Part 8189 from the DBH line is a radial shaft seal that keeps oil or grease inside the space between a turning shaft and its bore. It fits a shaft of 24 mm, a housing of 47 mm and a height of 10 mm, and it carries the Lx designation. Units like this are pressed into covers, crankcases and gear housings, and MR Industrial Accessories supplies this brand and helps buyers match the right seal to the job.

Reading the code first: the three figures 24 x 47 x 10 mm follow the usual order for this family of seals, shaft diameter (d), housing bore (D) and height (h). The Lx designation tells you the geometry: one sealing lip with a spring, and no second lip on the outside for dust. The elastomer lip rides on the shaft and holds a light radial load, which is what produces the seal both while the shaft turns and while it stands still.

Typical homes for this seal are electric motors, centrifugal pumps, gear reducers, gearboxes, compressors and power transmission equipment. Off-highway equipment also uses it, where its job is to keep bearings and gears clear of contamination and to stop lubricant from escaping. Treat it as a wear item. Whenever the machine is opened up, look at the lip: a hardened edge, nicks or a lip that has lost its springiness mean it is time for a new one.

Installation decides how long the seal lasts. The shaft should be free of burrs and grooves, and the bore clean with no dents. Coat the lip with the same oil or grease the equipment runs on, then drive the seal in with a flat tube so it goes in square. Shaft runout and bearing clearance have to sit inside tolerance, or the lip cannot do its work. If the seal you are removing has a dust lip, choose an equivalent that has one too.
