The DBH 8168 radial shaft seal is a lip seal that blocks the passage of oil or grease at the point where a shaft passes through a housing, while also preventing the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a fixed body. Its A 135 design combines a sealing lip with a metal case that is press-fitted into the housing.

This item is identified by part number 8168 and follows the A 135 design. Its dimensions are 24.50 mm shaft diameter, 47.00 mm housing diameter and a height of 7.00/11.00 mm, meaning the profile has two heights: the smaller one corresponds to the seat inside the housing and the larger one to the lip that runs on the shaft. This difference in height is common in seals with an additional protective lip against contaminants.

Typical applications for a seal of this size appear in equipment with small-section shafts and moderate speeds: gearboxes, electric motors, centrifugal pumps, compressors, machine tools and belt or chain drives. It is also found in agricultural implements and process equipment where lubricant must be retained and washdown or ambient dust kept out.

To select and install a radial shaft seal, three things should be checked: that the shaft diameter is within the recommended tolerance and free of marks or burrs, that the housing has the correct diameter and depth, and that the lip is lubricated before assembly. The seal is inserted perpendicular, with a press or a support tube on the outer edge, never by striking the lip. If the shaft shows wear, consider a repair sleeve.

If you need an equivalent or the same seal in another brand, send us part number 8168 along with the shaft, housing and height dimensions. With that data we can cross-reference the designation, the A 135 design and the dimensions to offer you a compatible alternative. We can also check whether the housing accepts a seal of a different height within the same category.
