Extremely low temperature bearings?
Extremely low temperature bearings?
(OP)
I've been asked to build a device that operates in a -100 degree F environvment. The mechanism requires 10 rotational bearings, they could be plain, roller, ball etc... I simply can't find bearings that are rated for these kinds of temperatures. Has anyone had any experience with something of this nature or have any ideas? Thank you!

the operating loads for the bearings will be in the area of 750lbs, oscilating motion 0 to 90 degrees with intermittent use, approximately once every 2 hours. The environment involved has a tendancy to coat anything within it with a half an inch of fine ice from the humidity in the air.

The only thing that worries me is your mention of water ice forming on the equipment. Ice in a bearing bad in that it can cause the ball or roller to skid instead of rolling especially in intermittent operation.
I would also give GGB a call and discuss your requirements.
Here are two groups of bearings that may have possibility of working.

answer. Nice to have something off the shelf to save costs.

Hope that's not too wild.
