Applications

In general, bearings used for aerospace and aeronautic applications are critical components designed with exacting tolerances to meet the demands of ultra-precise applications and superior rotational accuracy. Also, these high-performing bearings must be reliable and durable enough to withstand immense pressure and force, drastic thermal changes, and extreme friction and wear that are required. To improve fuel efficiency, reduce labor costs by extending maintenance intervals, and lowering carbon emissions, both fixed-wing and rotary-wing aircrafts rely on bearings that offer high‑load capacities while saving space and reducing weight. In addition, aerospace ball and roller bearings must offer long service life and be virtually maintenance-free.
