The DBH 6759Sil is a radial shaft seal that sits in the housing and works against the rotating shaft, holding lubricant in and keeping dust, water and particles out. Its size matches a common standard: shaft 57.15 mm, housing 76.20 mm, height 9.50 mm. You will find it on pumps, electric motors, gear reducers and other power transmission equipment, both for replacement work and for building new assemblies.

Read the code and the numbers together. The 6759Sil reference places the part inside the DBH line, while the three figures describe the fit: 57.15 mm at the shaft, 76.20 mm at the housing bore and 9.50 mm of height. This is an Mx design, a single-lip seal built with a metal case and elastomer for rotating shafts that run with permanent lubrication. Having the full designation on hand makes ordering straightforward and leaves no room for confusion.

In service, the seal does two jobs at once. It stops oil or grease from escaping the housing and it blocks outside contaminants from reaching the bearing or gear set. That is why it shows up in gearboxes, centrifugal pumps, electric motors, drive shafts and continuous process equipment. Treat it as a wear part: replace it when you see lubricant loss, or when the shaft raceway shows play or roughness.

Installation rewards a little care. The housing and shaft should be clean and free of burrs or deep marks, and the lip needs lubrication before it goes in. Press the seal in perpendicular to the shaft and avoid striking the elastomer directly; a tube or shim that bears on the outer diameter works well. If the shaft contact area is worn, you can shift the seal position slightly or fit a repair sleeve.

Looking for an equivalent? Send the code 6759Sil along with the shaft, housing and height dimensions and describe the application. With that information we can search for an alternative in the same DBH line or in another brand we supply. We can also tell you whether the mounting space accepts a different height, or whether a design with an extra lip suits a dirtier environment better.
