F625 2rs Bearing Product Overview & Core Advantages
The F625 2rs is a metric miniature ball bearing designed for compact applications requiring reliable performance. As a single row deep groove ball bearing with integral rubber seals (2RS), it provides effective protection against contamination while retaining lubrication. This bearing is engineered to primarily handle radial loads and is characterized by its small bore diameter of 5 mm and lightweight construction. It is an ideal component for applications demanding compact design, moderate speed capability, and dependable operation in various industrial environments.
F625 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| F625 | Basic bearing designation indicating a metric, single row deep groove bearing with a 5mm bore and 16mm outside diameter. | Defines the core bearing dimensions and type. |
| 2RS | Contact Nitrile Rubber Seals on both sides of the bearing. | Provides superior contamination exclusion and grease retention, enhancing bearing life and enabling maintenance-free operation in many applications. |
F625 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high radial load capacity relative to its miniature size. The geometry ensures smooth operation and low running torque.
- Integrated Rubber Seals (2RS): The Nitrile rubber seals make direct contact with the inner ring, effectively shielding the 7 high-precision chrome steel balls and stainless steel cage from dust, moisture, and other contaminants. This design significantly extends service life and reliability.
- Precision Construction: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), ensuring consistent performance, low noise, and vibration.
- High-Speed Capability: The lightweight stainless steel cage and optimized internal geometry contribute to a high limiting speed of 36,000 rpm, making it suitable for demanding high-speed applications.
- Robust Material Selection: Rings and balls made from chrome steel provide high load ratings and durability, while the stainless steel cage offers excellent corrosion resistance.
F625 2rs Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle support in miniature DC motors, stepper motors, and fans.
- Precision Instruments & Medical Devices: Used in optical encoders, small gauges, and handheld medical tools where compact size and reliability are critical.
- Office Automation Equipment: Commonly found in printers, scanners, and copiers for paper feed rollers and scanner heads.
- Radio-Controlled Models & Drones: Provides smooth, efficient performance in motor and gearbox assemblies.
- Small Power Tools & Appliances: Suitable for the internal mechanisms of compact drills, trimmers, and kitchen appliances.
