SF682zz Bearing Product Overview & Core Advantages
The SF682zz is a miniature deep groove ball bearing designed for applications demanding compact size, reliable performance, and corrosion resistance. As a single row, shielded bearing, it is optimized to handle primarily radial loads efficiently. Its all-stainless steel construction ensures excellent durability and protection against corrosion, making it a precision bearing suitable for high-reliability, small-scale mechanisms. The integrated shields retain lubrication and protect against contamination, contributing to long service life.
SF682zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| SF | Flanged Outer Ring |
| 68 | Series designation indicating specific bearing dimensions and cross-section. |
| 2 | Bore Diameter Code (2 mm) |
| zz | Non-Contact Shields on both sides. This provides effective protection against contaminants while minimizing friction, supporting the bearing's high-speed capability. |
SF682zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of just 2 mm and a weight of only 0.24 g, this bearing is ideal for space-constrained and weight-sensitive applications.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, cage, and shields), it offers superior performance in humid or corrosive environments.
- High-Speed Performance: The non-contact zz shields and optimized stainless steel cage contribute to a high limiting speed of 76,500 rpm, making it a capable high-speed bearing.
- Simplified Mounting: The flanged outer ring (SF prefix) aids in accurate axial location and simplifies installation within a housing.
- Precision & Reliability: Built to ABEC1 tolerance class, it ensures consistent running accuracy for smooth and quiet operation.
SF682zz Bearing Typical Application Areas
- Small DC Motors and Stepper Motors
- Precision Instruments and Optical Encoders
- Medical Devices and Dental Handpieces
- Radio-Controlled Models (Drones, Cars)
- Office Automation Equipment (Small printers, scanners)
- Miniature Gearboxes and Robotics
