Product Details

Professional manufacturer of hydraulic cylinder barrel, founded in 2004, major in honed tube, hydraulic tube, chrome rod, chrome bar, chrome shaft, at present we are biggest manufacturer and wholesaler in north of China. 


Hydraulic cylinder barrel

Hydraulic cylinder barrel was made by cold-drawn tube and flange, oil port etc. which was precision processed by welded, boring, reaming, skiving or honing. When get through those process barrel can be easy to make into hydraulic cylinder and can be ensure seal ability, reduce abrasion, move smoothly.

Barrel can be produced according to the demands of customers, tolerance as H8, H9. 

According to the pressure requirement and diameter size, different material would be chosen .

Material: DIN2391 standard ST52, EN10305 standard E355, 16Mn, ASTM A106B, C20/20#, CK45

Standard: GB/T8713-88, GB/T3639-2009, DIN2391, EN10305 ASTM A519, DIN2391, EN10204-1
