SKF DSW hydraulic seals are sealing components for hydraulic cylinder rods. Their design combines a sealing lip and a wiper element that prevents particles, water or dust from entering the system. They are used in mobile equipment, presses, construction machinery and industrial systems that work with hydraulic oil. MR Accesorios Industriales supplies this line with technical advice to choose the right size and compound.

The DSW-…-J…G designation is read as follows: DSW identifies the category of SKF hydraulic seals for rods; the first number indicates the nominal rod diameter in hundredths of an inch or millimeters depending on the series; J indicates the single-lip profile; the number after the J corresponds to the height or section group; and the final G indicates the general-purpose nitrile rubber (NBR) compound. For example, DSW-625-J2G and DSW-1000-J2G share the same J2G profile but differ in diameter. Always verify the complete part number on the drawing or on the original part.

These seals are used in hydraulic cylinders of excavators, backhoe loaders, cranes, presses, earthmoving equipment, power steering systems and agricultural machinery. In Argentina, the sectors that demand them most are construction, mining, the oilseed industry and heavy metalworking. They are also used in lifting equipment and in marine cylinders. Exposure to mud, dust and temperature variations means the seal must resist abrasion and maintain sealing in every cycle.

To select the correct seal, take into account the rod diameter, the housing outer diameter, the cavity height and the type of hydraulic fluid. The NBR compound of the DSW line is compatible with mineral oils and greases, but not with phosphate ester-based or biodegradable ester fluids, where a different elastomer is required. During assembly, verify that the lip is not inverted, lubricate with the same oil as the system and make sure the rod surface has no burrs or scratches. Poor alignment or excessive clearance shortens seal life.

Regarding equivalents, SKF DSW seals can replace other hydraulic seals of similar profile from different brands, but interchangeability is not automatic: diameters, height, lip type and compound must be compared. It is not enough for the nominal size to match. Send a photo of the part and the housing dimensions. At MR Accesorios Industriales we help you identify the correct alternative within the SKF line we supply.
