The DBH 8824 oil seal is a single-lip radial seal that mounts on the shaft and closes against the housing to retain lubricant and stop the entry of dust, water or particles. Due to its dimensions —171.5 mm shaft, 196.9 mm housing and 11.11 mm height— it is used in large equipment, where the seal is the barrier that protects bearings and gears. MR Accesorios Industriales supplies it as an official brand.

This item is a DBH 8824 radial shaft seal, identified by its designation 8824. Its dimensions are 171.5 mm shaft diameter (d), 196.9 mm housing diameter (D) and 11.11 mm height (h). The Lz design corresponds to a single sealing lip with spring, intended for rotating shafts with permanent lubrication. It is a replacement part, not a generic component: the three dimensions and the design must match the original housing.

Typical applications of a seal of this size appear in large gearboxes, mills, process pumps, mixers and power transmission equipment with large-diameter shafts. In all these cases the function is the same: keep the oil or grease inside the assembly and prevent contaminants from entering that accelerate wear of bearings and gears. It is also used as a closure at shaft ends that are exposed to the environment.

To install it correctly, verify that the shaft and housing diameters match the values on the product page, that the shaft has no burrs or marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tool that rests on the outer edge, never on the lip. If the equipment operates with high vibration or temperature, consult us and we will evaluate the most suitable design.

If code 8824 is not the one you need, or if the shaft is worn and you want a nearby size, send us the dimensions taken with a caliper —shaft diameter, housing and height— and the type of lubricant the equipment uses. With that data we look for the equivalent seal within the DBH line or other brands we supply, and we confirm the technical alternative.

MR Accesorios Industriales supplies the DBH brand as an official brand. If you already have the code at hand, send it on WhatsApp along with a photo of the old seal and the shaft and housing dimensions: with that we prepare the quote and indicate whether the same reference or a mounting variant is best.
