SKF G series hydraulic seals are sealing elements designed to retain oil or grease in hydraulic and pneumatic components. They are manufactured with high-resistance elastomers and are mounted in cylindrical housings to prevent leaks and the entry of contaminants. MR Accesorios Industriales sells this line for maintenance of cylinders, pumps and valves in Argentine industry.

The G series designation is read as G followed by the nominal measurements: inner diameter, outer diameter and height, expressed in millimeters. For example, G 8X12X3 indicates a seal with 8 mm inner diameter, 12 mm outer diameter and 3 mm height. Similarly, G 20X28X4 corresponds to 20 mm inner, 28 mm outer and 4 mm height. This nomenclature allows quick identification of the size without the need for an additional catalog.

These seals are used in hydraulic cylinders, presses, positive displacement pumps, directional valves and pneumatic systems. Industries such as metalworking, food processing, mining and agriculture use them to repair equipment and maintain working pressure. In Argentina, they are common in road machinery, cranes and earthmoving equipment, where sealing reliability is critical to avoid unscheduled downtime.

To select the appropriate seal, verify the housing dimensions and the type of fluid. The G series accepts mineral and synthetic oils, and its elastomer resists moderate temperatures. During mounting, ensure alignment of the rod or piston, lubricate the lip with the same working fluid and avoid damaging the sealing edge. Excessive axial clearance or a worn housing can cause premature leaks.

Regarding equivalences, SKF G series seals can be interchanged with products from other brands that follow the same dimensional designation and the same profile. Always compare the elastomer material and the temperature range before replacing. Interchangeability depends on the measurements and the application matching exactly.
