SF6802ZZ Bearing Product Overview & Core Advantages
The SF6802ZZ is a metric miniature flanged ball bearing designed for precision applications requiring compact design and reliable performance. This single row deep groove ball bearing features shielded construction for contaminant protection while maintaining excellent radial load capacity. Manufactured with stainless steel rings and cage, it offers superior corrosion resistance and durability. The integrated flange provides secure mounting and precise positioning in compact assemblies, making it ideal for applications where space constraints and high rotational accuracy are critical requirements.
Model Code Detailed Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SF6802 | Basic bearing designation with 15mm bore, 24mm OD, 5mm width | Compact metric dimensions for space-constrained applications |
| ZZ | Double shielded (both sides) | Enhanced contaminant protection, reduced maintenance requirements |
SF6802ZZ Bearing Structural Features & Performance Benefits
Flanged Design: The integrated flange (26mm OD, 1.1mm thickness) enables precise axial positioning and simplifies mounting in housing structures, reducing assembly complexity and improving alignment accuracy.
Shielded Protection: Double stainless steel shields (300 series) provide effective contaminant exclusion while maintaining low friction operation, extending bearing service life in demanding environments.
Precision Engineering: Manufactured to ABEC-1 tolerance class with C0 radial clearance (0.002-0.013mm), ensuring consistent performance and smooth operation across the temperature range of -30° to 110°C.
Optimized Load Capacity: With a dynamic radial load rating of 419 lbf and static radial load rating of 255 lbf, the bearing delivers reliable performance under substantial radial loads while maintaining a limiting speed of 23,400 rpm.
Material Excellence: Stainless steel construction throughout (rings, cage, shields) combined with chrome steel balls provides excellent corrosion resistance and mechanical strength for long-term reliability.
