Structural Features & Performance Advantages
Flanged Design: The integrated flange (40mm outer diameter, 2mm thickness) provides precise axial location and simplifies housing design, reducing assembly complexity and cost.
Deep Groove Geometry: Optimized raceway design enables excellent radial load capacity (871 lbf dynamic, 593 lbf static) while accommodating moderate axial loads in both directions.
Stainless Steel Construction: All components including rings, cage, and shields utilize stainless steel materials, ensuring superior corrosion resistance and suitability for harsh environments.
Double Shield Protection: The ZZ shields effectively retain lubrication and exclude contaminants, contributing to maintenance-free operation in many applications.
Precision Engineering: With ABEC-1 tolerance class and C0 radial clearance (0.002-0.013mm), this bearing delivers consistent performance and smooth running characteristics.
SF63805ZZ Bearing Typical Application Areas
- Medical Equipment: Surgical instruments, dental handpieces, and diagnostic devices requiring corrosion resistance
