SF6906ZZ Bearing Structural Features & Performance Benefits
- Flanged Design: The integrated flange (outer diameter: 50 mm, thickness: 2 mm) ensures easy installation and precise axial positioning, reducing the need for complex housing designs.
- Shielded Protection: Both sides are sealed with 300 series stainless steel shields, offering robust defense against dust and debris while maintaining low friction.
- High-Quality Materials: The combination of stainless steel rings and cage with chrome steel balls provides excellent corrosion resistance and high load capacity, supporting a radial dynamic load rating of 1465 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance with a radial internal clearance of C0 (0.002mm to 0.013mm), ensuring smooth operation and reduced vibration.
- Optimized Performance: With 14 balls of 4.762 mm diameter and a limiting speed of 12,600 rpm, it delivers reliable performance in high-speed applications.
SF6906ZZ Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle and rotor support in compact motors due to its flanged design and high-speed capability.
- Precision Instruments: Used in optical devices, measuring equipment, and laboratory instruments where accurate rotation and minimal runout are critical.
- Office Automation Equipment: Commonly found in printers, scanners, and copiers for reliable radial load support and contamination resistance.
- Medical Devices: Suitable for low-to-moderate load applications in medical machinery, benefiting from its stainless steel construction and shielded design.
- Robotics and Automation: Applied in small robotic joints and linear guides where compact dimensions and precise movement are essential.
