3 Hydraulic oil Hydraulic oil is a fluid used in the hydraulic equipment as a power transfer medium. It also works for lubrication, rustproof, and cooling. In order to take full advantage of the hydraulic equipment functions, it is important to select an appropriate hydraulic oil and to handle it properly. In addition, if the relief valve is operated continuously, or if the hydraulic oil temperature exceeds 60 C due to the frequent use of the pump, it is necessary to keep an appropriate temperature using an oil cooler.

As of January 31, 2016 Types of Hydraulic Oil and Compatible Packing Materials In some cases, it is necessary to use a flame-retardant hydraulic oil instead of a general hydraulic oil depending on the ambient conditions. If a flame-retardant hydraulic oil is used, the packing material must be changed according to the type of hydraulic oil. Type of hydraulic oil General hydraulic oil (mineral-based hydraulic oil) Compatible packing material Nitrile rubber (NBR) Data Application Examples Phosphate ester hydraulic oil (flame-retardant hydraulic oil) Fatty acid ester hydraulic oil (flame-retardant hydraulic oil) Fluoro rubber (FKM) Nitrile rubber (NBR) Vegetable oil (brake oil) Check the type of oil to be used. * If an hydraulic oil is used instead of a general hydraulic oil, parts may need to be changed as well as the packing material. Please contact us before use. Compatibility with Water-Glycol Hydraulic Fluid The compatibility of water-glycol hydraulic fluid with packing materials, metals, surface treatment, coatings is shown in the table below. Compatible Incompatible Packing material Nitrile rubber, fluoro rubber Polyurethane rubber, silicone rubber Metal Steel, tin, nickel, copper, etc. Zinc, aluminum, magnesium Surface treatment Nickel plate Galvanizing Coating Epoxy-based coating General paint coating (RIKEN standard coating) * If a RIKEN product is used with water-glycol fluid, modification may be needed depending on the model.

4 Table of Standard Bending Loads (Unit: kn) B R Plate thickness t (mm) Work piece: SS400 (tensile strength: 400 N/mm 2 ) Soft brass Soft aluminum Aluminum alloy Stainless steel Chromium molybdenum steel 50 % 50 % 100 % 170 % 200 % Bending load: kn/m Data 50 8 = B 8 t (Standard width of the lower die) Application Examples Example: The load required to bend an steel plate 3.2 mm thick and 3 m long can be obtained as follows The standard width B is approx. 8t 25. The table indicates the corresponding necessary load per meter as 275 kn. Accordingly, the total necessary load is 825 kn (275 kn 3 m). In this case, the internal R of the bent sheet is 4 mm or larger Simplified Chart of Bending Loads Corresponding to Thickness and Lengths <Description> When the t-axis (mm) and the L-axis (m) represent plate thicknesses and lengths respectively, if two points on the t-axis and the L-axis are connected with a line, the point of the intersection on the central axis represents the load kn. The chart shows that the width of the standard bending die is eight times the plate thickness, and that a mild steel of 370 to 410 N/mm 2 is bent to 90. Bending equation E.g.: When the plate is 1.2 mm thick and 2 m long F = Load (kn) T = Sheet length (mm) L = Bending length (mm) Fs = Tensile strength (N/mm 2 ) B = Lower die width (mm) R = Tip of upper die(mm) 225
