The DBH 8774 is a radial shaft seal that fits into a housing and presses against a rotating shaft. It keeps lubricant in and keeps dust, water, and other contaminants out. Its nominal dimensions are 20.00 mm for the shaft, 32.00 mm for the housing bore, and 4.50 mm for the height. The Lx design means a single lip with a metal case. This seal is a common replacement item in gearboxes, pumps, and electric motors, and it is part of the seals line we supply.
The code 8774 identifies the seal and is the reference you will see on the manufacturer's product page. When you order a replacement, give this code. The Lx design has a single sealing lip and a metal outer case, so it works on rotating shafts that are lubricated. The nominal sizes are shaft 20.00 mm, housing 32.00 mm, and height 4.50 mm.
You will find a seal of this size in small gearboxes, centrifugal pumps, electric motors, reducers, and transmission equipment where a shaft turns inside a housing and oil or grease must stay inside. It also appears in machine tools, washing equipment, and conveying systems. In every case it does two jobs: it holds the lubricant in and blocks contaminants from entering.
Correct installation matters. Make sure the shaft and housing are clean and free of burrs or marks. The shaft surface should have the right hardness and finish for a seal lip. Lubricate the lip before you slide the seal into place, and keep it perpendicular to the shaft. Do not strike it unevenly. If the shaft has play or is worn where the lip contacts it, the seal will not work even if the size is correct. Check the manufacturer's data sheet if you are unsure.
If you need an equivalent, send us the 8774 code along with the shaft, housing, and height dimensions you have. With that information we can look for an alternative in the same DBH line or from other brands we carry. We can also tell you if the Lx design is not right for your application and a different lip or case type is needed.
