For rotating shafts that need lubricant kept in and contaminants kept out, the DBH 5434Sil oil seal is a direct option. It comes in the Lz Sil design, which pairs a sealing lip with a construction meant to work against a lubricated shaft. The size is written as 15 x 25 x 6 mm, so the shaft measures 15 mm, the housing bore 25 mm and the height 6.00 mm. Maintenance and purchasing teams use this seal on pumps, motors, reducers and other industrial equipment, and MR Industrial Accessories supplies the DBH line for those replacements.

Reading the code helps before you order. The 5434Sil number carries the size and the design together, while Lz Sil tells you which lip and body configuration you are getting. Confirm all three values against your equipment first: shaft 15 mm, housing 25 mm, height 6.00 mm. A seal that matches on the shaft but not on the bore, or the other way around, will not seat or seal correctly.

You will find this seal on centrifugal pumps, small electric motors, speed reducers, compact compressors and transmission assemblies. In each case it holds oil or grease inside the assembly and keeps dust, water and other particles away from bearings and gears. Treat it as a wear part: once oil starts weeping past the lip or the area begins to make unusual noise, plan the replacement.

Installation decides how long the seal lasts. The shaft should be clean, free of burrs and nicks, and lightly lubricated before the seal slides on. Check that the housing bore is sound and at the right diameter. Press the seal in with a tube or socket that contacts the metal case only, never the lip. If the shaft itself shows wear, an auxiliary lip or a different size may be the better route; speed, temperature and lubricant type all feed into that choice.

If you are working from an equivalent rather than the original number, send the 5434Sil code or the exact dimensions you measured. A photo or a sample also works when the marking is gone. From the housing and shaft measurements, the team can help you identify the right seal.
