Part number 8446 belongs to the DBH line of radial shaft seals. It sits between a turning shaft and a stationary housing, holding lubricant in and keeping dust, water and particles out. Shaft 31 mm, housing 38 mm, height 5.00 mm — a small cross-section that fits assemblies where there is little room along the axis. MR Industrial Accessories LLC supplies this brand and can help you match the seal to the job.

The code breaks down simply: 8446 is the reference the maker uses for this size, and Ls tells you what kind of seal it is — a metal case with a sealing lip, made for rotating shafts that run lubricated. When you order spares or ask for a substitute, give the full reference so nothing gets mixed up with a similar number.

Seals in this size range turn up in small gearboxes, electric motors, centrifugal pumps, compressors, machine tools and transmission units. They are also used wherever grease or oil has to stay inside while dirt stays outside. The low 5.00 mm height is the reason they appear in shallow housings and in covers that will not take a taller seal.

Fitting one takes a few precautions. The shaft should be clean, with no burrs, nicks or handling marks, and the sealing surface should have the right roughness. Put a little lubricant on the lip before you slide it in, then press it in square to the shaft using a tube or press that pushes on the metal case, never on the lip. Where the housing has a shoulder, seat the seal to the depth called for. A seal that goes in crooked or gets tapped with a hammer will start leaking within hours of running.

For a quote on 8446, send the three dimensions of the seal you are replacing: shaft diameter, housing diameter and height. With those numbers we can check for an alternative in the same family or from another brand we carry. A photo of the seal and the housing, or the drawing of the equipment, also helps confirm the design and avoid a wrong fit.
