A radial shaft seal from the DBH line, the 6893 keeps lubricant where it belongs and keeps dust, water and other particles out. It works on a rotating shaft: the lip rides the shaft while the outer case holds in the housing. The three figures to check are shaft 47.60 mm, housing 69.17 mm and height 8.00 mm, a common metric combination. Treat it as a wear part: once oil starts seeping or grit gets past the lip, it gets swapped out.

The code breaks down simply. The 6893 number is the size reference inside the DBH range, and the Mx designation describes how the seal is built: a metal case with a single sealing lip, made for lubricated rotating shafts. The dimensions listed for this item are shaft 47.60 mm, housing 69.17 mm and height 8.00 mm. Measure both bores before you press anything in, since a few tenths of a millimeter off can lead to a leak or a fit that is too tight.

You will find seals like this in gearboxes, pumps, electric motors, rollers and other transmission equipment where a shaft turns inside a housing holding oil or grease. Agricultural machinery, process lines and material handling systems use them as well. The job is always the same: hold the lubricant in and keep contamination out. In dirty, wet or hot conditions, it pays to look at the seal more often.

Choosing a replacement takes more than three numbers. Lip style, case material and rotation direction all matter, and a torn lip or a weak spring will leak no matter how accurate the dimensions are. When installing, clean the housing first, coat the lip with the same oil or grease the equipment runs, and press the seal in straight rather than at an angle. Any burr or groove on the shaft should be dealt with beforehand, or the new lip will not last long.

If the exact size is not on hand or you need something equivalent, send the code 6893 or the three dimensions. From there we look through the DBH line and other options that could work. A photo of the old seal, the equipment make or the lubricant type helps us answer faster.
