SKF ZW series hydraulic seals are lip seals designed to be mounted on hydraulic cylinder rods. Their function is to contain pressurized fluid and prevent leaks, as well as to stop contaminants from entering. They are available in standard sizes, with inner and outer diameters ranging from 25x32 to 45x55, among other variants. They are wear parts that should be replaced when leaks appear or the lip hardens.

The ZW series designation is read as ZW followed by two dimensions separated by an X: the inner diameter and the outer diameter. For example, ZW 25X32 corresponds to a seal with a 25 mm inner diameter and a 32 mm outer diameter. Any suffixes that may appear after the dimensions indicate material or lip configuration variants, but in this series the part numbers are identified mainly by that combination of diameters. To choose the right one, always compare the full part number with the housing and rod dimensions.

These seals are used in hydraulic cylinders of agricultural machinery, road equipment, presses, forklifts and lifting systems. They are also found in the metallurgical, plastics and earthmoving industries, where rods work with pressurized oil and are exposed to dust or water. In Argentina, they are commonly found in agricultural implements and construction equipment operating in severe conditions. MR Accesorios Industriales carries this line for replacement and maintenance.

To select the seal, check that the inner diameter matches the rod and the outer diameter matches the housing. The width and shape of the lip must correspond to the original design. During assembly, lubricate the lip with the same oil used in the system, avoid impacts and make sure the rod has no burrs. Cylinder alignment and the condition of the rod surface affect service life. If the rod is pitted or worn, the new seal will not seal properly.

As for equivalents, hydraulic seals are identified by their standard sizes, so different brands offer products with similar dimensions. What matters is respecting the size and the lip type. Not all brands use the same nomenclature, so it is best to go by the millimeters. If you have doubts, send us the part number engraved on the old part or the dimensions measured with a caliper. At MR we advise you so the replacement is the right one.

To request a quote, send the full seal part number by WhatsApp, for example ZW 30X37, or the rod and housing dimensions. With that data we will send you the quote and the alternatives. We work with recognized brands and also with in-house manufacturing in other areas, always aiming to get your equipment running again without delays.
