F624zz Bearing Product Overview & Core Advantages
The F624zz is a metric miniature ball bearing engineered for precision applications requiring compact design and reliable performance. As a single row deep groove ball bearing, it is optimized to handle primarily radial loads efficiently. Its shielded (ZZ) construction provides effective contamination protection, making it a robust choice for high-speed operations and applications demanding long-term reliability with minimal maintenance. This bearing is characterized by its small bore diameter of 4 mm and lightweight design, weighing only 3.54 g, making it ideal for space-constrained assemblies.
F624zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F624 | Indicates the bearing series and size. The '6' often denotes a deep groove design with specific dimensions: 4mm bore, 13mm OD, 5mm width. |
| zz | Signifies that the bearing is equipped with shields on both sides. This provides protection against solid contaminants while allowing for high-speed operation. |
F624zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage and precision-ground chrome steel components enables a limiting speed of 40,000 rpm, making it an excellent high-speed bearing.
- Radial Load Capacity: The deep groove raceway and optimized ball complement (7 balls of 2.381 mm diameter) provide a dynamic load rating of 249 lbf and a static load rating of 88 lbf for reliable performance under stress.
- Contamination Resistance: The 300 series stainless steel shields (ZZ) protect the internal components from dust and debris, extending bearing life and reducing maintenance needs.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring smooth and consistent operation.
- Material Durability: Constructed from chrome steel rings and balls with a stainless steel cage, offering excellent resistance to wear and corrosion.
F624zz Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle and rotor support in miniature DC motors and stepper motors.
- Office Automation Equipment: Used in printers, scanners, and copiers for paper feed rollers and scanner carriages.
- Medical Devices: Suitable for small pumps, dental handpieces, and laboratory instrumentation requiring quiet, precise rotation.
- Robotics and Automation: Applied in small robotic joints, conveyor system rollers, and precision guidance systems.
- Consumer Electronics: Found in computer cooling fans, small drones, and various portable electronic devices.
