A radial shaft seal such as the DBH 5223Vit sits in the housing bore and wipes against the turning shaft, so lubricant stays where it belongs and outside contamination stays out. This one takes a 45 mm shaft, a 65 mm housing bore and a 10 mm width, and it uses the Lz design. Sizes like this turn up often in gearboxes, pumps and other power transmission assemblies. MR Industrial Accessories LLC supplies this brand and can help you match the seal to the job.

Reading the reference: DBH 5223Vit is the item designation, and the three figures that matter are shaft 45 mm, housing 65 mm and width 10 mm. Lz tells you the seal has one lip with a spring, which is the usual choice for a rotating shaft that runs with oil or grease. Seals in the 5223 series share a compact cross-section built for standard housing bores. In service, the lip rides on the shaft while the outer case stays fixed in the housing, so the assembly works as a barrier in both directions.

You will find a seal this size in gear reducers, centrifugal pumps, electric motors, line shafts and process machinery. The job is always the same: hold the lubricant in the sump and keep dust, washdown water and process residue away from bearings and gears. It also serves as a secondary closure where the assembly sees a pressure differential or a steady spray of oil.

Before pressing one in, inspect the shaft for nicks, burrs or a worn track, and make sure the bore is clean and still round. The running surface should be ground and hard enough to resist wear. Coat the lip with the oil used in the unit, then drive the seal with a tube that contacts the metal case only, never the lip. When you are replacing a failed seal, look at the shaft as well, since a scored surface or end play will cut short the life of the new part.

For a quote, send the full seal reference, the brand and the shaft, bore and width measurements. With those details we can cross the 5223 series or check other DBH options and the other brands we carry. A photo of the removed seal or the housing drawing works too, and the designation does not have to be identical, as long as the dimensions and lip style line up.
