SF6902 Bearing Product Overview & Core Advantages
The SF6902 is a metric flanged ball bearing engineered for precision radial load applications requiring compact design and reliable performance. This single row bearing features a stainless steel construction that provides excellent corrosion resistance, making it suitable for demanding environments. Its integrated flange ensures secure mounting and precise positioning while maintaining a minimal footprint. With an ABEC-1 tolerance class, this bearing delivers consistent operation for applications where space constraints and reliability are critical factors.
SF6902 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SF6902 | Basic bearing designation with flanged design | Compact radial space solution with mounting stability |
| Open | No seal/shield (open construction) | Allows for custom lubrication solutions and maximum speed capability |
| Stainless Steel | 300 series stainless steel rings and cage | Superior corrosion resistance and durability in harsh environments |
SF6902 Bearing Structural Features & Performance Benefits
Flanged Design Advantage: The integrated flange (30mm outer diameter) provides secure mounting and precise axial positioning, eliminating the need for additional housing components and reducing assembly complexity.
Material Excellence: Constructed with stainless steel rings and cage combined with chrome steel balls, this bearing offers optimal corrosion resistance while maintaining excellent mechanical properties. The material combination ensures reliable performance across the operating temperature range of -30° to 110°C.
Precision Engineering: With ABEC-1 tolerance and C0 radial internal clearance (0.002mm to 0.013mm), the SF6902 delivers consistent running accuracy and smooth operation. The optimized ball complement (10 balls of 3.969mm diameter) provides excellent load distribution and rotational characteristics.
Performance Capabilities: The bearing achieves a limiting speed of 21,600 rpm and handles radial dynamic loads up to 876 lbf (3897 N), making it suitable for high-speed applications requiring reliable radial load support.
