The DBH 5053Sil radial shaft seal is a lip seal that blocks the passage of oil or grease on rotating shafts and keeps out dust and water. With its dimensions of 25 mm shaft, 40 mm housing and 8 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales sells this brand and advises you so you choose the right seal according to the type of lubricant, speed and shaft finish.

This item is a DBH radial shaft seal with the designation 5053Sil, with the following dimensions: shaft diameter 25 mm, housing diameter 40 mm and height 8.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The elastomeric lip rests on the shaft and the spring maintains contact pressure; the outer body is press-fitted into the bore. It is a wear part that is replaced when lubricant leakage or contaminant ingress appears.

Typical applications of a 25 x 40 x 8 mm seal are gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain drive equipment. It is also found in machine tools, washing equipment and irrigation systems. Whenever there is a rotating shaft passing through a housing with lubricant inside, this type of seal performs the function of retaining the oil and stopping outside dust.

To install it, check that the shaft is clean, free of burrs and marks, with adequate hardness and roughness, and that the housing has the correct diameter and chamfer. Lubricate the lip before inserting it and use an installation tube that presses on the outer edge, never on the lip. If the seal works at high speed, with high pressure or with extreme temperatures, consult us and we will evaluate a design with a different material or geometry.

If you need an equivalent or a nearby size, send us the code 5053Sil, the shaft diameter and the housing diameter. With that data we search the DBH line or another compatible alternative. We can also offer you the same seal in another height or with a different design if space allows. The more complete the equipment information, the faster we give you a useful answer.
