719/500 AGMB Bearing Product Overview & Core Advantages
The 719/500 AGMB is a single row angular contact ball bearing designed for exceptional precision and performance in demanding applications. Engineered with a 30° contact angle, this bearing is optimized to support combined loads, handling significant axial loads in one direction alongside radial loads. Its P6 (ABEC-3) tolerance class ensures high running accuracy, making it ideal for applications requiring high rigidity and precise shaft guidance. The open design, combined with a brass cage, facilitates high-speed operation and reliable performance within a wide temperature range.
719/500 AGMB Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 719 | Series designation for high-precision angular contact ball bearings. |
| 500 | Nominal bore diameter in millimeters (500 mm). |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| GM | Indicates a brass cage (machined window-type), which provides strength and stability for high-speed applications. |
| B | Designates a P6 tolerance class (equivalent to ABEC-3), ensuring high precision and dimensional stability. |
719/500 AGMB Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The 30° contact angle and robust construction enable the bearing to efficiently handle combined radial and axial loads. With a high dynamic load rating of 124,425 lbf and static load rating of 274,500 lbf, it offers reliable performance under heavy-duty conditions.
High-Speed Capability: The brass cage (GM) ensures low friction and excellent dimensional stability at high rotational speeds, contributing to a limiting speed of 1,000 rpm. The open design allows for effective lubrication management, further enhancing high-speed performance.
Precision and Rigidity: Manufactured to P6 tolerance, this bearing guarantees precise running accuracy and minimal vibration. The defined shoulder diameters on both rings (Inner: 557 mm, Outer: 616.3 mm) facilitate accurate positioning and contribute to system high rigidity.
Material and Durability: Constructed from chrome steel for both rings and balls, the bearing provides high wear resistance and long service life. It operates effectively within a temperature range of -30°C to 110°C.
719/500 AGMB Bearing Typical Application Areas
The 719/500 AGMB is suited for heavy-duty, precision machinery where high axial load capacity and speed are critical. Common applications include:
- Machine Tool Spindles
- Industrial Gearboxes
- Large Pumps and Compressors
