Drone Bearings
A drone is an application that forces five demands—light weight, high rotational speed, low noise, weather resistance, and reliability—into one small bearing at the same time.
These five pull against each other: shave material for weight and you may lose stiffness; pick low friction for high speed and you may compromise the seal that gives you weather resistance; add protection for the elements and the weight creeps back up.
This article is written for the product development, R&D engineering, and industrial procurement teams building drones, gimbals, powertrains, or related drive modules.
ISK Bearings, as an integrated bearing solutions provider, has put together the selection questions drone applications most often run into—and the conditions worth clarifying before the spec is finalized.
