F6904ZZ Bearing Structural Features & Performance Benefits
- Flanged Design: The integrated flange on the outer ring provides precise axial location and simplifies housing design, reducing assembly time and cost.
- Shielded Protection: The 300 Series Stainless Steel shields (ZZ) effectively retain lubricant and exclude larger contaminants, enhancing bearing life in dirty environments.
- High-Speed Capability: Featuring a stainless steel cage and optimized internal geometry, this bearing supports a limiting speed of 19,000 rpm, making it ideal for high-speed applications.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance, it ensures smooth and quiet operation with consistent running accuracy.
- Robust Construction: Components made from chrome steel (rings and balls) provide high load capacity, with a dynamic load rating of 1434 lbf and static load rating of 827 lbf.
F6904ZZ Bearing Typical Application Areas
- Small Precision Motors (e.g., drone motors, RC vehicles)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical Devices (e.g., dental handpieces, small pumps)
