SF695zz Bearing Product Overview & Core Advantages
The 680ZZ is a metric miniature ball bearing designed for applications demanding compact size and reliable performance. As a single row deep groove ball bearing, it excels at handling radial loads and is constructed entirely from stainless steel for enhanced corrosion resistance. Its shielded (ZZ) design offers effective protection against contaminant ingress, making it a robust and durable choice for high-speed, precision applications where space is at a premium.
SF695zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 680 | The bearing series number, indicating a miniature bearing with a 5mm bore, 13mm outside diameter, and 4mm width. |
| ZZ | Denotes shielded on both sides. The non-contact shields protect the internal components from dust and debris while minimizing friction. |
SF695zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of just 5x13x4 mm and a weight of 2.65 g, this bearing is ideal for applications with severe space and weight constraints.
- Corrosion Resistance: Manufactured from 300 series stainless steel for the rings, balls, cage, and shields, it offers excellent performance in corrosive or wash-down environments.
- High-Speed Capability: The deep groove raceway and stainless steel cage contribute to a high limiting speed of 38,700 rpm, suitable for demanding miniature machinery.
- Precision Performance: Manufactured to ABEC1 tolerance class, ensuring consistent running accuracy and smooth operation.
- Shielded Protection: The ZZ shields help retain lubrication and exclude contaminants, extending bearing service life without the added friction of contact seals.
SF695zz Bearing Typical Application Areas
- Small precision electric motors and miniature gear motors
- Medical and dental hand tools
- Optical encoders and precision instruments
- Small fans and blowers
- Radio-controlled models (RC cars, drones)
- Office automation equipment (printers, scanners)
- Textile machinery guides and tensioners
