619/5-2Z Bearing Product Overview & Core Advantages
The 619/5-2Z is a metric miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row bearing excels in handling radial loads efficiently while offering moderate speed capabilities. Its shielded design (2Z) provides effective contamination protection, and the pre-lubricated grease ensures immediate operation and long service life, making it an ideal choice for high-precision and high-reliability applications where space is constrained.
619/5-2Z Bearing Model Code Explained, Specifications & Naming Convention
The model designation 619/5-2Z breaks down as follows:
- 619: Series designation for miniature deep groove ball bearings.
- 5: Bore diameter of 5 mm.
- 2Z: Indicates the bearing is shielded on both sides. This provides protection against contaminants while allowing for relatively high-speed operation compared to sealed variants.
619/5-2Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P6 tolerance class and standard CN radial internal clearance, this bearing ensures precise running accuracy and stable operation under load, contributing to overall system rigidity.
- Optimized Load Capacity: With a dynamic load rating of 199 lbf and a static load rating of 75 lbf, it is engineered to handle significant radial loads for its compact size.
- Reliable High-Speed Operation: The combination of a stainless steel cage, precision-ground chrome steel components, and effective shielding enables a limiting speed of 50,000 rpm.
- Low Maintenance & Longevity: The double-shielded (2Z) construction retains the factory-applied grease, protecting against contamination and moisture, resulting in a maintenance-free bearing with a long operational life within its specified temperature range of -30°C to 120°C.
619/5-2Z Bearing Typical Application Areas
This bearing is ideally suited for compact and precision-driven applications, including:
- Small Electric Motors (e.g., in drones, precision tools)
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and Instrumentation
- Precision Gearboxes and Small Mechanisms
- Various miniature and instrument-grade machinery
