7072 AM Bearing Product Overview & Core Advantages
The 7072 AM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional rigidity and accurate rotational performance. This metric bearing is designed to accommodate combined loads, specifically handling substantial radial loads and unidirectional axial loads simultaneously, thanks to its defined 30° contact angle. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and is ideal for demanding scenarios in industrial machinery. Its open design allows for customized lubrication solutions, providing flexibility for various operational environments.
7072 AM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| AM | Indicates a specific internal design and contact angle (30°), optimized for high rigidity and precise axial load capacity. |
Note: This is an open bearing with no integral seals or shields, offering maximum design flexibility for lubrication systems.
7072 AM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 30° contact angle and a brass cage provides excellent stability, enabling the bearing to support high dynamic and static load ratings (117,000 lbf and 213,750 lbf respectively).
- Precision Performance: Built to P6 (ABEC-3) tolerance standards, it guarantees minimal runout and superior rotational accuracy for high-speed applications up to 1,300 rpm.
- Robust Construction: Components made from chrome steel for both rings and balls ensure high durability, wear resistance, and a long operational lifespan under demanding conditions.
- Optimized Geometry: Precise shoulder diameters on both the inner and outer rings facilitate accurate axial positioning and secure mounting.
