718/750 AGMB Bearing Product Overview & Core Advantages
The 718/750 AGMB is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. This precision bearing is designed to accommodate high combined loads, primarily thrust loads in one direction, while also supporting significant radial loads. Its 40° contact angle and P6 (ABEC-3) tolerance class ensure superior running accuracy and operational stability, making it ideal for demanding, high-rigidity systems.
718/750 AGMB Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 718 | Bearing series, indicating a specific internal design and performance characteristic. |
| 750 | Bore diameter in millimeters (750 mm). |
| A | Denotes a 30° contact angle (Note: Specification sheet indicates 40°, the 'A' suffix is a standard designation for angular contact bearings). |
| GM | Indicates the bearing is supplied lubricated. |
| B | Signifies a 40° contact angle, which provides higher axial load capacity. |
718/750 AGMB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a generous 40° contact angle is optimized to handle substantial one-direction axial loads and significant radial loads simultaneously. The optimized internal geometry, including the large shoulder diameters (807.3 mm inner, 863.2 mm outer), provides robust support and enhances system stiffness.
- Precision & Speed: Manufactured to a P6 (ABEC-3) tolerance class, this bearing guarantees high running accuracy. The brass cage ensures stability and reliable performance at the specified limiting speed.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and a long operational life. The pre-applied lubrication allows for immediate installation and initial operation.
718/750 AGMB Bearing Typical Application Areas
This bearing is suited for heavy-duty industrial machinery where high precision and the ability to withstand significant combined loads are critical. Typical applications include:
- Large Machine Tool Spindles
- Industrial Gearboxes
- Heavy-Duty Pumps and Compressors
- Mining and Construction Equipment
- Large Turntables and Indexing Tables
