The DBH 8177 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 93.64 mm shaft diameter, 142.88 mm housing bore and 12.70 mm height place it in medium-to-large equipment. The Mx design combines a main lip with a secondary exclusion lip, which improves performance in dusty or dirty environments. It is press-fitted into the housing and runs on the shaft with slight radial interference.

This item is a radial shaft seal from the DBH brand, identified with part number 8177. Its standard dimensions are 93.64 mm for the shaft diameter (d), 142.88 mm for the housing bore diameter (D) and 12.70 mm total height (h). The Mx design indicates a configuration with a main sealing lip and an auxiliary exclusion lip, mounted on a metal outer ring and an elastic element that ensures contact pressure. The lip elastomer is formulated to resist common industrial oils and greases, although specific chemical compatibility is confirmed against the manufacturer's data sheet.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, mixers, belt conveyors and power transmission equipment in general. In all cases it fulfills the function of closing the passage of lubricant to the outside and preventing the entry of dust, water or particles. It is frequently found on shafts with a diameter close to 94 mm rotating at moderate speeds, where a reliable, low-maintenance barrier is required.

To correctly select a seal, you must verify the shaft diameter, housing bore diameter and height, as well as the type of lubricant and working temperature. Installation is done with the lip lubricated and a tool that presses on the outer ring, never on the lip. Shaft eccentricity and the surface finish of the running track influence service life: a rough or scratched track accelerates wear. If the original equipment comes with a seal of a different design, it is advisable to compare the section and lip type before replacing it.

If you need an equivalent or a nearby size, the most practical thing is to send us part number 8177 along with the measurements taken on the equipment: shaft diameter, housing bore diameter and height. A photo of the old seal showing the markings also helps. With that data we can look for an alternative within the same family or suggest a seal with nearby standard dimensions, always confirming compatibility with the manufacturer.
