The DBH 5053 is a radial shaft seal from the DBH line, built for rotating shafts. Its dimensions are 25 mm shaft diameter, 40 mm housing bore and 8 mm height. It keeps oil or grease inside and blocks dust and water from entering. You will find it in gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories supplies this brand and helps you select the right seal for the job.

The 5053 code identifies one specific size within the DBH line. This seal uses the Lx design: a single sealing lip with a spring and a metal outer body. The lip rides against the shaft while the outside of the seal sits in the housing bore, so lubricant stays in and bearings stay protected. Shaft diameter is 25 mm, housing bore is 40 mm and the height is 8.00 mm. These three values are what you check before ordering.

You will see this seal in gearboxes, centrifugal pumps, electric motors, compressors, transmission shafts and process equipment. In every case it presses into the housing and seals against the rotating shaft. It also works where dust or water exposure is moderate, as long as the shaft speed and the operating temperature stay within what the lip material can handle.

Before installing, inspect the shaft for burrs, scratches or a wear groove. Lubricate the lip, then seat the seal with a press or a proper driver. Do not strike the lip. When choosing a seal, look at shaft speed, working temperature and the fluid being retained. If the shaft already has a groove, an offset lip or a repair sleeve may be the way to go. Confirm compatibility against the manufacturer's data sheet.

If you need an equivalent, send the 5053 code or the dimensions of your current seal: shaft diameter, housing bore and height. MR Industrial Accessories can locate the exact size in the DBH line or propose a compatible alternative. We also handle other seal and oil seal brands, so ask if you cannot find your size.
