Step (1) Select the bore size of air-hydro cylinder First of all, select a bore size from data (D) . When making a selection, the ratio between the theoretical output and the load should be 0.5 or less. 1. Make sure to select a cylinder and a rotary actuator for an air-hydro operation. Do not use these for pneumatic operations because they will lead to oil leaks. Air-hydro cylinder: CA1H- CQ2H- CS1H- CM2H- CG1H- (up to o63) HC03-X1- x Air-hydro rotary actuator: CRA1H- 2.When determining the size of a converter based on the , do not select a converter bore that is too small for the cylinder’s bore size because this will increase the oil level speed, causing the oil to blow out. Thus, select a converter bore, so that the oil level speed will be 200 mm/s or less. Refer to the table below for the relationship of the converter size, cylinder bore size and cylinder piston speed, which make the oil level 200 mm/s or more. When the cylinder piston speed becomes more than those listed in the table below, select a converter one size bigger. Caution on Selection Converter size Cylinder bore size (mm) Cylinder piston speed (mm/s) CCT40 CCT63 o32 o40 o50 o63 o80 o100 310 or more 200 or more 315 or more 200 or more 120 or more 75 or more Step (2) Select converter Select the nominal diameter and the effective oil level stroke from data (A), . When selecting a converter by its nominal diameter, the converter’s oil level speed should be 200 mm/s or less. When the cylinder stroke is beyond , select a converter capacity that is 1.5 or more times larger than the cylinder capacity as a guide. Step (3) Select required function for valve unit Select a model from data (B), by determining the functions that are needed for the valve unit in accordance with your application. Step (4) Select the size of valve unit Using data (C), as a reference, select the size of a valve unit by determining whether it meets the desired cylinder operating speed. . The model of an air-hydro unit that is suitable for a particular application is determined by the combination of the converter that was selected in steps (1) and (2), and the valve unit that was selected in steps (3) and (4). For details on how the models are indicated, refer to “How to Order”. Series CC Selection Procedure 1152
