SF692x Bearing Product Overview & Core Advantages
The SF692x is a miniature single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its open design and flanged outer ring, which facilitates precise axial location during mounting. Its small footprint, high limiting speed, and compliance with ABEC1 precision standards make it an ideal component for high-speed, miniature electromechanical systems demanding high reliability.
SF692x Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF692x | Base model number for a specific series of flanged miniature bearings. |
| Open (Seal Type) | The bearing has no integral seals or shields, allowing for higher speeds and custom lubrication schemes. It requires a clean operating environment. |
| Flanged | The outer ring features a flange, simplifying housing design and providing positive axial location. |
SF692x Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 2.5 mm and a total weight of just 0.5 g, this bearing is engineered for space-constrained and weight-sensitive applications.
- High-Speed Capability: The open design and optimized internal geometry, including 7 precision balls, contribute to a high limiting speed of 56,700 rpm.
- Corrosion Resistance: All components, including rings, balls, and the stainless steel cage, are made from stainless steel, ensuring long-term performance in challenging environments.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and consistent operation.
- Radial Load Capacity: Engineered to handle significant radial dynamic load ratings (66 lbf) for its size, providing durable performance.
SF692x Bearing Typical Application Areas
This miniature flanged bearing is ideally suited for:
- Small Precision Motors (e.g., in drones, RC models)
- Medical and Dental Handpieces
