619/800 MA Bearing Product Overview & Core Advantages
The 619/800 MA is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric series bearing features an open design and is manufactured to a P6 tolerance class, ensuring high precision and reliable operation. Its primary advantage lies in its robust construction, capable of supporting high radial loads, making it an ideal choice for heavy-duty machinery where precision and durability are paramount. The large bore diameter of 800 mm allows it to be fitted on substantial shafts, providing a compact and highly effective solution for power transmission systems.
619/800 MA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 619 | Series designation for deep groove ball bearings with a large bore and low cross-section. |
| 800 | Nominal bore diameter in millimeters (800 mm). |
| MA | Indicates a brass cage (machined). This cage offers high strength and stability, suitable for high-speed applications and demanding conditions. |
619/800 MA Bearing Structural Features & Performance Benefits
- High Load Capacity: Built from chrome steel rings and balls, this bearing delivers a high radial dynamic load rating of 187,041 lbf and an exceptional radial static load rating of 458,610 lbf, enabling it to withstand significant forces in heavy machinery.
- Precision & Stability: Manufactured to P6 tolerance with a standard CN radial internal clearance, it ensures smooth, precise rotation and minimal vibration, which is critical for maintaining operational accuracy.
- Robust Cage Design: The machined brass (MA) cage provides superior guidance for the balls, enhancing operational stability and making the bearing suitable for a limiting speed of 800 rpm despite its large size.
- Versatile Operating Conditions: With a wide operating temperature range from -30°C to 120°C and no pre-applied lubrication (lubrication: None), it offers flexibility for various industrial environments, allowing for the use of specialized greases as required by the application.
619/800 MA Bearing Typical Application Areas
This bearing is designed for large-scale, heavy-duty industrial equipment. Common applications include:
- Large Industrial Gearboxes and power transmission systems.
- Heavy-Duty Mining and Construction Machinery, such as crushers and large conveyor pulleys.
- Vibrating Screens and other processing equipment requiring high radial load capacity.
- Wind Turbine Main Shafts and other large-scale renewable energy equipment.
- Paper Mill Machinery and other heavy rolling mill applications.
