The DBH 8445 is a radial shaft seal built for rotating equipment, where it keeps oil or grease in and keeps dust and water out. Its Kx design pairs a main sealing lip with a secondary dust lip, so it holds up in dirty surroundings. The seal presses into the housing and runs against the shaft, with a shaft diameter of 125 mm, a housing diameter of 152.40 mm and a height of 15.00 mm.

Part number 8445 comes from the DBH line of radial shaft seals. The three figures to match on any replacement are shaft diameter (d) 125 mm, housing diameter (D) 152.40 mm and height (h) 15.00 mm. The Kx designation tells you the seal has two lips: one retains lubricant, the other excludes outside contamination. A metal outer case holds the seal firmly in the housing bore, while the sealing lip is normally an elastomer chosen for oil and temperature resistance.

Seals in this size range turn up in gearboxes, pumps, electric motors, drive shafts and process equipment that runs continuously. They suit assemblies where the shaft turns at moderate to high speeds and where losing lubricant or letting particles in would cause problems. They are also a practical answer for older or hard-to-reach machines, where getting the exact replacement right the first time avoids a long shutdown.

Before installing, inspect the shaft for burrs or wear in the lip contact area and make sure the housing bore is clean and not deformed. Coat the lip with the same oil or grease used in the equipment, then seat the seal square to the shaft and press evenly on the outer ring. If the shaft has a pronounced groove, you can set the seal slightly offset or fit a wear sleeve. The Kx design is the right pick when dust or water ingress is a concern.
