MSI’s hydrodynamic (self-acting) compliant foil bearings generate their own load-carrying film from the rotation of the shaft it supports. A smooth top foil forms the bearing surface, and a flexible “bump” foil provides this surface with controlled, resilient support.
This proprietary design ensures a “self-adjusting” bearing with inherent internal damping that adapts to shaft misalignment, variations due to tolerance buildups, centrifugal and thermal shaft growth, and differential thermal expansion. Large or small, our foil bearings can provide the performance you need for specialized high-speed or extreme-temperature machinery.
Whether you need a new design or retrofit to an existing machine, our experts will analyze, design, and manufacture foil bearings tailored to the unique rotordynamics of your machine and its application. We have a library of designs to start from, and can often utilize an existing design if the application is somewhat flexible. We will always work with our customers to determine what makes the most sense for them.
MSI has decades of experience designing, building and testing foil bearings for a wide variety of systems, including for rotating machines that we design ourselves. Because of this, we can support our customers with as much or as little of their machinery development effort as they like, from conceptual design to prototype testing.
We are very flexible in terms of technology transfer. We realize bearings are literally supporting YOUR idea, and not the other way around. We have a wide variety of technology transfer and manufacturing options to support getting your solution to market.
