The SKF hydraulic seal of the ZBR-E6W series is a single-lip radial shaft seal with metal reinforcement, designed to be mounted in housings and seal shafts or rods in reciprocating motion. It is manufactured in polyurethane compound that resists hydraulic oils and wear. It is identified by a part number that combines dimensions and compound type. MR Accesorios Industriales supplies this line for industrial applications requiring reliable sealing.

The ZBR-E6W series designation is read as follows: the letters ZBR indicate the SKF hydraulic seal category; next, two numbers separated by an X correspond to the inner diameter and outer diameter in millimeters; after a hyphen, the letter E and a number identify the polyurethane compound; the final W indicates a design variant. For example, ZBR-50X60X7-E6W has a 50 mm inner diameter, 60 mm outer diameter and 7 mm width. ZBR-70X90X13-E6W, ZBR-80X90X7-E6W and ZBR-80X95X10-E6W are interpreted the same way.

These seals are used in hydraulic cylinders, presses, excavators, cranes and earthmoving equipment. In Argentina they are common in the metalworking industry, mining, construction and agriculture, where rods must retain oil and exclude dust. They also appear in lifting machinery and power steering systems. Their single-lip profile makes them suitable for moderate pressures and linear speeds typical of standard cylinders.

To select the seal, verify that the inner diameter, outer diameter and width dimensions match the housing and the rod. The E6W compound is polyurethane, compatible with mineral and synthetic oils, but not with water-based fluids or phosphate esters. During assembly, lubricate the lip with the same system oil, avoid twisting and use burr-free tools. The alignment between rod and housing must be correct to avoid damaging the lip. If the rod shows scratches or wear, correct it before installing the seal.

SKF ZBR-E6W series seals can be interchanged with other single-lip hydraulic seals of equivalent dimensions, provided the compound is compatible with the fluid and working temperature. There is no universal interchange table: each manufacturer uses different part numbers. Therefore, when looking for a replacement, compare diameters, width and elastomer type. MR Accesorios Industriales supplies the SKF brand as part of its seals line, and can advise you if the original part number is not available.
