These drilling machine hydraulic cylinder are made from high quality raw materials and all the drilling machine oil cylinder we provide are widely used in various types of drilling machines to achieve high durability. In addition, a diligent team of experts ensures that only high-quality materials are delivered within the promised time and place of the customer.

As the main parts of hydraulic cylinder, single pillar for mining, hydraulic support, gun pipe and other products, the processing quality of cylinder directly affects the life and reliability of the whole product. The processing requirements of cylinder barrel are high, and the internal surface roughness requirements are Ra0.4 ~ 0.8&um, and the requirements for coaxial degree and abrasion resistance are strict.

Our company's drilling machine hydraulic cylinder products mainly adopt rolling process, because the surface layer has residual surface compressive stress, which is conducive to the sealing of small cracks on the surface and hinders the expansion of erosion. 

In this way, the anti-corrosion ability of the surface can be improved, and the fatigue crack can be delayed or expanded, so the fatigue strength of cylinder can be improved. Roll forming, by forming a layer of cold work roll surface hardening layer, reducing the grinding pair of elastic and plastic deformation of the contact surface, thus improve the wearability of the inner wall of the cylinder, at the same time avoid the burn caused by grinding. After rolling, the surface roughness can be improved by decreasing.

Product Advantages:

Drilling machine hydraulic cylinder is a special oil cylinder for crawler drilling rig. Engaged in rock blasting, anti-seepage grouting holes, grouting holes foundation implementation, surface mining, defense projects and other drilling operations. 

The technical problem of difficult hole formation in unconsolidated layer is solved effectively. The crawler-type well drilling rig is equipped with drilling machine oil cylinder, and the effect of high explosion pressure on the propulsion and hoisting cylinder and the underground well is realized to achieve the efficiency of drilling footage and high energy consumption.
