The SKF ZBR-E6W hydraulic seal is a single-lip radial shaft seal with a metal case, intended for sealing rods and shafts that move back and forth in a housing. The lip is made of polyurethane, which stands up to hydraulic oils and wear. Each seal is identified by a part number that encodes its dimensions and compound.

The part number tells you the size and material. ZBR is the SKF hydraulic seal family. Then come two numbers separated by an X: the first is the inner diameter in millimeters, the second the outer diameter. After the hyphen, E6W denotes the polyurethane compound and design variant. For instance, ZBR-50X60X7-E6W has a 50 mm inner diameter, 60 mm outer diameter and 7 mm width. The same reading applies to ZBR-70X90X13-E6W, ZBR-80X90X7-E6W and ZBR-80X95X10-E6W.

These seals are found in hydraulic cylinders, presses, excavators, cranes and earthmoving machines. In metalworking, mining, construction and agriculture, they keep oil in and dust out where rods are exposed. They also appear in lifting equipment and power steering systems. The single-lip profile suits the moderate pressures and linear speeds of standard cylinders.

Selection starts with matching the inner diameter, outer diameter and width to the rod and housing. The E6W compound is polyurethane, compatible with mineral and synthetic oils, but not with water-based fluids or phosphate esters. When installing, lubricate the lip with the system oil, avoid twisting the seal, and use tools free of burrs. Rod and housing must be aligned to prevent lip damage. If the rod is scratched or worn, repair it before fitting the seal.

For replacement, SKF ZBR-E6W seals can be exchanged with other single-lip hydraulic seals of equal dimensions, as long as the compound suits the fluid and operating temperature. No universal interchange table exists because each maker uses its own part numbers. Compare diameters, width and elastomer type instead. MR Industrial Accessories supplies the SKF brand within its seals line.
