I am working on a piece of art that has parts that rotate slowly, at about 1RPM, thanks to a couple of bearings. There is a possibility that it might be installed beside a beach for about a week. The problem is that sand and bearings do not play together well.
Or do they? Is there a bearing type that can resist the ingress of sand, or failing that, a reasonably reliable and durable way of preventing sand entering?
Yes, I am considering covering it with boots, but this question is part of research to see if there is an alternative.
