S63805zz Bearing Product Overview & Core Advantages
The S63805zz is a precision miniature ball bearing designed for applications demanding high reliability and compact design. As a single row deep groove ball bearing, it excels at handling primarily radial loads and is constructed entirely from stainless steel for enhanced corrosion resistance. Its key advantages include a high limiting speed and operation across a wide temperature range, making it an ideal component for compact, high-performance mechanisms.
S63805zz Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| S6 | Indicates a bearing series with specific internal design optimizations. |
| 3805 | Specifies the bearing dimensions: 5mm bore, 8mm outside diameter, and 3mm width. |
| zz | Denotes shielded on both sides. These non-contact metal shields protect against contamination while minimizing friction, contributing to the high limiting speed. |
S63805zz Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single row construction and miniature bearing dimensions (5x8x3mm) allow for integration into space-constrained designs without sacrificing performance.
High-Speed Capability: The combination of a stainless steel cage, deep groove raceway geometry, and low-friction shields (zz) enables a high limiting speed of 18,920 rpm, suitable for demanding rotational applications.
Corrosion Resistance & Durability: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing offers excellent resistance to rust and corrosion, ensuring long-term reliability in harsh environments.
Precision Performance: Built to ABEC-1 tolerance class with a standard C0 radial internal clearance, it provides consistent and smooth operation, which is critical for precision instruments.
S63805zz Bearing Typical Application Areas
- Precision Instruments: Optical encoders, measuring devices, and laboratory equipment.
- Small Motors & Drives: Stepper motors, miniature DC motors, and fan motors.
- Office Automation: Printers, scanners, and copiers.
- Medical Devices: Small surgical handpieces, dental tools, and diagnostic equipment.
- Robotics: Joints and actuators in small-scale robotic arms and drones.
