  • Super precision ball bearings ensure long life of

    2016-7-5 · A typical gyroscope application will incorporate two oil-lubricated open (not sealed) angular contact ball bearings with an oil sump between the bearings. This is sealed with a wick material that soaks up the oil and transfers it, drop by drop, to the bearings. This oil is returned back to the sump and the lubrication process is repeated.
