The DBH 8478 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering equipment with a rotating shaft. Due to its dimensions of 145 mm shaft, 175 mm housing and 13 mm height, it is installed in gearboxes, pumps and medium-to-large reducers. MR Accesorios Industriales sells this brand and advises you so you choose the correct seal for your application.
This item is a DBH radial shaft seal identified by part number 8478. Its dimensions are 145 mm shaft diameter, 175 mm housing diameter and 13.00 mm height. The Kx-Bidi design corresponds to a double-lip configuration with reinforcement, intended to contain lubricant from both sides of the seal. The elastomer and internal spring work on the shaft to maintain contact and compensate for small misalignments.
Seals of this size are used in equipment where the shaft rotates at moderate speeds and oil or grease is present. They are commonly found in gearboxes, centrifugal pumps, mixers, mills and conveyors. They are also installed in large electric motors and in old machines where the housing already has wear from use. In all cases, the function is the same: retain lubricant and block dust.
To select the correct seal, verify that the shaft diameter, housing diameter and height match those of the DBH 8478. Check the condition of the shaft surface: if it has a groove or deep scratches, the lip will not seal properly and it is advisable to repair it or use a sleeve. During installation, lubricate the lip with the same grease or oil as the equipment and press the seal evenly, without tilting it. If the housing has burrs, clean before inserting it.
If you need a nearby size or an equivalent from another brand, send us the full part number and the dimensions of the old seal. A photo of the part and the housing also helps. With that data we look for alternatives within the DBH line or from other brands we sell. We do not invent dimensions: we confirm against the manufacturer's data sheet before quoting. That way you avoid buying a seal that does not fit.
