70/850 AMB Bearing Product Overview & Core Advantages
The 70/850 AMB is a metric single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and load capacity. Designed to accommodate combined loads (simultaneous radial and axial forces), this bearing features a P6 (ABEC-3) tolerance class for superior running accuracy. Its robust construction ensures high rigidity and stable operation, making it ideal for demanding industrial environments where reliability is paramount. The bearing comes pre-lubricated for immediate service.
70/850 AMB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 70/850 | Bearing series and bore diameter (850 mm) |
| AMB | Manufacturer's internal designation for angular contact design and specific internal geometry |
Key Configuration: Open seal type (no physical contact seals) for minimal friction and heat generation, suitable for controlled environments. Standard lubrication is applied for initial operation.
70/850 AMB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with optimized raceway geometry and a substantial 381 mm distance from side face to load point, provides exceptional resistance to deformation under heavy combined loads. It supports a radial dynamic load rating of 310,500 lbf and a radial static load rating of 933,750 lbf.
- Precision Performance: Manufactured to P6 (ABEC-3) tolerance class, this bearing ensures precise shaft guidance, reduced vibration, and consistent performance in high-accuracy machinery.
- Material & Durability: Constructed from chrome steel for both rings and balls, offering high hardness, wear resistance, and a long operational lifespan under demanding conditions.
- Thermal Stability: Operates effectively within a temperature range of -30°C to 110°C, maintaining performance across various industrial climates.
70/850 AMB Bearing Typical Application Areas
This large-bore, high-capacity angular contact ball bearing is specifically suited for heavy-duty industrial equipment, including:
- Large Industrial Gearboxes and power transmission systems
- Heavy-Duty Machine Tool Spindles requiring high rigidity and precision
- Mining and Construction Machinery main shafts and pivot points
- Large Pumps and Compressors handling significant radial and axial forces
- Wind Turbine Main Shafts and pitch/yaw control mechanisms
