SF692xzz Bearing Product Overview & Core Advantages
The SF692xzz is a miniature single row deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its shielded design provides effective protection against contaminant ingress while maintaining low running torque. This bearing is designed to handle primarily radial loads and is characterized by its high limiting speed and ABEC1 precision class, making it ideal for applications demanding smooth operation and long service life in constrained spaces.
SF692xzz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| SF692 | Basic bearing series designation, indicating a specific miniature bearing design. |
| x | Placeholder for specific bore size variations within the series. |
| zz | Denotes non-contact shields on both sides. This configuration offers excellent protection from dust and debris while minimizing friction and heat generation, contributing to the high limiting speed. |
SF692xzz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 2.5 mm and a weight of only 0.68 g, this bearing is optimized for miniature and portable devices where space and weight are critical constraints.
- Stainless Steel Construction: All components, including rings, balls, cage, and shields, are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments or washdown applications.
- High-Speed Capability: The combination of a stainless steel cage, low-friction non-contact shields, and optimized internal geometry enables a high limiting speed of 56,700 rpm.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and quiet operation, reduced vibration, and consistent performance.
- Radial Load Capacity: Engineered to handle radial dynamic loads up to 66 lbf, providing reliable support in compact assemblies.
SF692xzz Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical and Dental Instruments: Used in handheld surgical tools, dental handpieces, and diagnostic equipment due to its compact size, corrosion resistance, and reliability.
- Office Automation Equipment: Suitable for scanners, printers, and small fans.
- Robotics and RC Models: Provides precise motion control in small joints, gears, and drive systems.
- Precision Instrumentation: Applied in optical encoders, gauges, and other sensitive measuring devices.
