Product Description

Roof Support Hydraulic Cylinder

Coal mining equipment cylinder has a wide range of applications. Wantong company has been deeply involvedin the field of mining equipment for 15 years, with deep technical expertise and process accumulation, and has achieved full coverage of hydraulic cylinder products for"three machines and one support" equipment (coal shearer, roadheader, scraper conveyor, hydraulic support).

1.Strictly select the procurementchannels, choose high-strength materials, and develop reasonable heat treatment and welding processes to ensure that the cylinderhas extremely high pressure resistance performance under high pressure and heavy load.

2.We have a variety of perfect surface treatment processes,including milky white chromiumthard chromium, tin bronzethardchromium, bronze plating on inner holes, laser cladding ofstainless steel on the inner and outer circles, and melting coppelon inner holes, to meet the different needs of customers.

3.The equipment is complete and the process is perfect, capable of processing products with cylinder diameters ranging from$ 63 to $ 630. it has special processes such as heat treatment, electroplating, and automatic painting lines, and has fullprocess processing capabilities.
