For hydraulic cylinders operating under heavy loads, alternating impacts and harsh environmental conditions, the quality of raw materials fundamentally determines the upper limit of product performance and service life.

Komatsu construction machinery, represented by the PC series excavators and HD series dump trucks, is widely deployed in global large-scale construction, open-pit mining and earthwork projects.

Volvo construction machinery, represented by the EC series excavators, is well recognized in the global market for its efficient fuel economy, smooth compound operation and intelligent hydraulic control system.

Hitachi construction machinery, represented by the ZX series excavators, is widely used in global construction, mining and municipal engineering scenarios.

Welding is a critical manufacturing process for hydraulic cylinders, as the welding quality of cylinder barrels, ear mounts, trunnions and other key components directly determines the overall pressure-bearing capacity, structural rigidity and service safety of the cylinder.

Caterpillar construction and mining equipment often operates in harsh environments with heavy load, frequent impact, high dust and large temperature difference.

Caterpillar equipment is widely deployed in global construction engineering and mining operations, and its hydraulic cylinder assembly serves as a core actuator that directly determines equipment working efficiency and on-site uptime.

As the core load-bearing moving component of hydraulic cylinders, the piston rod directly bears alternating loads, radial impacts and surface friction during long-term reciprocating operation, especially in engineering construction and mining scenarios.

The rear trunnion is a critical load-bearing connecting component for hydraulic cylinders used in engineering machinery and mining equipment.

As the core power component of heavy engineering and mining machinery, the Caterpillar Hydraulic Cylinder Assembly undertakes the key task of converting hydraulic pressure into linear mechanical motion, serving as the "power muscle" and control core of various heavy-duty equipment.

Beyond our standard product range, numerous specialized or innovative mechanical equipment have unique requirements for hydraulic cylinders. Leveraging flexible design capabilities and manufacturing resources, Ruixin Hydraulic Machinery Co., Ltd. provides customized hydraulic cylinder solutions for our clients.
