CD/CG250、CD/CG350系列重载液压缸
本系列缸是由14种缸径，分别按四种速比组成28种规格的单活塞双作用差动油缸。另缸头法兰式、中间耳轴安装式和底座安装式三种还可做成双活塞杆双作用等速油缸，再加上无端部缓冲和两端部有缓冲与上述28 种规格组成384 个品种。特别适合于环境恶劣、重载的工作状态下，广泛应用于钢铁、铸造、锻造及机械制造等工业部门。
The CD series cylinders is a single-piston double-acting differential cylinder of 28 specifications composed of 14 cylinder diameters and four speed ratios respectively. In addition, the three types of cylinder head flange type, intermediate trunnion installation type and base installation type can also be made into double piston rod double acting constant velocity cylinder, plus no end buffer and buffer at both ends, and the above 28 specifications are composed of 384 species. It is especially suitable for harsh environments and heavy-duty working conditions, and is widely used in steel, casting, forging and machinery manufacturing and other industrial sectors.
