The DBH 5088 radial shaft seal is a lip seal that prevents oil or grease leaks and dust ingress on rotating shafts. It is press-fitted into the housing and its flexible lip runs on the shaft. It is a wear part: when lubricant loss or contaminant ingress appears, it is replaced. MR Accesorios Industriales carries this brand and helps you identify the correct size for your equipment.

This item is a DBH 5088 oil seal, with the dimensions indicated in its designation: shaft diameter 17 mm, housing diameter 34 mm and height 4.00 mm. The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts with lubrication. The 5088 nomenclature identifies the size; it is not an internal serial number. If your equipment calls for a 17 x 34 x 4 mm seal, this is the code you need to look for.

It is used in gearboxes, electric motors, pumps, compressors, machine tools and transmission equipment. In general, any assembly where a shaft rotates inside a housing and oil or grease must be retained while dust or water is kept out. It also appears in low-speed applications and in equipment where axial space is limited, as in this case with a 4 mm height.

To install it, verify that the shaft is clean, free of burrs and marks, and that the surface where the lip rests has a fine finish. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or spacer that presses on the outer ring, never on the lip. If the housing has a chamfer, respect the angle so as not to damage the seal. Selection depends on speed, temperature and the type of lubricant; if you do not have that data, ask us.

If you need an equivalent, send us the full code of the seal, the shaft, housing and height dimensions, and a photo of the old part if you have it. With that we review alternatives within the DBH line or from other brands we carry. We also tell you the standard size that replaces the one you are using, always respecting the original housing dimensions.
