A radial shaft seal from the DBH line, identified by code 5548. It carries a single sealing lip on a metal case, the Mt design, and its nominal measurements are 49.5 mm at the shaft, 66.6 mm at the housing and 6.35 mm in height. MR Industrial Accessories supplies this brand and can verify the size with you before you place a request.

How the seal works: the outer case presses into the housing bore and stays put, while the lip rides on the rotating shaft. That split of duties is what holds grease or oil inside the assembly and keeps dust, water and particles out. The Mt designation tells you it is a single-lip seal with a metal body, built for rotating shafts that run with permanent lubrication.

Where it fits: gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment are the usual homes for a seal this size. You will also find it on conveyors, agricultural machinery and plant equipment exposed to dust or moisture. The job does not change from one machine to the next: lubricant stays in, contaminants stay out, and bearings and gears last longer as a result.

Reading the code and checking the fit: 5548 is the reference to quote, and the three figures that matter are shaft 49.5 mm, housing 66.6 mm and height 6.35 mm. Match all three against the old seal or against the bore and shaft with a caliper. Look at the running surface too, because a scored or worn shaft will not seal properly no matter how accurate the size is.

Installation notes: coat the lip with the lubricant already used in the assembly, set the seal square to the bore and drive it in with a tube or sleeve sized to the outer case. Striking the lip directly damages it. If the equipment runs hot or fast, ask about the lip compound before you commit to a reference.

Need a match or an alternative: send code 5548, or the shaft, housing and height you measured, through WhatsApp or email. We check the DBH line and the options that suit the application, and we flag it when the original seal uses a different lip geometry or material. The more detail you give us about the equipment, the closer the first proposal will be.

Quotes are handled by part number: message us with 5548 and the quantity required. If the size is in doubt, a photo of the removed seal or caliper readings are enough for us to check it with you.
