MR Accesorios Industriales supplies it as part of its seals and oil seals line.

This item is a DBH brand radial shaft seal, identified by part number 8831. Its dimensions are 240 mm shaft, 280 mm housing and 18 mm height, with an Lz design. The Lz design corresponds to a lip and case configuration that allows it to seal against the shaft and fit into the housing. It is a large-section oil seal, intended for equipment where the shaft has a considerable diameter and oil or grease must be contained during rotation.

Typical applications for an oil seal of this size include large gearboxes, mills, process centrifugal pumps, mining and cement equipment, and industrial drives with 240 mm shafts. It is also used in paper machines and steel industry equipment. In every case, the function is the same: retain the lubricant inside the assembly and block dust, water or particles that could damage bearings or gears.

To install an oil seal of these dimensions, check that the shaft is clean, free of burrs and marks, and that the sealing surface has the proper hardness and roughness. The housing must be free of dents and have the correct diameter. During installation, lubricate the lip and use a tool that presses on the outer edge, never on the lip. If the equipment runs at high speed or under high pressure, check the manufacturer's product page to confirm the mounting direction and the elastomer type.

If you need an oil seal equivalent to the 8831 or a nearby size, the most practical approach is to send us the part number, the shaft, housing and height dimensions, and a photo of the old seal. With that data we can look for an alternative within the DBH line or other brands we supply. We can also advise you if the Lz design is not the right one for your application and a different lip type or material is required.
