70/800 AMB Bearing Product Overview & Core Advantages
The 70/800 AMB is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional rigidity and load capacity. This precision bearing is designed to accommodate combined loads, primarily handling significant thrust loads in one direction alongside radial loads. Its open design and P6 (ABEC-3) tolerance class ensure superior running accuracy, making it ideal for high-reliability machinery where precise shaft guidance is critical. The large bearing dimensions (800 mm bore) and robust construction provide a stable and durable solution for heavy-duty industrial equipment.
70/800 AMB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 70/800 | Standard designation indicating a 800 mm bore diameter bearing. |
| AMB | Manufacturer-specific series code for this angular contact bearing design. |
| Open | Indicates the bearing has no seals or shields, allowing for optimal lubrication flow and heat dissipation, suitable for controlled environments. |
| P6 | Specifies the tolerance class, equivalent to ABEC-3, ensuring high dimensional and running accuracy. |
| Lubricated | The bearing is supplied with initial lubrication suitable for a wide temperature range of -30° to 110 °C. |
70/800 AMB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, with a optimized contact angle and large shoulder diameters (923 mm inner, 1033.84 mm outer), provides exceptional resistance to deformation under heavy combined loads. It offers a substantial radial dynamic load rating of 281,250 lbf and a radial static load rating of 821,250 lbf.
- Precision Performance: Manufactured to a P6 tolerance class from high-grade chrome steel, this bearing guarantees low noise, smooth operation, and precise rotational accuracy, which is critical for applications like machine tool spindles.
- Optimized for Heavy-Duty Use: With a large distance from side face to load point (359 mm), the bearing provides a wide load spread, enhancing stability and service life in demanding conditions.
70/800 AMB Bearing Typical Application Areas
This large-bore angular contact ball bearing is ideally suited for heavy machinery and precision equipment, including:
- Large Machine Tool Spindles and rotary tables
- Industrial Gearboxes and power transmission systems
- Heavy-Duty Pumps and compressors
- Mining and Construction Equipment
- Wind Turbine Main Shafts and pitch control systems
