Sulli Xiaosu: Inferior bearing lube is used what to cause to endanger to bearing below detailed today introduction.
Bearing oil is the special lubricant of accurate machine tool and bearing of similar device main shaft, its working precision to assuring main shaft and performance characteristics, lengthen its service life to having very main effect. So of lube choosing is all in all.
Lubricant action(1) the departmental cent of lubricant bearing, ball of the circumgyrate attrition that reduces raceway groove face and steel ball, steel and maintain implement sliding friction, maintain implement with the sliding friction inside raceway groove spigot surface
(2) the heat that takes away bearing interior attrition to happen and other from exterior the heat that transmits, those who prevent bearing is calorific the deterioration with lubricant
(3) make the scroll interface of bearing often forms proper oily film, alleviate concussion bear centers stress and the fatigue life that prolong bearing
(4) prevent steel ball, raceway groove, maintain implement rustily and of rubbish, eyewinker, moisture invade.

Lube 5 big functions(1) lubricant: Offer the lube film of detached attrition surface, cold start-up wears away take engine overall tatty 70 ％ .
(2) clean: From bearing lubricant place cleans contaminant come down, become extremely subtle grain eduction dispersedly.
(3) cooling: Reduce the quantity of heat that produces because of attrition, pass quantity of heat the loop to take away and cool.
(4) anticorrosive: Avoid air and water to the component corrode.
(5) sealed: Prevent blow-by.
Good lube is had above 5 big functions, but if use character bad lube or use method is undeserved, can bring a few issues to engine.

The harm of inferior lube(1) burn plain bearing liner: If choose lube quality is bad, the lube viscosity that perhaps chooses is incorrect, lubricant result is bad. And oil pressure crosses low, engine to be short of breakdown of oily, cooling system to wait to be able to cause engine overheat again. Below this kind of circumstance high speed runs, burn out bearing easily, common says " burn tile " . Additional, if used core of filter of inferior engine oil,perhaps did not change on time core of engine oil filter, still can make foreign matter places amid, cause " burn tile " .
(2) snap ring: If the cleanness of lube is dispersive the gender is bad, after be being used for a long time, can be all round piston annulus generation carbon deposit, and piston annulus can be caused to card dies or break off when carbon deposit is serious.
(3) engine oil has used up big: If of lube fight abrasiveness can bad, can make between piston annulus and air cylinder wear away aggravate, oily annulus blows oily action abate, make engine oil enters firebox to attend combustion, generation vent-pipe risks the phenomenon of blue smoke. If the sealed and bad, valve of engine blocks oily annulus invalidation to wait to also can cause engine oil leakage, meet those who accelerate engine oil use up likewise.
(4) engine oil lamp calls the police: Once produce this kind of phenomenon to basically seek an account in the following respects: Lube is insufficient (add) ; A place of strategic importance of engine oil induction damages (change) ; Screen pack of lubricating oil pump jams (clean) ; Lube viscosity is insufficient (change lube or examination have without) of fuel dilute and engine overheat phenomenon; Invalidation of bedspring of engine oil pressure limiting valve (clean change) .
