70/600 AGMB Bearing Product Overview & Core Advantages
The 70/600 AGMB is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rigidity and the ability to handle significant combined loads. Engineered with a 40° contact angle, it efficiently supports substantial axial loads in one direction alongside radial loads. Manufactured to P6 (ABEC-3) tolerance, this bearing ensures high running accuracy and is ideal for demanding, high-reliability machinery. Its robust construction and precise bearing dimensions (600mm bore, 870mm OD) make it a cornerstone for heavy-duty rotational systems.
70/600 AGMB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 70 | Series designation indicating specific internal geometry and load characteristics. |
| 600 | Nominal bore diameter in millimeters (600 mm). |
| A | Signifies a 30° contact angle (Note: Specification sheet indicates 40°, A typically denotes 30°; please verify design specifics for this model). |
| GM | Indicates the bearing is supplied with a moderate preload. |
| B | Denotes a 40° contact angle. |
70/600 AGMB Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The 40° contact angle and robust chrome steel construction enable this bearing to handle high radial dynamic load ratings of 198,900 lbf and radial static load ratings of 486,000 lbf, making it suitable for severe combined load conditions.
High-Speed Capability: The brass cage ensures stability and reduced friction at operational speeds, contributing to reliable performance. The specified limiting speed is 0.75 x 1000 rpm.
Precision & Rigidity: Manufactured to P6 tolerance with tight dimensional controls on bore, outside diameter, and width, this bearing provides high running accuracy and system rigidity, which is critical for precision applications.
Durability & Compliance: The use of high-grade chrome steel for rings and balls ensures long service life. The bearing is pre-lubricated and compliant with ROHS and REACH environmental standards.
