F679 Bearing Product Overview & Core Advantages
The F679 is a metric single row deep groove ball bearing engineered for high performance in compact spaces. Its primary design focus is providing reliable radial load support in applications demanding a minimal cross-section. Manufactured from chrome steel with a stainless steel cage, it offers excellent durability and corrosion resistance. The bearing's open design allows for versatile lubrication options, making it suitable for a wide operational temperature range from -30°C to 110°C. Its compact dimensions (9mm bore, 14mm OD, 3mm width) and low weight (1.57g) make it an ideal choice for precision mechanisms where space and weight are critical constraints.
F679 Bearing Model Code Explained, Specifications & Naming Convention
- F679: Basic model number indicating a specific bearing series with a 9mm bore diameter.
- Open Seal Type: No sealing, indicated by the absence of a seal suffix (e.g., -2RS). This allows for high-speed operation and custom lubrication.
- ABEC1 Tolerance Class: Denotes a standard level of precision for runout and dimensional accuracy.
- MC3 Radial Clearance: Specifies a standard radial internal clearance group (0.002mm to 0.013mm) for general operating conditions.
F679 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The stainless steel cage and open design contribute to a high limiting speed of 36,000 rpm, making it a capable high-speed bearing for its size.
- Radial Load Capacity: The single row deep groove construction is optimized to handle significant radial dynamic load ratings (176 lbf) and radial static load ratings (84 lbf).
- Compact & Lightweight Design: With a width of just 3mm and a weight of 1.57g, it provides a high load capacity in an extremely small envelope, enabling miniaturization in design.
- Material Integrity: The use of chrome steel for rings and balls ensures high hardness and wear resistance, while the stainless steel cage offers enhanced durability.
F679 Bearing Typical Application Areas
- Small Precision Electric Motors (e.g., drone motors, miniature fans)
- Office Automation Equipment (printers, scanners)
- Medical and Dental Handpieces
