The DBH 5639 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing, while at the same time preventing dust, water or particles from entering from the outside. It is mounted in gearboxes, pumps, motors and transmission equipment where lubricant must be retained on a 38.10 mm shaft. Its A 006 design and stepped height of 12.00/14.00 mm place it in continuous-duty applications with moderate demands.

This item is identified by DBH code 5639 and corresponds to design A 006. Its dimensions are shaft (d) 38.1 mm, housing (D) 57.94 mm and height (h) 12.00/14.00 mm, meaning the sealing lip bears on a 38.10 mm shaft and the 57.94 mm outer diameter is press-fitted into the housing. The double height indicates a body with a stepped section, covering both mounting dimensions depending on how the part is seated.

Typical applications for a seal of this size appear in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all these cases the seal performs two functions at once: it retains the lubricant inside the assembly and blocks the ingress of contaminants along the shaft. It is also used as a secondary closure in bearings and bushings mounted on 38.10 mm shafts.

To select it properly, verify that the shaft and housing diameters match the values on the product page, that the shaft has no burrs or marks in the lip contact area, and that the sealing surface is lubricated before mounting. The seal is inserted perpendicular to the shaft, without striking the lip, and it is advisable to check the internal spring and the condition of the housing before replacing it.

If you need an equivalent from another brand, send us code 5639 or the shaft, housing and height dimensions. With that data we can locate the alternative that best fits your equipment. If the original seal has no legible identification, a photo or a caliper reading on the shaft and housing also works.
