602zz Bearing Product Overview & Core Advantages
The 602zz is a single row deep groove ball bearing, a fundamental and versatile component in precision mechanical systems. Engineered as a shielded bearing, it offers reliable protection against contamination while being optimized for high-speed operation. Its compact design, with a minimal cross-section, makes it an ideal choice for applications where space is at a premium. This bearing is designed to primarily support radial loads and is characterized by its low friction and smooth running capabilities, ensuring high operational efficiency and long service life in demanding environments.
602zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 60 | Bearing Series | Indicates a deep groove ball bearing with a specific dimension series. |
| 2 | Bore Diameter Code | Signifies a 2 mm bore diameter. |
| zz | Shield Configuration | Denotes shields on both sides. This provides effective protection from particulate contaminants, retaining lubrication and enhancing bearing longevity. |
602zz Bearing Structural Features & Performance Benefits
- Robust Construction & High-Speed Capability: Manufactured from chrome steel for both rings and balls, the bearing offers high hardness and wear resistance. The stainless steel cage ensures stability and guides the balls effectively at the limiting speed of 60,000 rpm.
- Optimized Internal Geometry: The deep groove raceway and the use of seven precision balls enable efficient handling of radial loads (dynamic: 74 lbf, static: 23 lbf). The MC3 radial internal clearance (0.002mm to 0.013mm) is suited for applications requiring precise running accuracy.
- Enhanced Reliability with Shields: The 300 series stainless steel shields protect the internal components from dust and debris, making the bearing highly reliable in unclean environments. This design helps retain lubricant, contributing to a maintenance-free operation for a significant portion of its service life.
- Precision and Compliance: Built to ABEC1 tolerance class, this bearing provides consistent and reliable performance for general precision applications. It is also ROHS and REACH compliant, meeting stringent environmental regulations.
602zz Bearing Typical Application Areas
This miniature bearing is widely used in compact and high-speed devices, including:
- Small Electric Motors (e.g., in drones, RC models, and small fans)
- Precision Instruments and optical encoders
- Office Automation Equipment such as printers and scanners
- Medical Devices and dental handpieces
- Computer Hard Disk Drives and cooling fans
