Hollow Plunger Type Hydraulic Cylinders For Excavator
Established in 2011, JSRUIYA Hydraulic Machinery is a professional manufacturer and exporter of hydraulic cylinders, hydraulic power unit and hydraulic accessories.
Based on 9 years of manufacturing experience, with ISO 9001:2008 Quality Management System, more than 80% of our products are exported to US, Canada and Australia.
JSRUIYA brand cylinders have been widely used in machinery industry, metallurgy industry, agricultural equipment, construction equipment, mining equipment, food industry, forestry equipment, trailers, excavators and other fields.
The plunger type hydraulic cylinder is a single-acting hydraulic cylinder, which can only achieve movement in one direction by hydraulic pressure. The return stroke of the plunger depends on other external forces or the weight of the plunger;
The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so that the cylinder sleeve is extremely easy to process, so it is suitable for a long stroke hydraulic cylinder;
The plunger is always under pressure during operation, so it must have sufficient rigidity;
The weight of the plunger tends to be large. When it is placed horizontally, it is easy to sag due to its own weight, causing the seal and the guide to wear on one side, so it is more advantageous for vertical use.
