Why Choose Glparts Excavator Hydraulic Cylinders?

Glparts excavator hydraulic cylinders are engineered for strength, precision, and reliability. With piston diameters ranging from 2mm to 3mm, they are ideal for heavy-duty lifting applications. The 1/2-inch port size ensures broad compatibility with a wide range of hydraulic systems, making integration seamless and efficient.

Understanding that seal performance directly impacts cylinder longevity and system safety, we only use premium imported sealing components from trusted brands like SKF (USA) and NOK (Japan). This significantly reduces the risk of oil leakage, pressure loss, and premature seal failure, especially under extreme pressure and temperature conditions.

Our cylinders feature a threaded rod end design for easy installation and removal, minimizing machine downtime during maintenance or replacement. Both color and size can be customized to suit specific machine models or brand requirements, offering flexibility for diverse applications.

When you choose a Glparts hydraulic cylinder, you're investing in a component that enhances machine efficiency, extends equipment lifespan, and helps keep your projects running on schedule—all while backed by our commitment to strict quality control and responsive after-sales support.

Application

Our hydraulic cylinders are used in a wide range of construction and heavy equipment, including excavators, bulldozers, wheel loaders, backhoe loaders, and other types of machinery for construction, mining, forestry, agriculture, material handling, and demolition. Designed to withstand harsh environments like mud, dust, heat, and corrosive environments, our cylinders provide reliable performance and long service life even in the most demanding jobsite conditions.

Whether you're replacing your boom, stick, or bucket cylinder, or customizing a hydraulic solution for a new machine, Glparts offers the right solution with proven durability and compatibility with a wide range of excavator brands, including Komatsu, Hitachi, Caterpillar, Volvo, and Caterpillar.
