S699zz Bearing Product Overview & Core Advantages
The 61900-2Z is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This metric precision bearing features stainless steel construction throughout (rings, balls, and cage) and integrated shielded seals (2Z), offering reliable radial load capacity and protection against contamination. Its compact dimensions (9mm bore, 20mm OD, 6mm width) and ABEC1 precision class make it ideal for applications demanding high reliability, smooth operation, and corrosion resistance.
S699zz Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 61900 | Standard designation for a deep groove ball bearing series with a 9mm bore diameter. |
| 2Z | Signifies the bearing is equipped with non-contact shields on both sides. This provides effective protection against dust and other contaminants while minimizing friction, contributing to the high limiting speed. |
S699zz Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All critical components—rings, balls, and cage—are manufactured from stainless steel, providing excellent corrosion resistance and durability, suitable for a wide temperature range of -30°C to 110°C.
- Optimized Radial Load Capacity: The deep groove raceway and complement of 8 precision balls enable efficient handling of radial dynamic loads up to 425 lbf and static loads up to 175 lbf.
- High-Speed Capability: The combination of a low-friction stainless steel cage, non-contact shields, and optimized internal geometry allows for a high limiting speed of 30,600 rpm.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group: 0.002mm to 0.013mm), ensuring smooth and precise rotation with minimal vibration.
S699zz Bearing Typical Application Areas
This versatile miniature bearing is engineered for use in:
- Small Precision Motors (e.g., drones, RC models, small fans)
- Medical and Dental Handpieces
- Office Automation Equipment (printers, scanners)
- Instrumentation and Measurement Devices
- Food Processing Equipment (due to its stainless steel construction and RoHS/REACH compliance)
