Part of our seals and oil seals range, the DBH 5391 is a radial shaft seal built for shafts that turn inside a housing. It keeps lubricant where it belongs and keeps dust, water and other contaminants out. Because the lip wears against the shaft over time, the seal is a service item: once oil starts weeping or dirt works its way in, it gets swapped. The Lx design combines a sealing lip with a metal body.

Reading the code: DBH identifies the seal family, 5391 is the item designation, and the size string gives shaft, housing and height in that order. Here that means shaft 84 mm, housing 110 mm, width 16.00 mm. The lip rides on the shaft while the outer diameter presses into the housing bore, and that pairing is what holds the lubricant in and the contamination out.

You will find this seal on gearboxes, pumps, electric motors, rollers and other transmission equipment where a rotating shaft passes through a housing. It typically sits in a cover or on a housing flange, with the lip facing the oil side. Maintenance teams in agricultural, industrial and process plants rely on it to keep bearings and gears protected from what is floating around outside.

Before fitting, confirm the shaft and bore are clean and free of burrs or scratches, and that the shaft surface meets the required hardness and roughness. Coat the lip with lubricant, then seat the seal square to the shaft rather than driving it in with direct hammer blows. If the shaft shows a wear groove, a seal with the lip positioned differently may be the better call. Speed, temperature and the lubricant in use all factor into selection.

To get a quote on code 5391, send the measurements taken from the old seal: shaft diameter, housing diameter and height. A photo of the part and the housing helps too. With that information we can point you to a seal in the same Lx design. When the exact size is not listed, we look at other options in the DBH line.

Send code 5391 or the dimensions 84x110x16 mm on WhatsApp and our team confirms the quote along with any alternatives. Questions about installation or how to choose the right seal are welcome, and our technical staff can walk you through it.
