Description

CD250/CG250 CD350/CG350 series heavy-duty hydraulic cylinder

This series of cylinders consists of 14 kinds of cylinder diameters, which are composed of 28 kinds of single-piston double-acting differential cylinders according to four speed ratios.In addition, the cylinder head flange type, the middle trunnion mounting type and the base mounting type can also be made into a double piston double acting constant speed cylinder, plus an endless buffer and buffer at both ends (using an adjustable flow valve) and the above 28 specifications constitute 384 varieties.

This series of products is installed in accordance with German standards and ISO3320. It is especially suitable for industrial sectors such as steel, casting and machinery manufacturing under harsh and heavy-duty conditions.

Note: According to Euler's formula, the safety factor of the rod under the hinged structure and rigid guiding load is 3.5. For various installation types and various cylinder diameters under different working pressures, the piston rod is under bending stress ,(compression load).Allowable stroke under action , see the sample for details.
