70/1000 AMB Bearing Product Overview & Core Advantages
The 70/1000 AMB is a single row angular contact ball bearing engineered for demanding applications requiring exceptional precision and reliability. This precision bearing is designed to accommodate high combined loads, specifically substantial axial loads in one direction alongside radial loads. Its robust construction, featuring a brass cage and a generous 40° contact angle, delivers high rigidity and stable performance under challenging operational conditions. Manufactured to a P6 (ABEC-3) tolerance class, it ensures precise running accuracy for critical machinery components.
70/1000 AMB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 70/1000 | Bearing series and bore diameter (1000 mm). |
| AMB | Specific manufacturer series designation for this angular contact design. |
| Open (Seal Type) | No integral seals, designed for systems with external sealing or controlled environments. |
| P6 (Tolerance) | Denotes a precision tolerance class equivalent to ABEC-3, ensuring tight dimensional control. |
70/1000 AMB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to handle significant combined loads. This configuration provides excellent resistance to deflection, ensuring high rigidity for stable shaft support.
- Optimized for Precision: The machined brass cage provides superior guidance and stability for the balls, contributing to smooth operation and reduced vibration, which is critical for precision bearing applications.
- Material Integrity: Constructed from chrome steel for both rings and balls, this bearing offers high fatigue resistance and durability, supporting the high radial dynamic load rating of 366,750 lbf.
- Pre-Lubricated for Immediate Service: The bearing comes lubricated from the factory, ready for installation and initial operation within its specified temperature range of -30° to 110 °C.
70/1000 AMB Bearing Typical Application Areas
This large-bore angular contact ball bearing is ideally suited for heavy-duty industrial machinery where high axial and radial load capacity is paramount. Key applications include:
- Large Gearboxes and power transmission systems
- Heavy-Duty Industrial Pumps and compressors
- Main spindles in large-scale machine tools
- Critical rollers in metal processing equipment
- Support bearings in wind turbine gearboxes
