F634zz Bearing Structural Features & Performance Benefits
- Compact Flange Design: The integrated flange (18mm OD, 1mm thickness) enables secure mounting and axial positioning, simplifying assembly in confined spaces.
- Optimized Load Capacity: With a radial dynamic load rating of 256 lbf and static load rating of 94 lbf, it handles substantial radial loads despite its miniature bearing dimensions (4mm bore × 16mm OD × 5mm width).
- High-Speed Capability: The stainless steel cage and 7 precision chrome steel balls (2.381mm diameter) ensure stable operation at limiting speeds of 36,000 rpm.
- Controlled Internal Clearance: MC3 radial clearance (0.002mm to 0.013mm) provides optimal running accuracy and low noise in precision mechanisms.
- Material Durability: Chrome steel rings and stainless steel components offer excellent wear resistance and corrosion protection.
F634zz Bearing Typical Application Areas
- Small DC Motors and stepper motors in automation equipment
- Precision Instrumentation including optical encoders and medical devices
- Office Machinery such as printers, scanners, and copiers
