.
- Optimized for Speed: With a limiting speed of 17,000 rpm, this bearing is engineered for high-speed operation. The combination of the precision-ground raceways and the effective shielded design contributes to stable performance at elevated rotational speeds.
- Simplified Maintenance & Longevity: The integrated shield and factory-applied grease lubrication (/MT) create a sealed, pre-lubricated unit. This design significantly reduces the need for re-lubrication, offering a maintenance-free solution and extending service intervals.
- Precision and Consistency: Manufactured to ABEC 1 | ISO P0 tolerance standards with a standard CN radial internal clearance, this bearing ensures reliable, consistent performance and smooth operation in general industrial applications.
6004-Z/MT Bearing Typical Application Areas
