When a shaft seal starts weeping, the replacement needs to match the bore and the shaft exactly. The DBH 8009Pol is a single-lip radial shaft seal with a spring, built for rotating shafts where lubricant has to stay in and contaminants have to stay out. MR Industrial Accessories supplies this brand and helps maintenance teams confirm the right seal before they install it.

The 8009Pol carries the Mx-R designation, which identifies a single sealing lip with a spring. Its dimensions are shaft 79 mm, housing 95.25 mm and width 11.11 mm. Those three figures are what you compare against the worn part and the housing bore: if any one of them is off, the seal will not seat or seal correctly. DBH is a brand we supply, so alternatives in the same size range can be reviewed if needed.

Seals of this type show up in gearboxes, pumps, electric motors, rollers and other power transmission equipment. Two jobs are performed at once: oil or grease is held inside the housing, and dust, water and particles are kept out. Where vibration or moderate temperatures are present, the spring keeps the lip pressed against the shaft, which helps the assembly reach its expected service life.

Installation decides how long the seal lasts. The shaft surface should have the specified hardness and roughness, free of burrs, scratches or a worn groove under the old lip. Apply lubricant to the lip before fitting, and press the seal in with a tool that contacts the outer diameter only, never the lip. If the housing bore is worn or scored, a taller seal or a wear sleeve is worth considering. Shaft and housing must also be aligned, since misalignment is a common cause of early leakage.

To find an equivalent, send the complete part number, the shaft, housing and width dimensions, and a photo of the removed seal. With those details we can search our line of seals and oil seals for a match. If the Mx-R profile is not the best fit for your equipment, we can also point you toward a different lip configuration.
