Difference in Performance Resulting from Differences in Materials: Test Results for Flat Surface Reciprocating Movements Total amount of wear (μm)  Galling Pressure Bronze graphite FC Graphite Product type (Product name) FC + Graphite Plate (OILES #500F) Bronze + Graphite Plate (OILES #500SP) Special Sintered Alloy Graphite OILES (#2000) Single Double Feature Exterior appearance Wear resistance Galling resistance Ease of additional machining Servise temperature range Allowable pressure P:N/mu(kgf/cu) Wear resistance is great under low pressure conditions. However, galling occurs more easily during times of high pressure. Galling does not occur even under high pressure conditions. However, the progression of wear occurs quickly. Makes it difficult for galling to occur under high pressure conditions and feature superior wear resistance. Makes it difficult for galling to occur under ultra-high pressure conditions and feature superior wear resistance. *Materials for additional machining (CWI Standard) may be machined at the discretion of customers. *Even when using Standard product plates (CWP, CWPT, CWXT, CWA, CWT and CWI) subject to additional machining (L-width cut), they may be used without worrying about the loss of solid lubricant. *Initial lubrication required.
