Vertical grinding roller in the ore powder or coal powder inside the mill, it is difficult to seal, demanding, is also very important, both to prevent oil spills, but also to prevent dust into. If the seal is not good, cause oil leakage or dust into the roller bearing, the bearing will abrasion that grinding roller can not operate normally and downtime, even to replace the bearings, production downtime, time-consuming, resulting in greater losses. The working condition of the sealing ring is high, and the material requirements are very strict.
Temperature resistant -70 DEG C to 300 C, oil resistance, acid and alkali resistance, corrosion resistance, aging resistance.
It is suitable for sealing all kinds of lubricating oil, fuel oil, gasoline, hydraulic oil and synthetic oil.
