1. The advantages of rolling bearings using smooth oil are:
1) Under certain operating standards; the smoothing of the starting torque and the loss of collision with smooth grease is significantly smaller than smooth grease.
2) Because the smooth oil takes away the heat in the circulation to cool the effect; it can make the bearing reach a relatively high transformation speed.
3) It can ensure that the higher operating temperature is reached.
4) When changing the fat; it is necessary to disassemble the relevant connecting parts; when the oil is smooth; there is no such trouble.
5) The bearings in the gearbox are very suitable when smoothing the smooth oil; the intention of the smooth gears and bearings is achieved by the splash together with the oil.
6) In the bearing, the smooth grease is gradually contaminated by the products worn by the product, the abrasive, the product soaked from the outside through the sealing device and the self-aging product; if not exchanged in time, the bearing is accelerated to wear; and when the liquid smoothing agent is used; Filter to make sure it works.
2, the smooth bearing strength of the rolling bearing:
1) Single bearing point; always need to add oil by hand; if you use grease, it will save energy and prevent the formation of trouble due to lack of oil.
2) The grease itself has a sealing effect; this allows the use of a tissue with a low degree of sealing to achieve a simplified depiction.
3) Experience has proved that in the range of certain speed (n<20000r/min or dn<20000mm.r/min), the lithium base grease has a lower temperature rise and a longer bearing life than the drop method.
