The DBH 5280 is a single-lip radial shaft seal built to keep oil or grease in and dust or water out where a shaft rotates. Its Lx construction uses a metal outer case with a sealing lip, press-fit into the housing and running against the shaft. With a 68 mm shaft, 90 mm housing bore and 10 mm width, it fits gearboxes, pumps and transmission equipment. MR Industrial Accessories supplies this brand and helps you match the seal to your application.

Read the size from the code before anything else: shaft 68 mm, housing 90 mm, width 10 mm. The 5280 number pins down that exact size in the DBH line, so it is the reference to quote or to cross to another maker. Lx tells you the style: a radial lip seal with a metal body, installed by pressing it into the housing while the lip rides on the shaft.

Typical service is any rotating assembly that holds lubricant: gearboxes, centrifugal pumps, mixers, conveyors and machine tools. In dusty or wet surroundings the lip also blocks contaminants from reaching bearings and gears. Treat it as a wear part. An oil weep at the seal area or unusual noise usually means it is time to pull it.

Before ordering, confirm the three dimensions against the housing bore and shaft you have. Inspect the shaft surface as well; burrs or a worn groove will shorten lip life. On installation, coat the lip with the same oil or grease used in the unit, keep the seal square to the shaft, and press with a tube or spacer that contacts only the outer case, never the lip.

If the exact size is not what you need, send the 5280 reference plus the measurements of the old seal: shaft diameter, outer diameter and width. That is enough for us to search an equivalent from another brand with the same function. We can also guide you on lip type and seal material based on the fluid and the operating temperature.
