The DBH 8810 radial shaft seal is a lip seal that mounts between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions —161 mm shaft, 197 mm housing and 12.70 mm height— correspond to medium to large equipment, where the seal works as a continuous dynamic barrier. It is a wear part: when the lip hardens, crystallizes or loses elasticity, oil loss begins and it should be replaced before damage reaches bearings or bushings.

This item is a radial shaft seal from the DBH line, identified with part number 8810. Its nominal dimensions are 161 mm shaft diameter (d), 197 mm housing diameter (D) and 12.70 mm height (h). The indicated design is Mz, a lip configuration that defines how it rests on the shaft and how it seats in the housing. It is a single-section seal, intended for rotating shafts with permanent lubrication and press-fit mounting in the housing.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, mills, mixers, conveyors and process equipment with considerable shaft diameters. In these assemblies, the seal closes the lubricant chamber against the environment: it prevents oil or grease leaks to the outside and blocks the advance of contaminants toward the bearings. It is also used as a secondary closure in equipment with frequent splashing or washing.

To select and install a seal, verify that the shaft diameter and housing diameter match the actual dimensions of the part, not just the drawing. The shaft must be within tolerance, free of burrs or wear marks on the sealing track, and the housing must be clean and free of deformation. The lip is lubricated before installation, inserted perpendicular and seated with the appropriate tool, never with direct blows on the seal. If the shaft shows wear, consider a repair sleeve or a seal with the lip in another position.

If you need a nearby size, a different height or a design other than Mz, the most practical approach is to send the 8810 part number along with the dimensions measured on the equipment. With that data we can look for an equivalent in the same DBH line or in another brand that MR Accesorios Industriales carries, always confirming against the manufacturer's data sheet before closing the purchase. It is also advisable to specify the type of lubricant and the rotation speed to guide the choice properly.

MR Accesorios Industriales carries the DBH brand as part of its seals and oil seals line. If you have doubts about the size, the lip material or compatibility with your equipment's fluid, send the 8810 part number via WhatsApp and we will quote it with the data you need to confirm.
