SKF PA series hydraulic seals are single-lip seals designed for hydraulic cylinder rods. Their function is to contain the fluid under pressure and prevent the ingress of contaminants, protecting the system and maintaining efficiency. They are used in mobile equipment, presses, agricultural machinery and industry in general. MR Accesorios Industriales supplies this line as an official brand, with technical advice to choose the correct size.

The designation of the PA series is read directly from the code: the letters identify the family and the numbers that follow indicate the dimensions in millimeters. For example, PA 20X30X7X10 corresponds to a seal with a 20 mm inner diameter, 30 mm outer diameter, 7 mm overall height and 10 mm lip height. PA 25X35X7X10, PA 30X40X7X10 and the rest of the available sizes are interpreted in the same way. This nomenclature allows the required part to be identified quickly and without ambiguity.

These seals are used in hydraulic cylinders of road machinery, earthmoving equipment, presses, cranes and agricultural systems. They are also present in the metallurgical, plastics and construction industries, where rods must seal oil at different pressures. In Argentina, they are common in equipment from well-known brands and in cylinder repairs that require reliable sealing to prevent leaks and premature wear.

To select the correct seal, check the rod diameter, the housing diameter and the available height. The PA series allows some tolerance in mounting, but it is essential that the rod surface be ground and free of burrs. Prior lubrication with the same oil as the system makes installation easier and prevents damage to the lip. Also make sure the spring is correctly positioned and that the seal does not sit crooked inside the cavity.

As for equivalents, hydraulic seals are identified by their dimensions and lip type, so they can be interchanged between different brands as long as the dimensions and material match. SKF is a global reference, but there are other alternatives on the market. MR Accesorios Industriales can advise you on the most suitable option for your application, without compromising the performance of the hydraulic system.
