SF6805ZZ Bearing Product Overview & Core Advantages
The SF6805ZZ is a metric flanged ball bearing engineered for compact applications requiring reliable radial load support and precise positioning. This single row bearing features integral stainless steel shields (ZZ) for contaminant protection and is constructed from corrosion-resistant materials, making it suitable for demanding environments. Its primary advantages include a high limiting speed of 16,200 rpm, a robust radial dynamic load rating of 870 lbf, and a lightweight, space-saving flanged design that simplifies mounting and enhances positional stability in assemblies.
SF6805ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF6805 | Basic bearing designation indicating a flanged design with a 25 mm bore diameter, 37 mm outside diameter, and 7 mm width. |
| ZZ | Signifies shielded on both sides. The shields are made from 300 Series Stainless Steel, providing effective protection against contaminants while allowing for high-speed operation. |
SF6805ZZ Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of 15 precision chrome steel balls and a stainless steel cage ensures stable operation at the high limiting speed of 16,200 rpm, making it an excellent high-speed bearing choice.
- Robust Load Capacity: With a radial dynamic load rating of 870 lbf and a radial static load rating of 595 lbf, it reliably handles significant radial loads in compact spaces.
- Enhanced Mounting & Stability: The integral flange (40 mm outer diameter) provides secure axial location, simplifies assembly, and increases resistance to mounting misalignment.
- Corrosion Resistance & Durability: Constructed with stainless steel rings and cage, this bearing offers superior corrosion resistance, ideal for applications exposed to moisture or harsh chemicals.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a standard C0 radial internal clearance, it delivers consistent and smooth running for general precision applications.
SF6805ZZ Bearing Typical Application Areas
- Small Electric Motors and Spindles in power tools, drones, and robotics.
- Precision Instruments and Medical Devices requiring compact, reliable rotary motion.
- Office Automation Equipment such as printers, scanners, and copiers.
- Food Processing & Packaging Machinery where corrosion resistance is critical.
- Automotive Auxiliary Systems including idler pulleys, actuators, and small pumps.
