The DBH 8480 oil seal is a single-lip radial shaft seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that wear down bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a fixed body. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

The DBH 8480 is a radial shaft seal with the following dimensions: shaft diameter 52 mm, housing diameter 68 mm and height 13.50 mm. The design indicated by the manufacturer is Mx, which corresponds to a sealing lip with spring and metal case for press-fit mounting. These three dimensions are what determine whether the seal fits your equipment: the shaft, the housing and the overall width. Any variation in any of them changes the part number.

Seals of this size are found in rotating equipment where oil or grease must be separated from the environment. They appear in gearboxes, centrifugal pumps, electric motors, rollers and conveyors. Also in machine tools and process equipment where the shaft rotates at moderate speed and the working temperature is not extreme. If the seal fails, lubricant loss contaminates and accelerates wear on bearings and gears.

To install a seal, check the condition of the shaft: free of burrs, free of marks from the previous lip and with the proper surface roughness. The housing must be clean and free of deformation. It is recommended to lubricate the lip before inserting it and to use an installation tube that presses on the outer edge, never on the lip. If the shaft is worn, a nearby size or a seal with the lip in a different position is sometimes better. That is determined by the manufacturer's data sheet.

If you cannot find the exact part number or need a nearby size, send us 8480 along with the shaft, housing and height dimensions. A photo of the old seal and the housing also works. With that data we look for the equivalent in the same brand or in another line we carry.

To complete your inquiry, have the shaft diameter, housing diameter and height on hand. If the seal works under pressure, high temperature or high peripheral speed, let us know so we can evaluate the lip material. The part number 8480 is the starting point. Write to us on WhatsApp and we will verify it against the manufacturer's data sheet before requesting a quote.
