SF6801ZZ Bearing Product Overview & Core Advantages
The SF6801ZZ is a flanged miniature ball bearing designed for compact applications requiring precise positioning and space optimization. This single row deep groove ball bearing features integral shielding and is constructed from corrosion-resistant materials, making it ideal for applications demanding high reliability and long service life. Its flanged design facilitates easier mounting and provides axial location, while the shielded construction offers protection against contamination. Engineered to handle primarily radial loads, this bearing is a cornerstone component in precision mechanical systems.
SF6801ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF | Flanged bearing series designation. |
| 68 | Indicates a specific miniature bearing series with a 5mm width. |
| 01 | Specifies a 12mm bore diameter. |
| ZZ | Signifies the bearing is equipped with non-contact shields on both sides. This provides effective protection against dust and other particulates while minimizing friction. |
SF6801ZZ Bearing Structural Features & Performance Benefits
- Flanged Design for Simplified Assembly: The outer ring flange (Ø23mm) allows for straightforward mounting into a housing, providing secure axial location and simplifying the overall assembly process, which is critical for miniature bearing applications.
- Robust Shielding: The 300 Series Stainless Steel shields (ZZ) protect the internal rolling elements from contaminants, enhancing bearing life and reliability in challenging environments without significantly increasing rotational torque.
- Corrosion-Resistant Construction: Manufactured with stainless steel rings and cage, this bearing offers excellent resistance to rust and corrosion, suitable for applications exposed to moisture or mild chemicals.
- Precision Performance: Built to ABEC-1 tolerance class with a standard C0 radial internal clearance, it ensures smooth and consistent operation, making it a reliable precision bearing for various mechanisms.
- High-Speed Capability: With a limiting speed of 27,000 rpm, it is well-suited for high-speed miniature applications such as small motors and precision spindles.
SF6801ZZ Bearing Typical Application Areas
- Small Precision Motors (e.g., drone motors, RC vehicles)
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and Instrumentation
- Computer Peripheral Equipment (hard disk drives, cooling fans)
- Textile Machinery Guides and Tensioners
- Precision Gearboxes and Small Robotic Joints
