In fields such as infrastructure construction, building construction, and material handling, general hydraulic cylinders for construction machinery play a crucial role. Ruixin Hydraulic Machinery Co., Ltd. leverages accumulated industry experience to provide customers with a wide range of reliable general-purpose hydraulic cylinder products. This article aims to share knowledge on their typical applications and scientific selection.
General hydraulic cylinders are commonly used in equipment such as excavators, loaders, cranes, and bulldozers to achieve linear motions like boom lifting and lowering, bucket tilting, and outrigger extension and retraction. Several key parameters must be considered during selection: working pressure, stroke length, installation dimensions, load characteristics, and operating environment.
Working pressure is one of the core factors determining the structural strength of a hydraulic cylinder. Our product series cover a wide range from medium-low to high pressure. The materials and wall thicknesses of the cylinder barrel and piston rod are designed based on the rated pressure and safety factor. We recommend that customers select cylinders based on the actual maximum working pressure of the host system while retaining a reasonable safety margin to ensure long-term operational safety.
Stroke length and installation dimensions must match the design space of the equipment. We offer standard stroke products and also support customization according to customer drawings. Various installation forms are available, including clevis, flange, and foot-mounted types. When selecting, careful analysis of the force conditions and degrees of freedom at the equipment connection points is necessary to ensure smooth operation of the hinge points.
Load characteristics include load magnitude, direction, and motion speed. For conditions involving significant lateral forces or eccentric loads, reinforced piston rods, larger-sized guide sleeves, or external guide devices can be considered. For higher motion speeds, attention should be paid to cushioning design. Our cylinders can be equipped with internal cushioning mechanisms to reduce impact at the stroke ends, improving operational smoothness and component durability.
Environmental adaptability is equally important. In cold regions, low temperatures can affect the elasticity of sealing materials and the fluidity of hydraulic oil. We offer sealing combinations and port configurations suitable for low-temperature environments. In dusty or muddy construction sites, enhanced dust-proof designs and surface protection treatments are critical.
We recommend that customers provide detailed information about the host equipment’s operating conditions during selection, including equipment type, specific functions, typical work cycles, and ambient temperature and humidity ranges. Based on this information, our technical team can provide selection advice or customized designs to help you obtain products with a high degree of compatibility.
Consistent quality is essential for the continuous operation of construction machinery. Our production line utilizes automated processing and inspection equipment, combined with systematic quality control processes, to ensure the reliable performance of the cylinders delivered. Additionally, we emphasize product maintainability by adopting a modular design approach, making the replacement of wear parts such as seals more convenient, thereby helping optimize customers’ long-term operational costs.
