The DBH 5287 is a radial shaft seal with a single sealing lip and metal case, known as the Lx design. It mounts on the shaft and inside the housing to keep lubricant in and contaminants out. Shaft diameter is 25 mm, housing diameter 50 mm and height 10 mm. This is a common replacement item in gearboxes, pumps, motors and power transmission equipment, and MR supplies it to customers across the United States, Canada, Mexico and South America.

The part number 5287 identifies this seal in the DBH line, and it is the reference printed or engraved on the product itself. When you order, that number is what ties your request to the exact size and design. The three dimensions to check are shaft 25 mm, housing 50 mm and height 10 mm, matching the d, D and h values used in seal catalogs.

Seals of this size show up in gearboxes, centrifugal pumps, electric motors, compressors and other power transmission assemblies. Their job is to hold oil or grease inside the housing and block dust, water and particles from reaching the bearings. You will also find them on machine tools, conveyors, and agricultural or road equipment where shafts turn on bearings or bushings.

Before installing, inspect the shaft for burrs or wear and make sure the housing is clean and free of dents. Lubricate the lip with the same oil or grease used in the equipment, then seat the seal perpendicular to the shaft without tilting it. If the shaft has a deep groove, a seal with the lip in a different position may be the better choice. Speed, temperature and fluid type all affect selection, so ask if you are unsure.

If you need an equivalent or another size, send the part number 5287 or your current dimensions: shaft diameter, housing diameter and height. With that information our team can search the seal line for the closest match. We can also help when the original has a special design or the housing has an unusual depth. The more details you provide, the more accurate the recommendation.

To request a quote, send the part number by WhatsApp or email. If you tell us which equipment the seal is mounted on, we can help confirm that the size and design are right before you install it.
