The DBH 5820 is a radial shaft seal from a brand we supply, built to keep lubricant in and contaminants out where a shaft turns. Its Lr lip configuration suits a range of rotating equipment. The three dimensions to match are shaft 15.87 mm, housing bore 28.78 mm and height 9.52 mm.

Reading the code is straightforward: DBH 5820 identifies the seal, and the three figures that follow in the catalog are the ones that matter at the bench. Shaft diameter (d) is 15.87 mm, housing bore (D) is 28.78 mm and overall height (h) is 9.52 mm. The Lr designation points to a particular lip geometry, so check that the lip style matches the application before you install.

Seals of this type show up in pumps, electric motors, gear reducers, gearboxes and other power transmission equipment. Their job is to hold oil or grease inside the housing and to keep dust, water and particles away from bearings and internal parts. You will find them in food processing, chemical plants, automotive operations and agricultural machinery.

Installation is where most seal failures start. Clean the shaft and the housing bore, and remove any burrs or sharp edges that could nick the lip. Coat the lip with the same oil the equipment uses, then seat the seal squarely. Confirm the dimensions against the application: shaft 15.87 mm, housing bore 28.78 mm, height 9.52 mm. If the Lr lip is not right for the service, ask about other options.

When you need a replacement, send the part number and we will check for the exact reference or propose a comparable seal based on the dimensions and the operating conditions.
