Plunger hydraulic cylinder features

(1) The plunger type hydraulic cylinder is a single-acting hydraulic cylinder, which can only achieve movement in one direction by hydraulic pressure. The return stroke of the plunger depends on other external forces or the weight of the plunger;

(2) The plunger is supported only by the cylinder sleeve and is not in contact with the cylinder sleeve, so that the cylinder sleeve is extremely easy to process, so it is suitable for a long stroke hydraulic cylinder;

(3) The plunger is always under pressure during operation, so it must have sufficient rigidity;

(4) The weight of the plunger tends to be large. When it is placed horizontally, it is easy to sag due to its own weight, causing the seal and the guide to wear on one side, so it is more advantageous for vertical use.
