| 718 | Bearing series, indicating a specific internal design optimized for high-precision and high-speed applications. |
| 850 | Bore diameter in millimeters (850 mm). |
| AMB | Suffix indicating the bearing is pre-lubricated with a specific high-performance grease. |
718/850 AMB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to handle high unidirectional thrust loads and substantial radial loads simultaneously. The robust chrome steel construction of rings and balls ensures dimensional stability under heavy combined loads.
- Precision Performance: Manufactured to a P6 (ABEC-3) tolerance class, this bearing guarantees high running accuracy and minimal vibration, which is critical for the smooth operation of precision machinery.
- Optimized Cage Design: The brass cage provides excellent guidance and stability for the balls, contributing to reliable operation and extended service life.
- Ready-to-Install Convenience: The bearing is pre-lubricated (AMB suffix), simplifying installation and ensuring immediate, optimal performance upon startup.
718/850 AMB Bearing Typical Application Areas
This angular contact ball bearing is ideally suited for heavy-duty, precision applications, including:
- Large Machine Tool Spindles
- Industrial Gearboxes and Power Transmission Systems
- Heavy-Duty Pumps and Compressors
- Large Bore Precision Instruments and Test Rigs
