618/1180 MB Bearing Product Overview & Core Advantages
The 618/1180 MB is a single row deep groove ball bearing engineered for demanding industrial applications requiring exceptional radial load capacity and precision operation. This metric series bearing features a large 1180 mm bore and is manufactured to P6 tolerance class, ensuring high running accuracy and dimensional stability. Its robust construction, utilizing chrome steel rings and balls with a stainless steel cage, delivers reliable performance and long service life. The open design allows for versatile lubrication options, making it suitable for systems with centralized lubrication.
618/1180 MB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 618 | Series designation for extra large, single row deep groove ball bearings. | Indicates the bearing's cross-sectional design and size series. |
| 1180 | Bore diameter in millimeters (mm). | Specifies the 1180 mm inner diameter for shaft mounting. |
| MB | Designates a brass cage with machined pockets. | The machined brass cage provides high strength, excellent guidance, and suitability for high-vibration applications. |
618/1180 MB Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The deep groove raceway and optimized internal geometry enable it to support substantial radial dynamic load ratings of 171,080 lbf and radial static load ratings of 530,549 lbf, making it ideal for heavy-duty machinery.
- Precision Performance: Manufactured to P6 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth, precise rotation and minimizes vibration in precision applications.
- Robust Cage Design: The machined brass (MB) cage offers superior strength and stability compared to stamped cages, providing reliable performance under high speeds and strenuous conditions.
- Material Integrity: Components made from chrome steel (rings and balls) provide high hardness and wear resistance, while the stainless steel cage enhances corrosion resistance in certain environments.
- Versatile Lubrication: The open seal type allows for easy initial lubrication and is compatible with various grease or oil systems, adaptable to specific operational requirements.
