The DBH 8847 radial shaft seal keeps lubricant contained and blocks contaminants from reaching the bearing environment along a rotating shaft. It is pressed into the housing and its lip runs against the shaft. With a shaft size of 156 mm, a housing bore of 180.70 mm and a 12 mm height, this seal fits medium to large rotating equipment where reliable separation between oil and the outside is required.

The seal carries the designation 8847 and belongs to the DBH line. Its three key dimensions are shaft 156 mm, housing 180.70 mm and height 12.00 mm. The Lx design indicates a particular lip and metal case geometry. Before installation, confirm these values on the shaft and housing, since any mismatch in diameter or depth will prevent the seal from seating correctly.

Seals in this size range are common in gearboxes, pumps, mills, mixers and transmission assemblies. They retain oil or grease inside the machine and keep out dust, wash water and moisture. In processing, food and aggregate plants, equipment often runs continuously and is cleaned with water, so effective shaft sealing has a direct effect on bearing service life.

When choosing a replacement, match shaft diameter, housing bore and height to the original. Because the Lx design determines lip and case geometry, substituting a different design without checking compatibility is not recommended. During installation, coat the lip with lubricant, press the seal squarely into the housing and apply force to the outer edge only, never to the lip. Inspect the shaft for burrs or wear marks in the contact zone.

For an equivalent, provide the part number 8847 along with the shaft, housing and height dimensions from the equipment. That information allows us to search for an alternative in the DBH line or among other brands we supply. If the original seal has no readable markings, measure the shaft and housing with a caliper and send those readings so we can narrow the options. We can also review whether a replacement should be evaluated.
