The DBH 8446 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions —31 mm shaft, 38 mm housing and 5 mm height— make it suitable for compact equipment where axial space is limited. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by part number 8446. Its dimensions are 31 mm shaft diameter (d), 38 mm housing diameter (D) and 5.00 mm height (h). The Ls design corresponds to a seal with a sealing lip and metal case, intended for rotating shafts with lubrication. The 8446 designation is the manufacturer's commercial reference and should be quoted in full when ordering spare parts or equivalents.

Seals of this size are found in small gearboxes, electric motors, centrifugal pumps, compressors, machine tools and transmission equipment. They also appear in applications where oil or grease must be retained while keeping dirt out from the outside. Because of their reduced height, they are common in housings with little axial space or in covers that do not accept wider seals.

To install a radial shaft seal, check that the shaft is clean, free of burrs and marks, and that the sealing surface has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, using a tube or press that bears on the case and not on the lip. If the housing has a shoulder, respect the installation depth. A misaligned or hammered seal loses sealing within a few hours of operation.

If you cannot find part number 8446 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With those three data points we can look for an alternative within the same family or from another brand we supply. It also helps to send a photo of the seal and the housing, or the equipment drawing, to confirm the design and avoid installation errors.
