The DBH 8774 radial shaft seal is a lip seal that is mounted in the housing and closes against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With dimensions of 20 mm shaft, 32 mm housing and 4.50 mm height, and Lx design, it is a common replacement part in gearboxes, pumps and electric motors. MR Accesorios Industriales carries it within its seals line.

This item is a radial shaft seal of the DBH brand, identified with the code 8774. Its nominal dimensions are 20.00 mm shaft diameter (d), 32.00 mm housing diameter (D) and 4.50 mm height (h). The Lx design corresponds to a single-lip seal with a metal case and sealing lip, intended for rotating shafts with lubrication. The 8774 designation is the reference you will find on the manufacturer's product page and the one you should cite when ordering a replacement.

Typical applications for a seal of this size include small gearboxes, centrifugal pumps, electric motors, reducers and transmission equipment where there is a shaft rotating inside a housing and the oil or grease needs to be contained. It is also used in machine tools, washing equipment and conveying systems. In all cases it performs two functions: retaining the lubricant inward and preventing contaminants from entering from outside.

To install it properly, check that the shaft and housing are clean, free of burrs or marks, and that the shaft surface has the hardness and finish suitable for a seal lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it unevenly. If the shaft has play or is worn in the contact area, the sealing will not be effective even if the size is correct. If in doubt, consult the manufacturer's data sheet.

If you need an equivalent seal or a nearby size, the most practical thing is to send us the 8774 code along with the shaft, housing and height dimensions you have. With that data we can look for an alternative within the same DBH line or from other brands we carry. We can also advise you if the Lx design is not the one that corresponds to your application and a different type of lip or case is needed.
