SKF hydraulic seals of the GH series are sealing elements designed for hydraulic cylinder rods. Their function is to retain fluid inside the system and prevent contaminants from entering, working under pressure. They are manufactured with a profile that combines a sealing lip and an energizing ring that ensures constant contact. They are suitable for industrial and mobile applications where reliability and low friction are required.

The GH series designation is interpreted from the full part number. For example, GH 25X17.5X3.2-AD1 indicates a rod seal with an inner diameter of 25 mm, an outer diameter of 17.5 mm and a height of 3.2 mm. The suffix -AD1 identifies the compound and lip design variant. Other examples such as GH 80X64.5X6.3-AD1 show that the series covers a range of sizes, always with the same logic: the letters GH define the family and the numbers the dimensions. The AD1 suffix is common in this series and refers to the elastomer formulation.

These seals are used in hydraulic cylinders of agricultural machinery, road equipment, presses, cranes and lifting systems. In Argentina, they are common in combine harvesters, tractors, backhoe loaders and earthmoving equipment, where dust and weather demand robust sealing. They are also used in steering and suspension cylinders of heavy vehicles. The GH series performs well in applications with moderate pressures and linear speeds typical of these systems.

To select the correct seal, take into account the housing and rod dimensions, the hydraulic fluid and the operating conditions. Verify that the inner diameter matches the rod and that the height is compatible with the groove. During assembly, lubricate the lip with the same system oil, avoid twisting and make sure the rod has no burrs. Cylinder alignment and rod surface condition directly influence seal service life.

Regarding equivalences, hydraulic seals are identified by their dimensions and profile. When looking for a replacement, compare diameters and height, and consider the type of compound. The SKF GH series can be interchanged with other seals of similar characteristics, but always verify chemical compatibility with the fluid and the pressure and temperature conditions. Do not invent part numbers: be guided by the actual housing dimensions.
