When a rotating shaft needs reliable separation between lubricant and the outside environment, the DBH 8843 radial shaft seal is the part that does the job. It fits a 170 mm shaft, a 210 mm housing bore and a 15.00 mm cavity height, dimensions that point to large gearboxes, heavy pumps and similar equipment. MR Industrial Accessories LLC supplies this line and works with you to confirm the correct seal for the application.

The code 8843 belongs to the DBH line of radial shaft seals. Reading the designation: 170 mm is the shaft diameter (d), 210 mm is the housing diameter (D) and 15.00 mm is the height (h). The Lz version combines a sealing lip with a dust lip, so it holds lubricant in and keeps external particles out in dirty or dusty surroundings. Installation is by press fit into the housing, with the lip running against the shaft.

Sizes like this show up in high-power gearboxes, mills, process centrifugal pumps, mining machinery and large agricultural equipment. In each case the seal keeps oil or grease where it belongs and shields bearings and gears from water, dust and metal particles that would otherwise speed up wear.

Before ordering, confirm that the shaft and housing dimensions match the values above. Lubricate the lip before pressing the seal in, and check the shaft for burrs or wear that could cut the lip. The 15.00 mm height tells you how much room the cavity offers; a different housing depth means looking at another size. Shaft speed, operating temperature and the fluid being sealed also affect the choice of lip material.

If you need a replacement for the 8843, send the code plus the shaft, housing and height measurements, along with a photo or sample of the old seal. Our team checks equivalents in the same brand or in other lines we carry and confirms which option fits. We can also tell you whether the Lz design is the right one for your setup.
