The DBH 8179 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and stop the entry of dust, water or particles. Its dimensions are 95 mm shaft diameter, 130 mm housing diameter and 12 mm height, with Mx design. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and helps you confirm the size before quoting.

This item is a radial shaft seal from the DBH line, identified by part number 8179. It runs on a shaft of 95 mm diameter and fits into a bore of 130 mm; its overall height is 12.00 mm. The Mx design corresponds to the construction with sealing lip and metal body, intended for rotating shafts with lubrication. The lip bears on the shaft and creates the dynamic seal; the outer body remains fixed in the housing. It is a wear part: when the lip hardens, crystallizes or loses elasticity, oil leakage begins to appear.

Typical applications for a seal of this size are in equipment with medium-diameter transmission shafts: gearboxes, reducers, centrifugal pumps, electric motors, rollers and mixers. It is also found in machine tools and process equipment where the lubricated side must be separated from the environment. In all these cases it performs two functions at once: retaining the lubricant inside the assembly and preventing contaminants from entering from outside, which extends the life of bearings and gears.

To install a seal, check the condition of the shaft surface: it must be smooth, without grooves or burrs, because any mark on the sealing track accelerates lip wear. Lubricate the lip before inserting it and use a tube or press that bears on the outer edge, never on the lip. The shaft, housing and height dimensions must match those of the original housing; if in doubt, compare against the manufacturer's data sheet. Also check that the housing has no play or deformation.

To quote the 8179, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With those three data points we look for the equivalent in the same brand or in another line we carry. We also confirm whether the Mx design is right for your application or whether another lip variant is better suited. The more complete the equipment information, the faster the response.

To request a quote for the DBH 8179 oil seal, write to us on WhatsApp and send us the part number or the dimensions. MR Accesorios Industriales carries this brand and has experience in bearings, power transmission and seals, so we can also advise you on installation or selecting a replacement. If the seal goes inside an assembly, it is worth checking the condition of the bearings and the shaft before closing it up.
