The DBH 8206 oil seal is a single-lip radial seal that prevents oil or grease leaks and blocks the ingress of dust and water in equipment with a rotating shaft. Its Mz design and its dimensions of 55 mm shaft, 78 mm housing and 12 mm height make it suitable for gearboxes, pumps, electric motors and industrial transmissions. MR Accesorios Industriales supplies it as part of its line of seals and oil seals for replacement and maintenance.

The DBH 8206 is a radial oil seal of Mz design, with 55 mm shaft diameter, 78 mm housing diameter and 12.00 mm height. The sealing lip, generally made of elastomer, runs on the rotating shaft and retains the lubricant inside the assembly, while the metal case is press-fitted into the housing. The designation 8206 follows the manufacturer's DBH coding and allows the part to be identified without ambiguity when replacing it.

It is used in equipment where a shaft rotates inside a fixed housing and lubricant must be contained: gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers and belt or chain drives. It also appears in applications exposed to dust or water, where the seal performs a dual function of sealing and protection. It is a wear part that should be replaced when leaks or noise are detected in the lip area.

To select the correct oil seal, check that the three dimensions match the shaft, the housing and the available depth. The Mz design defines the geometry of the lip and the metal case; if the original equipment has another variant, consult us before replacing it. During installation, lubricate the lip, avoid striking it and make sure the shaft has no burrs or splines that could damage the elastomer. Cleaning the housing beforehand improves seating and the service life of the seal.

If you need a nearby size or an equivalent from another brand, send us the full code, the shaft, housing and height dimensions, and a photo of the old part if you have one. With that data we can look for the alternative within the DBH line or other brands we supply. We can also guide you if the seal is mounted on a worn shaft or if the housing has tolerances outside the usual range.
