Changsha Ruichuang Hydraulic Technology Co., Ltd. is a professional manufacturer specializing in various hydraulic motors, hydraulic clutches, hydraulic rotary devices, electric transmission devices, hydraulic winches, hydraulic capstans, hydraulic stations, and complete hydraulic systems. With extensive design experience, advanced manufacturing technology, and a reliable quality assurance system, the company's products are widely used in engineering machinery, metallurgical equipment, petroleum, coal mining, geological exploration, railways, ships, environmental protection, machine tools, light industry, and plastic injection molding machinery. The YMD and YMS series swing hydraulic motors (also known as swing cylinders) are hydraulic actuators with an output shaft that performs reciprocating swinging motion. Their standout feature is the ability to directly provide reciprocating swinging motion to the load without the need for additional transmission mechanisms, with a swing angle that can be designed arbitrarily between 0~270 degrees. This product is an improved version based on the original YM series swing hydraulic motors, offering advantages such as compact size, lightweight structure, wide output torque adjustment range, and high positioning accuracy. It is applied in engineering machinery, agricultural and forestry machinery, petroleum, chemical, plastic machinery, and various automated production line tooling and industrial robotic mechanisms.
