The DBH 5512Sil is a radial shaft seal built to the Mx pattern, a lip-and-metal-case design that presses into a cylindrical bore. Its working envelope is a 25.00 mm shaft, a 47.00 mm housing and an 8.00 mm height, so it fits rotating assemblies where oil or grease has to stay in and dust, water and grit have to stay out. MR Industrial Accessories supplies this seal as part of its seals and oil seals range for maintenance and repair work.

Reading the code helps when you are matching a replacement. The 5512Sil portion carries the size and construction of the seal, while DBH identifies the line it belongs to and Mx describes the lip-and-case configuration. The numbers translate to shaft 25.00 mm, housing 47.00 mm, width 8.00 mm. Because the case is metal, the seal is installed by pressing it squarely into the bore rather than by hand.

You will find this size on equipment where a shaft turns inside a lubricated housing: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and general process machinery. In dusty or wet areas the same seal keeps particles out and holds the lubricant in place. That makes it a routine item on maintenance schedules and during rebuilds of rotating equipment.

Selection comes down to matching three values against the original part: shaft diameter, housing diameter and height. The shaft surface matters just as much. It should be smooth and free of deep grooves, since a worn journal will not let the lip seat properly. A light film of lubricant on the lip before pressing, plus a driver that keeps the seal straight and undamaged, goes a long way toward a clean install. If the application runs hot or fast, ask our team about the lip material.

If the size you need is different, or you are looking for a cross-reference, send the complete code, the measurements taken from the old seal, or a photo of the part. With that information we can search the DBH line or other brands we carry for a suitable match. We can also help when the housing is non-standard or the original seal has a detail worth replicating.
