The DBH 8255 is a radial shaft seal built to keep oil or grease where it belongs and to keep dust and water out of rotating equipment. It seats in the housing with a press fit while a flexible lip rides against the shaft. Gearboxes, pumps, motors and power transmission assemblies all rely on seals of this type as a wear item. MR Industrial Accessories supplies this brand and helps confirm the size before a quote goes out.

Read the size in this order: shaft 26 mm, housing 38 mm, height 5.00 mm. The Lx configuration tells you the seal has one sealing lip and a metal outer case, so it is made to be pressed into a cylindrical bore. Within the DBH line, 8255 is the code that pins down this particular size. Tolerances and lip compound are checked against the manufacturer's data sheet before we quote.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, reducers and other power transmission equipment, as well as machine tools, compressors and hydraulic systems wherever a rotating shaft has to be separated from the surrounding environment. The job is the same everywhere: hold the lubricant in and keep particles out, so bearings and gears are not worn down ahead of schedule.

Installation starts with clean surfaces. The shaft and bore should be free of burrs and scratches, and the lip gets a coat of lubricant before the seal goes in. Press it in squarely to the shaft; hammer blows that distort the case will cause leaks. A shaft with a visible wear track may call for a seal positioned with the lip on a fresh surface. Speed, temperature and lubricant type all feed into selection, and those values are verified against the manufacturer's data sheet.

Looking for an equivalent? Send the 8255 number together with the shaft, housing and height dimensions. A photo of the removed seal or the assembly drawing works just as well. From there we search within the same series or across the other brands we carry. MR Industrial Accessories reviews the details with you so the part you order is the part that fits.
