| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel bearing series |
| 619 | Deep Groove Ball Bearing series with extremely low cross-section |
| 1.5 | Nominal bore diameter of 1.5 mm |
| R | Flanged outer ring design for simplified axial location and mounting |
W 619/1.5 R Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With an ultra-small bore diameter of 1.5 mm and a total weight of just 0.0002 kg, this bearing is engineered for miniature applications where every milligram and millimeter counts.
- High-Speed Capability: The optimized stainless steel cage and open construction contribute to a high limiting speed of 120,000 rpm, enabling smooth operation in fast-rotating assemblies.
- Corrosion Resistance & Material Integrity: Manufactured entirely from stainless steel (rings, balls, and cage), the bearing offers excellent corrosion resistance and is suitable for a wide temperature range from -30°C to 120°C.
- Simplified Mounting with Flange: The flanged outer ring (flange outer diameter: 6.5 mm) ensures precise and secure axial positioning within a housing, reducing assembly complexity and cost.
- Precision Tolerance: Manufactured to P0 tolerance class and standard CN radial internal clearance, it provides consistent, high-precision performance suitable for sensitive instrumentation.
W 619/1.5 R Bearing Typical Application Areas
This miniature flanged bearing is ideally suited for:
- Precision Miniature Motors (e.g., in drones, medical devices)
- Small Instrumentation and Gauges
- Office Automation Equipment (e.g., scanners, printers)
- Optical and Laser Positioning Systems
- Various low-load, high-speed mechanisms in the electronics and consumer goods industries.
