The application of antiwear agents in bearings

The lubrication problem of mill support roller bearing is a problem dire need to solve. The rod mill bearings is for low-speed, heavy-duty lubrication. Problems rolling mill bearing prevalent in China includes: first, boundary lubrication problem; second, strong impact load; third, water and debris intrusion and cooling problems. Due to the existence of these three issues, imported bearing wear is serious, even appears axle phenomena, which need often down for maintenance, oil changes, the production is affected and economic losses is large.
In order to solve the above problems, many units did research and there were a lot of programs, but still not very satisfactory. The method of using nano antiwear (extreme pressure) agents makes significant effectiveness.
Nano antiwear agents, is a nano-type ball (extreme pressure) antiwear agent. Its compressive strength is up to 1500MPA/CM2, it nonseizure load is also very high, as two to three times of the gear oil in the past. Similar tests done by the University, adding to 6 to 12% of the 8O8 Nano anti-wear agents can greatly improve the lubrication, compression, shear, pitting, peeling, overheating and other problems thus several times to extend bearing life, reduce noise, take smooth operation and save power. The power consumption, vibration, noise and bearing temperature decline with varying degrees. Similarly, it can be divided into several added to the grease. Its mechanism of action is: 8O8 nm antiwear agents can produce nano-reactive membrane at a contact point in the operation of the process, its strength is much higher than traditional chemical reaction film, it could be firmly adhered on the bearing and produce nano ball, so that enhance and improve the mill lubrication problems.
