The DBH 5856 is a radial shaft seal used on rotating shafts to keep lubricant where it belongs and to block dust, water and other contaminants from reaching the bearing area. It measures 30.10 mm at the shaft, 42.82 mm at the housing bore and 9.52 mm in height, and its Lz designation describes how the lip and outer body are built. You will find this type of seal in pumps, motors, gearboxes and similar industrial equipment.

The code breaks down into two parts: the DBH brand and the number 5856. The three dimensions that matter when matching a replacement are shaft 30.10 mm, housing 42.82 mm and height 9.52 mm. The Lz designation refers to a particular lip and outer body construction. The seal is pressed into a cylindrical bore and its lip rides against the rotating shaft surface.

You will typically find this seal in centrifugal pumps, electric motors, speed reducers, line shafts and process equipment that runs continuously. In each case it holds oil or grease in and keeps contamination out, protecting the bearings and bushings nearby. Because it is a wear part, it should be replaced once leaks appear, the mechanism starts making unusual noise, or dirt works its way inside.

Before ordering, confirm that the shaft and bore in your equipment match the dimensions above, and check that the 9.52 mm height fits the cavity without being compressed. At installation, coat the lip with the oil or grease used in the application, seat the seal square to the shaft, and avoid hitting it directly. A shaft with grooves or wear may need repair or a seal with an auxiliary lip. A clean sealing area also helps the seal last.
