A radial shaft seal from the DBH line, the DBH 5435 keeps lubricant where it belongs and keeps contaminants out. It fits a 16 mm shaft, a 25 mm housing bore and a 6.00 mm height. Seals like this one are routine replacement items on motors, pumps, reducers and other rotating equipment, and a correct fit is what protects the bearings and bushings around them.

The code 5435 identifies the size within the DBH range. The three values to check before ordering are shaft 16 mm, housing bore 25 mm and height 6.00 mm. The Lx designation tells you the seal has one sealing lip with a spring, which is the usual choice for a lubricated rotating shaft. DBH is one of the brands we supply, and we can also review other lines we carry if you need an alternative.

You will find this type of seal wherever a shaft turns inside a housing and oil or grease has to stay contained: electric motors, centrifugal pumps, gear reducers, transmission cases, compressors and machine tools, as well as fans, industrial washing machines and other process equipment. The lip material has to suit the speed and temperature of the application, so those two conditions are worth confirming before you install.

Installation is straightforward but unforgiving. Inspect the shaft for burrs or deep marks, coat the lip with the same lubricant used in the equipment, and press the seal in squarely without hitting the lip. When the original part carries a different designation, match it by the three dimensions: shaft diameter, housing bore and height. Peripheral speed, operating temperature and the fluid being retained are the factors that decide whether a given seal is the right one.

For a replacement, send the code 5435 or the measurements of the old seal over WhatsApp. We handle technical questions and can point you to options from the same brand or from other lines we carry. It also pays to look at the shaft and housing before fitting a new seal, since heavy wear in either surface will keep a new seal from doing its job.
