1 tolerance: general bearing, inner ring rotation relative to the outer ring, with tighter.The outer loose. The main reason is the outer ring plays a supporting role, no rotational force big.
(micro, outer ring relatively peristalsis, but not much) RE type bearing is just the opposite, namely two ring bearing force just the opposite. So, tolerance to the contrary. Active rotation
The ring fit will be relatively tight.
2 clearance: clearance basically selection and temperature and tolerance related. If only the outer ring of bearing tolerances for the elastic case, then influence the changes before and after not Is particularly high (but certainly, the precision can not be ignored), generally can be considered and the general bearing, because tolerance variations. As for the temperature, which completely and a revolving around it doesn't matter, mainly to see the external heat source. So there is no too much change. In a word, cross roller bearing clearance basically can choose to speed, temperature standard.
3 lubrication, should pay attention to, if the seal bearing, please do not use the dust cover, bearing will spill. To choose the rubber seal. If open bearing, a general note,then
Lubrication time interval to adjust for the past half. bearing with grease lubrication and lubrication of the sealing rubber ring double, ensure the lubrication effect of high precision bearings.
