The DBH 9051 radial shaft seal is a lip seal that prevents oil or grease leakage and keeps dust out of rotating shafts. Thanks to its compact size, it is used in equipment where space is limited and rotation speed is moderate. MR Accesorios Industriales carries this brand and advises you so you choose the right seal according to shaft size, housing and type of lubricant.

This item is a DBH 9051 radial shaft seal with the following dimensions: shaft diameter 18 mm, housing diameter 28 mm and height 4.00 mm. The Lx design indicates a single-lip configuration with spring, intended to retain lubricant in one direction of rotation. The elastomeric lip rests on the shaft and the spring keeps contact pressure constant. The outer case is metal and is press-fitted into the housing. It is a replacement part for maintenance, not a structural component.

Typical applications of an 18 x 28 x 4 mm seal include small electric motors, water pumps, compact gear reducers, gearboxes, compressors and low-power transmission equipment. It is also used in machine tools, tillage equipment and hydraulic systems where lubricant must be contained and bearings protected from dust and moisture. It is commonly found on fan shafts, mixers and low-speed conveyors.

For installation, check that the shaft has no burrs or wear and that the surface where the lip rests is polished. Lubricate the lip with the same grease or oil used in the equipment before inserting it. The seal must enter perpendicular to the housing, without blows that deform the case. If the shaft shows a groove or marked wear, consider replacing it or using a seal with the lip in a different position. Selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a nearby size, send us the part number 9051 or the current dimensions (shaft, housing and height). It also helps if you tell us the equipment where it is mounted and send a photo of the old seal. With that data we check whether there is an alternative in the same brand or in another line we carry. The part number does not need to match exactly: what matters is that the three dimensions and the lip type are compatible.
