S692xzz Bearing Product Overview & Core Advantages
The S692xzz is a miniature deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, this single row bearing is designed to handle primarily radial loads and is shielded (ZZ) on both sides to retain lubrication and exclude contaminants. Its key advantages include a compact design with a 2.5 mm bore, excellent corrosion resistance, and suitability for high-speed operation up to 56,700 rpm, making it ideal for high-precision, high-reliability miniature systems.
S692xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 692 | The bearing series, indicating a very small, ultra-light series with a 2.5 mm bore diameter. |
| ZZ | Non-contact steel shields on both sides. This configuration protects the bearing interior from large particulate contaminants and helps retain lubricant, contributing to a longer service life with minimal maintenance. |
S692xzz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of just 2.5mm (bore) x 7mm (OD) x 3.5mm (width) and a weight of only 0.55g, this bearing is optimized for space-constrained miniature assemblies.
- High-Speed Capability: The combination of a stainless steel cage, seven precision balls, and a MC3 radial internal clearance enables a high limiting speed of 56,700 rpm, making it a true high-speed bearing in its class.
- Corrosion Resistance: All components, including rings, balls, cage, and shields, are made from 300 series stainless steel, ensuring reliable performance in humid or mildly corrosive environments.
- Precision Performance: Manufactured to ABEC1 tolerance class, this precision bearing provides consistent running accuracy and low noise and vibration, which is critical for sensitive applications.
S692xzz Bearing Typical Application Areas
This miniature deep groove ball bearing is ideally suited for:
- Precision Instruments: Optical encoders, gyroscopes, and laboratory equipment.
- Small Motors: Stepper motors, coreless motors, and miniature DC motors.
- Medical Devices: Surgical hand tools, dental drills, and miniature pumps.
- Office Automation: High-speed scanner mechanisms and precision guides.
- Robotics: Miniature joints, sensors, and drone gimbal systems.
