W 619/1 R Bearing Product Overview & Core Advantages
The W 619/1 R is a miniature deep groove ball bearing designed for applications requiring compact dimensions and reliable performance in confined spaces. This single row bearing excels at handling primarily radial loads and features an open design for versatile application potential. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its extremely small size and low weight make it ideal for high-precision instruments and compact mechanisms demanding high reliability.

| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Deep Groove Ball Bearing |
| 619 | Bearing series, indicating a very light series with a thin cross-section. |
| 1 | Bore diameter code for a 1 mm bore. |
| R | Flange on the outer ring for simplified mounting and axial location. |
W 619/1 R Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 1 mm and a total weight of just 0.0001 kg, this bearing is engineered for the most space-constrained applications, minimizing system inertia.
- Flanged Outer Ring: The integrated flange (outer diameter: 5 mm) facilitates easy and precise axial positioning within a housing, simplifying assembly and improving structural integrity.
- Stainless Steel Construction: All components—rings, balls, and cage—are made from stainless steel, providing superior corrosion resistance and enabling use in harsh environments or where cleanliness is critical.
- Open Seal Type: The open design allows for high-speed operation (limiting speed of 140,000 rpm) and is suitable for applications where external sealing is provided or where the bearing will be re-lubricated as part of a system.
- Standard Clearance & Tolerance: Features a CN radial internal clearance and P0 tolerance class, making it a robust and versatile choice for a wide range of general precision applications.
W 619/1 R Bearing Typical Application Areas
- Miniature and Precision Instruments: Ideal for small gauges, optical devices, and laboratory equipment.
- Small Motors and Gearboxes: Used in micro-DC motors, stepper motors, and miniature planetary gearheads.
- Office Automation Equipment: Suitable for printers, scanners, and copiers where compact ball bearings are required.
- Medical and Dental Devices: Applicable in handheld surgical tools and diagnostic apparatuses due to its small bearing dimensions and stainless steel material.
- Robotics and RC Models: Used in small joints, actuators, and drone mechanisms.
