602xzz Bearing Product Overview & Core Advantages
The 602xzz is a metric miniature ball bearing engineered for high precision and reliability in compact applications. As a single row radial ball bearing, it is designed to primarily support radial loads while offering a low-friction, high-speed solution. Its shielded construction provides effective protection against contamination, making it an ideal choice for applications demanding long service life and minimal maintenance. This bearing is characterized by its small bore diameter of 2.5 mm and compact cross-section, delivering robust performance in a minimal footprint.
602xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 60 | Series designation, indicating a deep groove ball bearing with a specific cross-section. |
| 2 | Bore diameter code. In this case, it corresponds to a 2.5 mm bore. |
| ZZ | Denotes shielded on both sides. The shields protect the internal components from dust and debris while allowing for high-speed operation. |
602xzz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and optimized internal geometry enables a high limiting speed of 60,000 rpm.
- Radial Load Capacity: With a dynamic load rating of 106 lbf and a static load rating of 32 lbf, this bearing provides reliable support for significant radial forces relative to its size.
- Contamination Protection: The 300 Series Stainless Steel shields (ZZ) effectively retain lubrication and exclude large particulate contaminants, enhancing bearing life and reliability.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 / 0.002mm to 0.013mm), ensuring smooth and consistent operation with minimal runout.
- Durable Material Construction: Rings and balls made from chrome steel provide high hardness and wear resistance, while the stainless steel cage offers excellent corrosion resistance and strength.
602xzz Bearing Typical Application Areas
This miniature shielded ball bearing is ideally suited for a wide range of compact and high-speed devices, including:
- Small Precision Motors (e.g., drones, RC models, small fans)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Instrumentation and Measurement Devices
- Computer Disk Drives and other data storage equipment
