70/500 AM Bearing Product Overview & Core Advantages
The 70/500 AM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional rigidity and accurate rotational guidance. Designed to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction—this bearing is ideal for demanding arrangements. Its P6 (ABEC-3) tolerance class ensures superior running accuracy, while the optimized 30° contact angle provides excellent axial load capacity. Manufactured from high-grade chrome steel and featuring a robust brass cage, it delivers reliable performance in high-speed and high-stiffness operational environments.

70/500 AM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and high-quality chrome steel construction, provides outstanding rigidity. It supports substantial combined radial and axial loads, with a dynamic load rating of 160,875 lbf and a static load rating of 360,000 lbf.
- Precision & High-Speed Operation: Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures minimal vibration and precise shaft positioning. The brass cage contributes to stable operation at the specified limiting speed.
- Optimized Internal Geometry: Critical dimensions such as the shoulder diameters (outer ring: 640 mm, inner ring large-side: 587 mm) and the distance from side face to load point (226 mm) are engineered for optimal load distribution and secure mounting in precision machinery.
- Broad Operating Range: Suitable for a temperature range from -30°C to 110°C, ensuring performance stability across various industrial environments.
