A radial shaft seal such as the DBH 5291 keeps lubricant where it belongs and keeps contaminants out. It sits press-fitted in the housing bore while its flexible lip rides against the rotating shaft, sealing the gap between the two. Because the lip wears against the shaft, this is a consumable item: once grease or oil starts weeping past it, or the shaft surface shows scoring, replacing the seal early protects the bearings behind it.

The DBH 5291 carries the Lx design. Three measurements decide whether it drops into your assembly: the bore it presses into measures 50.00 mm, the shaft it runs on measures 32.00 mm, and its overall height is 6.00 mm. Confirm each of the three against the old part before you order, since a mismatch on any one of them means it will not seat or seal correctly.

Gearboxes, pumps, motors, rollers and similar transmission equipment are where this seal type is normally found: a shaft turning inside a lubricated housing. In plants handling food, water or heavy dust, the seal works in both directions at once, holding oil in and keeping grit and moisture out. Dirty operating conditions are usually where the first signs of seal failure appear.

Selection goes beyond the three dimensions. Shaft speed, operating temperature and the lubricant in use all affect how the lip performs. A lip that runs dry, or a shaft with a worn track, can ruin a new seal quickly. Install it square to the bore, avoid striking the lip, and coat the sealing edge with lubricant before sliding it over the shaft. Any burr or groove on the shaft will cut the new lip on the first rotation.

If the exact code is not what you need, MR can cross-reference within the same DBH line. Send the marking on the old seal, the shaft, housing and height measurements, and a photo of the installation. The team checks that data against the manufacturer's information and tells you which option fits, so the equipment is opened only once.

MR supplies the DBH brand, so the seal comes with its original identification. When the code is already known, send it by WhatsApp or email with the quantity needed and the team will prepare a quote. If anything is unclear, write in anyway and they will help confirm the size and suggest equivalents before you buy.
