Custom paint and packaging options are also available. 3D CAD models are available upon request.
Wide variety of custom cylinders are manufactured, including single stage cylinders (both single and double acting), single and double acting telescopic (small and large bore), double end cylinders, piggyback design, mill type cylinders, tie rod cylinders, accumulators, marine grade steering cylinders, and standard dimension welded product 
Product Description
The telescopic hydraulic cylinder is designed for applications requiring long and short strokes. Inner threaded head makes it easier to remove head and stem seals without special tools or retaining rings. Redundant rod seals improve seal and pressure capabilities and provide a buffer against peak pressure. The telescopic hydraulic oil cylinder suitable for mining, public utility, public service, road construction, waste and garbage, oil and gas, military, transportation, road service, material handling and other fields.
Telescopic hydraulic cylinder can get a longer working stroke with multi-stage sleeve-shaped piston rod hydraulic cylinder, also known as multi-stage hydraulic cylinder.It is composed of two or more piston hydraulic cylinder set, the piston rod of the previous stage piston cylinder is the cylinder of the latter piston cylinder.
Therefore, the slow out faster, the corresponding hydraulic thrust from large to small; this thrust, speed changes, is suitable for a variety of automatic loading and unloading machinery on the thrust and speed requirements. The order of retraction is generally followed by small to large retraction, the retraction of the axial length is shorter, smaller footprint, compact structure.
Commonly used in construction machinery and other mobile machinery, such as cranes, dump trucks and other hydraulic systems. Our clients can avail this Telescopic Hydraulic Cylinder from us at the most reasonable price. If for any reason you feel otherwise with your purchase, contact us and we will be there for you.

Quality Control:
1. The mechanical properties and chemical elements of the raw material will be inspected to check whether qualified after entering the warehouse.
2. Chemical composition inspection of raw materials, Test the chemical composition of metallic materials, such as C, Si, Mn, P, S, Cr, Ni and other elements. Mainly for raw materials incoming inspection, by testing whether the material qualified, receiving materials.
3. Metallographic analysis of metal materials is usually the raw materials, such as copper, iron, aluminum, magnesium, zinc, titanium, etc., for the processing of structural parts and finished product evaluation, through the metallographic analysis.
You can find a variety of possible reasons for failure analysis in time, Prediction and analysis the characteristics of metallic materials and materials, Study material surface, and internal defects, and to improve and verify the process technology of the material.
4. Salt spray test is a major use of salt spray test equipment created by the artificial simulation of salt spray environmental conditions to assess the corrosion resistance of products or metal materials, environmental testing.
