F689 Bearing Product Overview & Core Advantages
The F689 is a metric single row deep groove ball bearing engineered for compact applications requiring reliable performance. Characterized by its open design and standard ABEC1 precision class, this bearing is optimized for high-speed operation up to 36,000 rpm. Its primary function is to support radial loads efficiently, making it an ideal component for space-constrained assemblies where a balance of performance, size, and cost is critical. The bearing is constructed from high-grade chrome steel for durability and features a stainless steel cage for stability at high rotational speeds.
Model Code Breakdown
| Model Segment | Technical Meaning |
|---|---|
| F689 | Standard model designation for a single row deep groove ball bearing with a 9mm bore. |
| Open | No seals or shields, allowing for higher speed capability and requiring external lubrication. |
| MC3 | Specifies the radial internal clearance group (0.002mm to 0.013mm), suitable for applications with moderate operational temperatures and fits. |
F689 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of an open design and a lightweight, durable stainless steel cage minimizes friction and allows for a high limiting speed of 36,000 rpm, making it a true high-speed bearing.
- Robust Load Capacity: The single row deep groove construction is designed to support significant radial loads (dynamic: 254 lbf, static: 120 lbf), providing reliable performance under stress.
- Precision & Stability: Manufactured to ABEC1 tolerance class with tight dimensional control on the bore diameter (9mm) and outside diameter (17mm), ensuring consistent and accurate operation.
- Compact & Lightweight: With a minimal width of just 4mm and a low weight of 3.85g, it is an excellent choice for miniaturized and weight-sensitive applications.
F689 Bearing Typical Application Areas
- Small Electric Motors and Spindles
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., printers, scanners)
- Radio-Controlled Models and Drones
- Medical Devices and Dental Handpieces
- Computer Cooling Fans
