low temperature bearing

low temperature bearing

low temperature bearing

(OP)
Can you advice me for bearing working normal (easily)in extremly low temperature as -50C ? In additional the bearing is nested in aluminium body. When temeperature sinks to - 40...-50C because of different expansion Al housing tights the bearing which is made of steel. What would you advice me for lubricant too ?

RE: low temperature bearing

Is this a ball bearing? Are you asking for a bearing type?

Sometimes steel inserts are provided in aluminum and magnesium housings to help with the thermal expansion issues for warm housings. Seems like it would help when it's cold, too.  "Extra" clearance ball bearings are available.  

Does the "easy" operation mean the bearing in not likely to be generating a lot of heat when operating?

I bet Kluber has a grease for starting and running at low temps.

Is it always that cold?

RE: low temperature bearing

(OP)
Yes, I mean ball bearing, but type could be changed if necessary.
The bearing rotates relatively slowly max 10-12 rpm or very slowly 0.5 rpm.
It is not always so cold, may be only at nights. This is appliance which is assigned to work in polar areas.
I found Kuber's grease works good.
Thanks for help.
