Part 5147 from DBH is a radial shaft seal built for rotating shafts that need their lubricant kept in and outside contamination kept out. It measures 50 mm at the shaft, 72 mm at the housing bore and 12 mm in height, and it comes in the Lx design. MR Industrial Accessories carries it within its seals and oil seals range for maintenance and repair work.

Reading the label is straightforward. The 5147 is the DBH designation, while the three figures give the fit: shaft side 50 mm, housing bore 72 mm, overall height 12 mm. The Lx version uses a single lip with a spring, which is the usual choice for lubricated rotating shafts. Because DBH is one of the brands we supply, each seal reaches you with its factory marking intact.

You will find seals like this one in gearboxes, pumps, electric motors, rollers, mixers and other transmission assemblies. Two jobs are handled at once: the lip holds oil or grease where it belongs, and the same lip keeps dust, chips and moisture from working their way in. In dirty or damp conditions, that contact between lip and shaft is what keeps the assembly running clean.

Before fitting, inspect the shaft for burrs, scratches or wear and confirm the bore is clean and round. Put a light film of lubricant on the lip, then seat the seal with a tube or driver of the right diameter, applying force on the outer edge rather than on the sealing element. Shaft speed, operating temperature and the fluid being sealed all influence the correct choice, so if the old seal differs in height or design, compare it against the product data first.

To get a quote, message us on WhatsApp with code 5147 or the size 50 x 72 x 12 mm. A photo of the removed seal or the equipment part number also works well. We confirm the designation and, when needed, point you to a compatible option from the DBH range or another brand we carry.

Seals sit alongside bearings, housings, power transmission components, bushings, lubrication products and mounting tools in what we supply to plants and workshops across the United States and in several Latin American countries.
