■Performance comparison of plate materials. OILES #2000 (sintered layered plate) This product maintains superior wear resistance in low to high load applications. When compared to both the OILES #500F and the OILES #500SP, this product has twice the wear resistance and galling resistance. By mating two #2000 plates together even higher loads can be obtained. OILES #500F (cast iron type plate) With a cast-iron base, the material cost can be reduced by using this low-load product. OILES #500SP (High-strength brass type plate) With wear resistance that is close to that of the OILES #500F, this item feature higher galling resistance. In high load conditions it is susceptible to faster progression of wear. This is a general characteristic of brass. In low-load area, wear volume is kept low due to the formed oxide film. On the contrary, in high-load area, oxide films are peeled, and metals contact to each other, leading to higher wear.
