Oil Cylinder

The company is committed to manufacturing high-end anti-corrosion pure water hydraulic support columns and jacks, with 30 years of research and development, design, production and sales experience, and widely serves hydraulic support manufacturers nationwide. At present, it has developed into one of the largest coal engine oil cylinder production bases in China, with an annual production capacity of 24000 tons, 200000 pieces, and an annual output value of 500 million yuan. Product specifications from φ 63mm to φ530mm. There are a total of more than 50 types (oil red inner diameter division of this specification), all of which have passed the testing and inspection of the National Mining Product Safety Mark Center. Besides, our company has obtained relevant qualifications such as safety mark certificates, and has various surface treatment capabilities such as copper melting, flame support, copper plating, engraving, PIP, etc., and can meet the needs of different customers.  Cylinder  Diam.(mm)Column Diam.(mm)Initial Support Force(Kn) (P=31.5Mpa)Column Lowering Force(Kn) (P=3l.5Mpa)φ140/φ100φI30 /φ85primary cylinder:237.4 primary cylinder: 66. 7Secondary cylinder:247.3 secondary cylinder: 68.7φ160/φ125φ150/φ105primary cylinder:246.6primary cylinder:76.6secondary cylinder:386.4secondary cylinder: 113.8φ180/φ140φ170/φ120primary cylinder:316.6primary cylinder:86.4secondary cylinder:484.7secondary cylinder:128.7φ200/φ340φ185/φ130primary cylinder:504.5primary cylinder:142.8secondary cylinder: 484.6secondary cylinder:66.8φ280/φ200φ260/φ185primary cylinder:949.5primary cylinder:267secondary cylinder: 989. 1secondary cylinder: 142.8φ300/φ220φ280/φ19primary cylinder:1028.7primary cylinder:286.8secondary cylinder:1196.8secondary cylinder: 256.5φ320/φ230φ290/φ210primary cylinder:1224primary cylinder:452.7secondary cylinder: 1308. 7secondary cylinder: 217.7φ360/φ270φ340/φ230primary cylinder:1402.1primary cylinder:346. 2secondary cylinder:1802.6secondary cylinder: 494.5φ380/φ280φ360/φ260primary cylinder: 1632primary cylinder:366secondary cylinder: 1938.6secondary cylinder: 267φ400/φ300φ380/φ260primary cylinder:1730.9primary cylinder: 385. 7secondary cylinder: 2225.5secondary cylinder:553.9φ420/φ290φ390/φ260primary cylinder:2282.3primary cylinder:600.9secondary cylinder:2079.6secondary cylinder: 408φ440/φ330Φ420/ φ300primary cylinder:2094.4primary cylinder:425.3secondary cylinder: 2692.8secondary cylinder: 467.4φ460/φ350φ440/φ310primary cylinder: 2203.2primary cylinder: 445. 1secondary cylinder: 3029. 1secondary cylinder:652.8Φ480/φ360φ455/φ310primary cylinder:2492.5primary cylinder:578secondary cylinder:3204.7secondary cylinder: 828.4φ500/φ360φ475/φ335primary cylinder: 2977.2primary cylinder: 602.7secondary cylinder: 3204. 7secondary cylinder: 429.6φ530/φ380φ500/φ355primary cylinder:3375.3primary cylinder:764.1secondary cylinder: 3570.6secondary cylinder: 454.4/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
