SF679 Bearing Product Overview & Core Advantages
The SF679 is a miniature deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. This metric single row bearing features an open design and is constructed entirely from stainless steel, providing excellent corrosion resistance. Its primary advantages include a high limiting speed of 32,400 rpm and the ability to handle radial loads efficiently, making it ideal for precision instruments and small machinery where space is constrained and operational reliability is critical.
SF679 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF679 | Basic bearing designation indicating specific dimensions (9mm bore, 14mm OD, 3mm width) |
| Open | No seals or shields, allowing for higher speeds and custom lubrication |
| ABEC1 | Standard precision class suitable for most industrial applications |
| MC3 | Radial internal clearance group (0.002mm to 0.013mm) for general operating conditions |
SF679 Bearing Structural Features & Performance Benefits
All-Stainless Steel Construction: Both rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and medical applications.
High-Speed Capability: The open design, combined with 12 precision balls and stainless steel cage, enables operation at limiting speeds up to 32,400 rpm, making it an excellent choice for high-speed miniature applications.
Precision Engineering: Manufactured to ABEC1 tolerance standards with controlled radial internal clearance (MC3 group), ensuring consistent performance and smooth operation.
Compact & Lightweight: With dimensions of 9mm bore × 14mm OD × 3mm width and weighing only 1.57g, this bearing offers space-saving solutions without compromising radial load capacity (158 lbf dynamic rating).
