The DBH 5505 radial shaft seal is a lip seal that sits on the shaft and inside the housing, keeping lubricant in and dust, water or particles out. Its three published dimensions are shaft 30.10 mm, housing 42.86 mm and height 6.35 mm, which puts it in compact-section work. It is a wear part: once the lip hardens or a leak shows up, it gets replaced. MR Industrial Accessories supplies this brand and can help confirm the right size.

This seal belongs to the DBH line and carries the code 5505. The listed attributes are shaft diameter 30.10 mm, housing diameter 42.86 mm and height 6.35 mm, with the Mz design indicated. Mz is a single-lip configuration with a metal body that fits straight housings. Those numbers are what set the mounting: the inner diameter runs on the shaft, while the outer diameter seats under pressure in the cavity. If your equipment calls for a different size, an equivalent in the same series can be looked up.

Seals of this section show up in gearboxes, pumps, electric motors, transmission shafts and process equipment where rotation is continuous and oil or grease is present. They also appear in agricultural machinery, conveyors and washing equipment, where they have to hold back dust and water in addition to retaining lubricant. Lip material and spring selection depend on the fluid, the temperature and the rotation speed, so it pays to have those details ready when you ask for a quote.

Before mounting, check that the shaft has no burrs, wear or scoring and that the housing is clean and free of deformation. Lubricate the lip before inserting it and seat it straight so it is not damaged. The 6.35 mm height calls for a cavity of the proper depth. If the shaft shows a marked groove, shifting the seal slightly or using a repair sleeve is sometimes worth considering. Send us the condition of your equipment and we can advise.

To quote code 5505, send a photo of the old part, the shaft and housing diameters measured with a caliper, and the type of fluid. With that information we look for the equivalent seal within the DBH line or from other brands we carry. We can also check whether the Mz design suits your application or whether another profile would work better.
