For rotating shafts that need dependable lubricant retention, the DBH 9819 oil seal is a single-lip radial shaft seal. It fits a 78 mm shaft, a 115 mm housing bore and has a height of 10.00/19.00 mm. The design combines a sealing lip with a metal case for press fitting into a cylindrical housing. The stepped 10/19 mm height accommodates an auxiliary lip or shoulder section. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

The designation 9819 identifies a DBH radial shaft seal with an A 309 style: a sealing lip and a metal outer case that presses into a cylindrical housing. Its three critical dimensions are shaft diameter (d) 78 mm, housing diameter (D) 115 mm and overall height (h) 10.00/19.00 mm. The dual height figure indicates a stepped or double-lip construction that adds a secondary sealing edge.

Seals in this series suit continuous rotation where oil or grease must stay in and contaminants must stay out. Typical equipment includes gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission drives. In agricultural and road machinery, the same sealing principle protects bearings from dust and moisture.

Selection starts with confirming shaft and housing dimensions against the equipment. Peripheral speed, operating temperature and lubricant type all affect the choice of lip material. On installation, apply lubricant to the lip, keep sharp edges away from the sealing surface and verify the housing is clean and free of burrs. These steps help the seal reach its expected service life.
