Dry Lube for High Precision Bearing
Dry Lube for High Precision Bearing
(OP)
Were in the process of designing an optical instrument housing, and are considering a high-precision bearing (ABEC 5) for a rotating fixture.
The bearing has minimal clearance (0.0002"). The torque on the bearing is extremely low, around 3-5 ounce-inches (assuming no pre-load via interference fit).
Since it is lab equipment, we would like to use a dry lube, and were thinking of Sprayon T.F.E.
Does anyone have a better recommendation, or is a light instrument oil required for this application?
Thanks for your help.

I had an application where we had to demonstrate start up at -40C. Petroleum base grease caused lock-up. PAO performed without lock-up with half the starting amps.

The graphite based lubricant is a solid that fills the cavity between the rolling elements and the inner and outer race.
