SF6806ZZ Bearing Product Overview & Core Advantages
The SF6806ZZ is a metric flanged ball bearing engineered for precision and reliability in compact spaces. As a single row, shielded bearing, it is specifically designed to handle radial loads efficiently. Its flanged design enhances mounting stability and simplifies axial location in housings. Manufactured with stainless steel rings and cage and chrome steel balls, it offers excellent corrosion resistance and durability. With an ABEC-1 precision class and pre-lubrication requirement, it is ideal for applications demanding consistent performance, high limiting speed (13,500 rpm), and long service life in varied temperature conditions.
SF6806ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning | Benefit / Characteristic |
|---|---|---|
| SF | Flanged Ball Bearing Series Designation | Identifies the bearing as part of a flanged series for easy mounting and positioning. |
| 68 | Bore Diameter Code (30 mm) | Specifies the 30 mm bore diameter. |
| 06 | Outside Diameter Series Code | Indicates the specific outside diameter (42 mm) and cross-section. |
| ZZ | Shielded on Both Sides | Provides effective protection against contaminants while retaining lubricant, contributing to low maintenance requirements. |
SF6806ZZ Bearing Structural Features & Performance Benefits
Flanged Outer Ring: The integrated flange (45 mm outer diameter, 1.5 mm thickness) provides positive locating and secure mounting, reducing the need for complex housing designs and improving assembly accuracy.
Single Row Deep Groove Raceway: Optimized for high radial load capacity (Dynamic: 900 lbf, Static: 696 lbf), ensuring reliable performance under primary radial forces.
Stainless Steel Construction: The rings and cage are made from stainless steel, offering superior corrosion resistance, making the bearing suitable for harsh environments and washdown applications.
Shielded Design (ZZ): The non-contact steel shields on both sides effectively exclude larger particulate contaminants and retain lubricant, enhancing bearing life and enabling operation at the high limiting speed of 13,500 rpm.
Precision & Clearance: Built to ABEC-1 tolerance standards with a C0 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and quiet operation with minimal runout.
SF6806ZZ Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in small DC motors, stepper motors, and servo motors.
- Office Automation Equipment: Used in printers, scanners, and copiers for precise roller and shaft guidance.
- Medical Devices: Suitable for low-noise, corrosion-resistant applications in diagnostic equipment and small pumps.
- Food Processing & Packaging Machinery: The stainless steel construction meets hygiene standards for components in conveyors and fillers.
- Instrumentation and Control Systems: Provides reliable rotation in encoders, sensors, and other precision measurement devices.
