This item is a DBH 8621Pol radial shaft seal, identified by its designation 8621Pol. Its main attributes are: shaft diameter (d) of 70 mm, housing bore diameter (D) of 88 mm and height (h) of 8.00 mm. The indicated design is Lx-H-H, which defines the lip and case configuration. It is a sealing component that works on the rotating shaft, with a contacting lip and an outer structure that is fixed in the housing. It is manufactured with elastomers and metal reinforcements according to the manufacturer's series.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, its purpose is to confine the oil or grease and protect bearings and gears from dust, moisture and particles. It is also used in agricultural machinery, process equipment and hydraulic systems where reliable sealing is required on shafts rotating at moderate speeds.

To install this seal correctly, check that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same service oil or grease before inserting it. Insert the seal perpendicularly, without striking the lip, using a suitable installation tube. Selection must consider the peripheral speed of the shaft, the working temperature and the chemical compatibility of the elastomer with the fluid. If the shaft shows wear, consider a seal with an auxiliary lip.
