S6704zz Bearing Product Overview & Core Advantages
The 61804-2Z stainless steel miniature bearing represents a precision single row deep groove ball bearing engineered for compact applications requiring reliable performance. This shielded bearing is constructed entirely from stainless steel, providing excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently while maintaining a minimal cross-section, making it ideal for space-constrained, high-speed assemblies where durability and consistent operation are critical.
S6704zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61804 | Series designation for a miniature deep groove ball bearing with a 20mm bore, 27mm OD, and 4mm width. |
| 2Z | Indicates the bearing is fitted with non-contact steel shields on both sides. This provides effective protection against contaminant ingress while minimizing friction and heat generation, contributing to the high limiting speed. |
S6704zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a width of just 4 mm and a weight of only 5.9 g, this bearing is the optimal solution for lightweight and miniaturized mechanisms.
- Corrosion Resistance: The use of stainless steel for all critical components (rings, balls, cage) ensures reliable operation in humid or mildly corrosive environments, expanding its application range.
- High-Speed Capability: The combination of the deep groove raceway, stainless steel cage, and non-contact 2Z shields allows for a high limiting speed of 7,600 rpm, suitable for demanding rotational applications.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a standard C0 radial internal clearance (0.006mm to 0.020mm), this bearing offers smooth and consistent running accuracy for general precision duties.
S6704zz Bearing Typical Application Areas
This versatile miniature bearing is commonly specified in:
- Small Electric Motors: Used in fans, drones, and precision tools.
- Medical Devices: Ideal for surgical handpieces, dental drills, and pump systems where corrosion resistance is paramount.
- Office Automation Equipment: Found in printers, scanners, and copiers.
- Instrumentation and Control Systems: Used in encoders, stepper motors, and guidance systems.
- Food Processing Equipment: Suitable for non-lubricated or easily cleaned environments due to its stainless steel construction.
