The DBH 8738Sil radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 12 mm shaft, 25.40 mm housing and 8.00 mm height, and Lx design, it is a commonly used size in power transmission equipment and light machinery. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a DBH 8738Sil radial shaft seal, identified by its designation 8738Sil. Its dimensions are shaft (d) 12 mm, housing (D) 25.40 mm and height (h) 8.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The elastomeric lip runs on the shaft and the metal case fits into the housing. It is a standard replacement part in assemblies where oil or grease must be separated from the environment.

Typical applications for a seal of this size include small gearboxes, electric motors, centrifugal pumps, compressors, fan shafts and belt or chain drive equipment. It is also used in machine tools, washing equipment and irrigation systems. In every case it performs the same function: keeping lubricant inside the assembly and preventing contaminants from entering that would accelerate wear on bearings and gears.

To select and install a seal, verify that the shaft and housing diameters match the values on the product page, that the shaft has no burrs or splines in the sealing area and that the surface is smooth. The seal is pressed in perpendicular, without striking the lip, and it is advisable to lubricate the lip before assembly. If the shaft shows wear, a neighboring size or a seal with an auxiliary lip can be evaluated, always confirming compatibility with the manufacturer.
