The DBH 1284 oil seal is a single-lip radial shaft seal that prevents oil or grease leaks and blocks the ingress of dust and water in rotating equipment. It mounts on a 47 mm shaft and fits into an 80 mm bore, with a height of 7.50/26.00 mm and Ms design. It is a wear part that should be replaced when lubricant leakage or contaminant ingress appears. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This DBH 1284 oil seal has a shaft diameter of 47 mm, a housing diameter of 80 mm and a height of 7.50/26.00 mm. The Ms design corresponds to an oil seal with a sealing lip and a specific construction configuration that combines a metal body with an elastomeric lip. The designation 1284 identifies the exact size within the DBH line. It is a radial sealing component that works on the rotating shaft and seats in the fixed housing, with the height split into two values that indicate the lip and body profile.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where oil or grease must be retained and dirt kept out. It also appears in applications exposed to dust, water or chips, where the sealing lip serves a dual function: retaining the lubricant and acting as a barrier against contaminants. It is common in industrial plant maintenance, workshops and mobile equipment operating in demanding environments.

To install it, verify that the shaft is clean, free of burrs or marks, and that the sealing surface has the proper roughness. Lubricate the lip before inserting it and use an installation tool that presses on the outer diameter, never on the lip. The oil seal must sit perpendicular to the shaft and at the correct depth. If the housing has burrs, clean it before installing. Selection depends on speed, temperature and the fluid to be retained; if you have doubts, consult us with your equipment data.

If you need an equivalent or a nearby size, send us the full code, the shaft and housing dimensions, and a photo or sample of the old oil seal. With that data we can look for an alternative within the same family or suggest a compatible replacement. We can also advise you if the Ms design is not suitable for your application and a different lip type or material is better.
