Product Overview and Core Advantages
The 61900-2Z is a metric miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Featuring a single row design with stainless steel construction throughout (rings, balls, and cage), this bearing offers excellent corrosion resistance. A key advantage is its shielded (2Z) design on both sides, which effectively retains lubricant and excludes contaminants, enhancing operational life in demanding environments. It is engineered to primarily handle radial loads efficiently and is suitable for applications where space is limited but high reliability is essential.
S689zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61900 | Basic bearing series designation, indicating a miniature deep groove ball bearing with a 9mm bore. |
| -2Z | Signifies non-contact shields on both sides of the bearing. This provides good protection against contamination while maintaining low friction and allowing for high limiting speeds. |
Structural Features and Performance Benefits
- High Precision and Rigidity: Manufactured to ABEC1 tolerance class, ensuring consistent running accuracy. The deep groove raceway and stainless steel cage contribute to stable operation and good bearing rigidity.
- Optimized Load Capacity: The design is optimized for radial dynamic load (228 lbf) and radial static load (108 lbf) handling, making it suitable for various light to moderate load applications.
- High-Speed Capability: With a limiting speed of 32,400 rpm, this bearing is capable of high-speed operation, ideal for precision spindles and small motors.
- Corrosion Resistance and Longevity: The use of stainless steel for all critical components provides excellent resistance to rust and corrosion. The MC3 radial internal clearance (0.002mm to 0.013mm) is suited for a wide range of operational conditions.
- Compact and Lightweight: With compact bearing dimensions (9mm bore, 17mm OD, 5mm width) and a low weight of 4.38g, it is ideal for applications where minimizing size and mass is critical.
S689zz Bearing Typical Application Areas
This bearing is commonly used in:
- Precision Instruments and optical devices
- Small electric motors and fans
