Lubricating oil for NTN bearing joints at high temperature of processing is of great importance

In order to guarantee the normal operation of NTN bearing, there must be a good lubrication, rated load and limiting speed of rolling bearings are under the assumption that lubrication to determine the appropriate conditions, the so-called lubrication is appropriate lubricant to choose appropriate, appropriate lubrication dosage, poor lubrication is often caused by one of the main cause of early damage of the bearing. According to statistics, about one-third of the bearing damage due to bad lubrication. When joint bearing temperature, the primary judgment can have no false move do first, and if the temperature is indeed rising, immediately do the following treatment: ( 1) Raid cooling water pressure, water flow and piping system can joint bearing in general. If water is likely to be lower filter blockage, means less than timely disposition of cylindrical hole bearing heat removal, can stop treatment, when confirm can work to do, then put into use. ( 2) When a raid of governor oil pressure, if low oil pressure can lead to cooling water hydraulic valve closed. ( 3) Raid can joint bearing no homophones UC204 90504 insert ball bearing, and detection of NTN bearing degree can not very. ( 4) Can take oil sample check color no change, joint bearings and test to see whether a variable. If confirm the degradation, when downtime to change new oil. ( 5) Can raid the oil standard oil level is general, if is general, raid tank emptying valve will shut. Joint bearing is not shut, when filling oil, if is sealant mat permeability oil, when stopping treatment. How of NTN bearing vibration is produced, try to avoid the phenomenon of joint bearing high temperature, adding its using life. NTN bearing in rotation, the bearing wear and failure due to friction. Hinder the joint bearing rotating by rolling friction, sliding friction and lubricant friction resistance of three kinds of. When the rolling element bearing rolling on rolling rolling friction; Cage guide roller in the surface, keep guard guide surface and roller bearing in the roller end face and ring is happening on the guard sliding friction; The lubricant friction by the lubricant at the contact of internal friction and lubricant of mixing and extrusion. Thus the impedance bearing movement friction resistance for the three combined. And the purpose of lubrication is grease and lubrication way avoid race, rolling element and cage direct contact between metal, reduce friction heat 'make to minimize friction, reducing wear and tear, prevent corrosion, prolong its service life.
