Thin oil lubrication of the track roller bearings: the advantage is that the internal friction coefficient is small, so it consumes less energy to overcome friction, has good fluidity, is easy to enter the friction surface of each lubrication point, has good cooling effect, and the oil lubrication of the track roller bearing can take away the impurities adhered to the friction surface and the metal particles produced by grinding. The disadvantage is that the oil film can not bear large unit pressure and has high requirements for sealing. High speed presses generally use large flow of thin oil lubrication, which can take away the heat generated by each friction pair.
