Industrial Uses of 70/900 AMB Bearing
The 70/900 AMB Bearing is commonly used in large industrial machinery, such as heavy-duty presses and rolling mills, where its angular contact design handles combined radial and axial loads efficiently.
With a 40° contact angle, it’s well-suited for applications requiring precise alignment, like wind turbine gearboxes or mining equipment. The brass cage adds durability in high-load scenarios.
Why Is 70/900 AMB Bearing Essential in Machinery?
In steel production plants, 70/900 AMB Bearing supports massive rollers, ensuring smooth operation under extreme loads. Its P6 tolerance class provides the precision needed for consistent performance.
The open design allows for easy lubrication, extending service life in harsh environments like cement kilns or paper mills. Its chrome steel construction resists wear even in high-temperature conditions.
Built for Heavy-Duty Use: 70/900 AMB Bearing
This bearing excels in applications like ship propulsion systems, where its large bore (900mm) and static radial load capacity (1,102,500 lbf) handle significant stresses.
The metric sizing makes it interchangeable with major brands, simplifying maintenance in global industrial projects. Its lubricated design reduces friction, ideal for low-speed, high-torque operations.
Automotive vs Aerospace: Applications of 70/900 AMB Bearing
While too large for standard vehicles, 70/900 AMB Bearing fits specialised transport like railway axles or marine engines, where its angular contact design manages directional forces.
In aerospace, it’s occasionally used in ground support equipment, though its weight (665kg) limits airborne applications. The brass cage ensures reliability in vibration-heavy environments.
