Although our products are designed on the basis of our profound knowledge and long experience, and manufactured under the strict quality control system, the following must be taken into consideration in actual use. The operating conditions of the products shown in this catalog vary depending upon each ap-plication. Therefore, the decision of the products' suitability to the system considered must be made by the designer of the hydraulic system and/or the person in charge of determining the specification after making analysis and conducting tests, if necessary. The study of the specifi-...

As shown in the right, the high pressure oil passes through the inlet port (a) and flows into the cylinder block (2). Hydraulic force thus acts upon the piston (4), generating an axial force F. This force F is vector-analyzed through the shoe (5) into force F1 which is perpendicular to the swash plate (7), and force F2 which is a vertical force with respect to the output shaft. The reaction force of force F2 is transmitted via the piston to the cylinder block, generating a rotational force which turns the output shaft. These are 9 equally spaced pistons in the cylinder block. The pistons...

WARNING Before operation, be sure to fill the casing with oil through the drain port . Vent all air out of the motor and hydraulic circuit prior to operation. The insufficient amount of oil may cause the lubrication failure, resulting in the seizure of internal parts. The volume of the oil is shown in the SPECIFICATIONS as case volume. > WARNING This brake should be used only for parking, are not for dynamic braking. In case of driving inertial load, measures such as the adoption of the time delay valve should be taken to prevent the parking brake from being activated before the inertial...
