626-2Z/C3HVK215 Bearing Product Overview & Core Advantages
The 626-2Z/C3HVK215 is a metric single row deep groove ball bearing designed for robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering reliable operation. The bearing features integrated shields (2Z) for contaminant protection and a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Constructed entirely from chrome steel, it provides excellent durability and is engineered for high reliability in a compact form factor.
626-2Z/C3HVK215 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 626 | Basic bearing series | Denotes a standard metric, single row deep groove ball bearing with a 6mm bore. |
| 2Z | Shielded on both sides | Provides effective protection against contamination while allowing for high-speed operation. It is a non-contact seal, minimizing friction. |
| C3 | Radial internal clearance greater than Normal (C0) | Accommodates thermal expansion in the shaft or housing, or is used for applications with heavy interference fits, preventing premature failure. |
| HVK215 | Manufacturer's internal designation | May refer to specific manufacturing process, material batch, or other proprietary specifications. |
626-2Z/C3HVK215 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling significant radial loads. The deep groove geometry also allows it to accommodate moderate axial loads in both directions.
- Shielded Construction (2Z): The steel shields protect the internal components from dust and other particulates, enhancing bearing life and reliability without the added friction of contact seals. This contributes to the bearing's high limiting speed of 32,000 rpm.
- Chrome Steel Construction: All core components—rings, balls, and cage—are made from chrome steel, ensuring high hardness, wear resistance, and long-term performance.
- C3 Radial Clearance: This greater-than-normal clearance is critical for applications where thermal expansion is a factor or where press fits are used, preventing operational issues caused by excessive preload.
- ABEC 1 / ISO P0 Precision: Manufactured to standard precision grades, ensuring consistent performance and reliable operation for a wide range of industrial uses.
626-2Z/C3HVK215 Bearing Typical Application Areas
The 626-2Z/C3HVK215 is versatile and finds use in various compact and high-speed machinery, including:
- Small Electric Motors and Gearboxes
- Precision Instruments and Medical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
