Product Description

Hydraulic Cylinder for Excavator

•  The structural design is compact, using high-strength materials and special heat treatment and welding processes to ensure that the cylinder has an ultra long fatigue durability life under high pressure and heavy load.
•  The main seal adopts international first-class brand sealing products to ensure long service life.
•  We can provide various anti-corrosion treatment solutions for piston rods, including chromium electroplating, bronze electroplating, laser cladding, QPQ, ceramic spraying, etc.
•  Designed to withstand temperatures ranging from -25 °C to+100℃, customized cylinders can be provided according to user's requirements to meet higher or lower operating temperatures.

•  Design the buffer structure at the end of the cylinder stroke according to the requirements, so that the bucket can reduce the impact and noise of the cylinder during excavation operations, without reducing excavation force and affecting work efficiency.
•  Cylinders can be customized according to customer requirements such as working pressure, installation methods, size specifications, etc
