The DBH 8393Sil radial shaft seal is a lip seal that is mounted in the housing of a fixed component and seals against a rotating shaft. Its function is to retain lubricant inside the assembly and stop the ingress of dust, water or particles that accelerate wear. With 66.68 mm shaft diameter, 89.05 mm housing diameter and 12.70 mm height, it is a replacement size for equipment where axial space is limited and a reliable closure is needed.

This item is a seal with Mx design, with the following dimensions: shaft diameter (d) of 66.68 mm, housing diameter (D) of 89.05 mm and height (h) of 12.70 mm. The Mx design corresponds to a single-lip seal with metal body and elastomeric lip, designed for rotating shafts with permanent lubrication. The designation 8393Sil identifies this specific size within the DBH line. If your equipment requires a seal with these dimensions, this is the direct replacement.

It is used in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where there is a shaft rotating inside a housing and the oil must be separated from the environment. It also appears in old or imported machines where the size is not standard and getting the exact seal avoids modifying the housing or the shaft. It is a wear part: when the lip hardens or the shaft is scored, it starts losing lubricant.

To install it, check that the shaft has no burrs or splines in the sealing area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil as the equipment before inserting it, and apply force on the outer ring, never on the lip. If the shaft shows wear, consider a repair sleeve or a nearby size. Selection depends on speed, temperature and the type of fluid; with that data the lip compound is confirmed.

If you cannot find the exact size or need an equivalent, send us the part number 8393Sil or the shaft, housing and height dimensions. We can also look for a nearby size within the DBH line or from another brand that MR supplies. The more data you provide —equipment, position, fluid and temperature— the faster we can bring you the correct option.
