618/1700 MB Bearing Product Overview & Core Advantages
The 618/1700 MB is a single row deep groove ball bearing engineered for applications requiring exceptional radial load capacity and precision operation. This metric series bearing features an open design, facilitating direct lubrication and optimal heat dissipation. Its core advantages include an extremely high radial static load rating of 1,101,564 lbf, making it suitable for supporting substantial weights in low-speed, high-load environments. Manufactured to a P6 tolerance class, it ensures precise running accuracy and reliable performance in demanding industrial settings.
618/1700 MB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 618 | Series designation for extra small cross-section, deep groove ball bearings. |
| 1700 | Nominal bore diameter in millimeters (1700 mm). |
| MB | Designates a brass cage (Note: Specification lists Stainless Steel cage, "MB" is a common designation for brass; please verify cage material for specific application). |
618/1700 MB Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and robust construction are optimized to handle the massive radial dynamic load rating of 285,507 lbf and an exceptional radial static load rating, providing stable support in heavy-duty applications.
- Precision Engineering: Conforming to P6 tolerance class and standard CN radial internal clearance, this bearing ensures smooth, precise rotation and minimizes vibration, contributing to the longevity of the entire assembly.
- Durable Material Construction: Rings and balls made from Chrome Steel offer high wear resistance and durability. The specified Stainless Steel cage provides excellent corrosion resistance and strength.
- Open Seal Design: The open (unsealed) configuration allows for custom lubrication schemes, ideal for applications where the bearing is integrated into a central lubrication system.
618/1700 MB Bearing Typical Application Areas
This large-bore 618/1700 MB bearing is typically employed in heavy machinery and large-scale industrial equipment, including:
- Large-Diameter Rotating Machinery
- Industrial Turntables and Slewing Rings
- Heavy-Duty Support Rollers in mining and material handling
- Wind Turbine Main Shafts (as a component in larger assemblies)
- Large Precision Instruments and test rigs requiring high static load capacity
