SF6702ZZ Bearing Structural Features & Performance Benefits
Compact Flange Design: The integrated flange (22.5mm OD, 0.8mm thickness) enables secure mounting and precise axial positioning, reducing assembly complexity and improving structural integrity.
High-Quality Materials: Constructed with stainless steel rings and cage combined with chrome steel balls, providing excellent corrosion resistance and durability in harsh environments.
Optimized Internal Geometry: Features 14 precision balls (1.588mm diameter) arranged in a single row configuration, ensuring smooth rotation and high radial load capacity (190 lbf dynamic, 118 lbf static).
Enhanced Contamination Protection: Double stainless steel shields (ZZ) effectively retain lubrication and exclude contaminants, extending service life in demanding applications.
Precision Performance: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (C0: 0.002-0.013mm), ensuring consistent operation and minimal vibration.
