6011-2Z/C3VT127 Bearing Product Overview & Core Advantages
The 6011-2Z/C3VT127 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This precision bearing features integral shields (2Z) for contaminant protection and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable and consistent operation. Its key advantage lies in its ability to handle significant radial loads while offering a generous C3 radial internal clearance, making it exceptionally suitable for applications involving thermal expansion or where shaft misalignment is a concern. The combination of robust construction and optimized internal geometry results in a compact, high-performance component ideal for high-reliability scenarios.
6011-2Z/C3VT127 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6011 | Standard bearing series designation, indicating a metric deep groove ball bearing with a 55mm bore, 90mm OD, and 18mm width. | Defines the core bearing dimensions and basic type. |
| 2Z | Bearing is equipped with shields on both sides. | Provides effective protection against solid contaminants, retaining lubrication and extending service life. Offers a good balance between sealing and limiting speed. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion of the shaft and housing, or slight misalignments, preventing premature failure due to excessive preload. |
| VT127 | Manufacturer-specific suffix, often indicating special material treatment or process control. | Denotes enhanced manufacturing quality and consistency, contributing to overall bearing reliability. |
6011-2Z/C3VT127 Bearing Structural Features & Performance Benefits
The 6011-2Z/C3VT127's performance is derived from its specific design and material selection:
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high radial dynamic load rating of 6362 lbf and a radial static load rating of 4766 lbf, ensuring durability under substantial loads.
- Optimized Internal Geometry (C3 Clearance): The specified C3 internal clearance is critical for applications prone to thermal expansion, such as in electric motors or gearboxes. This prevents binding and reduces friction, contributing to stable operation and extended service life.
- Controlled Friction & High-Speed Capability: The deep groove raceway and precision-ground components minimize friction and vibration. Combined with the steel cage, this allows for a high limiting speed of 7,500 rpm, making it a capable high-speed bearing for many industrial applications.
- Low-Maintenance Operation: The integral shields (2Z) effectively protect the bearing's interior from dust and debris, retaining any subsequently applied lubricant. This design significantly reduces maintenance frequency and the risk of contamination-related failures.
6011-2Z/C3VT127 Bearing Typical Application Areas
This versatile and robust bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Systems (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
- General Industrial Machinery requiring reliable radial load support
