SKF hydraulic seals are sealing components mounted in cylinders, pumps and valves to contain pressurized fluid and prevent leaks. In a hydraulic system, a leak not only wastes oil: it lowers working pressure, contaminates the environment and accelerates wear on pumps and valves. That is why the correct seal is chosen by application, not by resemblance. At MR Accesorios Industriales we carry the SKF line and help you identify the code you need.

The codes in this line are numeric, six digits, and do not follow a sequence that can be interpreted at a glance: each number identifies a specific geometry and compound. Therefore, it is not advisable to rely on similarities between nearby codes. The examples we handle are 504262, 504268, 504270 and 504279, but there are many other references within the same family. The safe way to order is with the complete code and, if possible, a photo or sample of the original seal.

These seals are used in hydraulic cylinders of agricultural, road and earthmoving machinery; in presses and equipment in the metallurgical industry; in lifting systems and platforms; and in hydraulic equipment in the food and plastics industries. In Argentina they are commonly found in combine harvesters, sprayers, backhoes and road equipment that work with pressurized oil and demand reliable sealing under dusty and variable temperature conditions.

To properly select a hydraulic seal, you must take into account the working pressure, temperature, fluid and travel speed. The surface finish of the rod or cylinder and the radial clearance also matter: a poorly dimensioned seal gets damaged quickly or does not seal. During assembly, verify that the housing is clean and free of burrs, lubricate the seal with the same system oil and avoid twisting it when inserting. Correct alignment extends the service life of the assembly.

Regarding equivalences, hydraulic seals are identified by code and dimensions, not by brand. The same code may correspond to different manufacturers, but they are not always interchangeable: the compound, lip and tolerance vary. If you do not have the code, we can cross-reference the measurement taken with a caliper and the type of application. Send us the code or measurements via WhatsApp and we will quote it.
