Excavator hydraulic cylinders are exposed to a wide range of working environments, from dusty construction sites and high-temperature mining zones to freezing winters in mountainous regions. At GLPARTS, our cylinders are engineered to deliver stable performance, extended service life, and reduced maintenance needs — even under the most demanding conditions.
How to deal with high temperature
GLPARTS uses heat-resistant sealing systems (including Japan NOK and US SKF materials), high-frequency surface-hardened piston rods, and enhanced chrome plating to prevent wear, oxidation, and seal deformation. This ensures smooth operation and leak-free performance, even when exposed to continuous high-pressure cycles and ambient temperatures exceeding 50°C.
How to deal with low temperature environment
To address this, GLPARTS cylinders can be equipped with cold-weather adaptive seals, precision-machined internal clearances, and low-temperature hydraulic oil compatibility. These features help maintain consistent piston movement and quick pressure response, reducing downtime during winter operations.
