SF6906 Bearing Product Overview & Core Advantages
The SF6906 is a flanged ball bearing designed for compact applications requiring reliable radial load support. Its single row construction and open seal design make it ideal for precision assemblies where space is limited. Manufactured with stainless steel rings and chrome steel balls, this bearing offers excellent corrosion resistance and durability. With an ABEC-1 tolerance class and C0 radial clearance, it provides consistent performance in general-purpose industrial applications.
SF6906 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF6906 | Basic model designation for flanged ball bearing series |
| Open | No seals or shields, allowing for direct lubrication access |
| ABEC-1 | Standard precision class for general industrial applications |
| C0 | Normal radial internal clearance range (0.002mm to 0.013mm) |
SF6906 Bearing Structural Features & Performance Benefits
Flanged Design: The integrated flange (50mm outer diameter, 2mm thickness) provides secure mounting and precise positioning, eliminating the need for additional housing components and reducing assembly complexity.
Material Composition: Stainless steel rings and 300 series stainless steel shield material ensure excellent corrosion resistance, while chrome steel balls deliver optimal hardness and wear resistance for extended service life.
Load Capacity: With a radial dynamic load rating of 1465 lbf and static load rating of 1014 lbf, this bearing reliably handles moderate radial loads in various operating conditions.
Precision Engineering: The 14 chrome steel balls (4.762mm diameter) combined with stainless steel cage provide smooth operation and maintain ball bearing alignment at limiting speeds up to 12,600 rpm.
