Sealing a rotating shaft comes down to matching the seal to the space it sits in, and the DBH 8040Pol is built for a shaft of 75 mm, a housing bore of 90 mm and a height of 10 mm. It is a radial shaft seal of the Lx design, a single lip with a spring, so it holds lubricant on one side and keeps dust, water and particles out on the other. MR Industrial Accessories supplies this line and helps you confirm the right choice before you install.

The code tells you most of what you need. DBH identifies the seal family, 8040Pol points to the size and construction within that family, and Lx describes the lip arrangement: one lip, spring loaded, made for rotating shafts that run with lubrication. Read the dimensions in the same order every time, shaft 75 mm, housing 90 mm, height 10 mm, and check them against the bore and shaft on your unit before ordering.

Typical homes for this seal are gearboxes, pumps, electric motors, rollers and other transmission equipment where a shaft turns inside a housing and oil or grease has to stay put. In dirty or wet surroundings the lip also works as a barrier against contamination. Treat it as a wear part: the lip eventually hardens or scores, and that shows up as a leak or as grit working its way in. Either sign means it is time to replace it.

Size alone is not the whole selection. Shaft speed, operating temperature and the lubricant in use all affect how the seal performs, and the Lx design with its spring suits continuously lubricated rotating shafts. At installation, coat the lip with lubricant, make sure the shaft is free of burrs and marks and the housing is clean, and press the seal in square without hammering the lip out of shape. If the shaft surface is worn, a seal that positions the lip on a fresh area of the shaft is worth considering.

For an equivalent, send the 8040Pol code or simply the three dimensions of the seal you are running. With that we can look at options in the DBH line or in other brands we supply, and we can tell you whether the Lx design fits your case or whether another lip configuration makes more sense.
