A rotating shaft passing through a housing needs a barrier at that point, and the DBH 8101 radial shaft seal is built for exactly that job. It keeps lubricant where it belongs and keeps dust, water and particles out. The Mx design, together with a 120 mm shaft, 140 mm housing and 13 mm height, places it in gearboxes, pumps, motors and transmission equipment that run shafts of that diameter. MR Industrial Accessories supplies this brand.

Reading the designation is straightforward. The number 8101 identifies the seal, and the three figures that follow describe the fit: shaft 120 mm, housing 140 mm, height 13.00 mm. The Mx design covers the lip geometry and the metal body, so it suits housings built to that configuration. When you compare a replacement against the part coming out of the machine, the shaft figure tells you how the lip will sit and the housing figure tells you how the outer body will hold in the bore. Both need to line up before you order.

Seals in this size range turn up on medium-section transmission shafts. Gearboxes, centrifugal pumps, electric motors, mixers and rollers are common examples. The duty is always the same: hold oil or grease in the assembly and block contaminants that would otherwise shorten the life of bearings and gears. In areas with splashing liquid or airborne dust, the same seal often acts as a secondary barrier.

Shaft condition matters as much as the dimensions. A fresh lip will not seal properly against a scored or worn track, so inspect that surface first. If a groove is present, setting the seal at a slight axial offset is one option, and a wear sleeve is another. Check the housing bore, the entry chamfer and the lip lubrication before the shaft goes back in. The Mx design and the three dimensions are what define the part.

Send the measured dimensions or the old code and we will search the DBH line for you. An equivalent from another brand with matching shaft, housing and height dimensions can also be reviewed. The more detail you send, the quicker the quote comes together.
