The DBH 1027 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. Its Mx design and its dimensions of 57.15 mm shaft, 81 mm housing and 12.70 mm height place it in transmission and rotation equipment under heavy use. MR Accesorios Industriales carries it as an official brand and ships throughout the country.

This item is a radial shaft seal from the DBH line, identified with part number 1027. Its nominal dimensions are 57.15 mm shaft diameter, 81 mm housing diameter and 12.70 mm height. The Mx design defines the geometry of the lip and the metal body, intended for standard housings. It is a direct replacement part: it is press-fitted into the cavity and works with the lip resting on the rotating shaft. It is not a static seal or an O-ring: its function is dynamic and continuous.

Seals of this size appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and process equipment. They are also used on fan shafts, mixers and machine tools where there is oil or grease lubrication and contact with a dirty environment. In all these cases the seal performs two tasks at once: it prevents lubricant leaks to the outside and slows the advance of contaminants toward the bearings. If the equipment runs with vibration or misalignment, the lip suffers more and its service life is shortened.

To select the seal correctly, verify that the three dimensions match the shaft, the housing and the depth of the cavity. Check the condition of the shaft: a scored, worn or burred surface ruins the new lip within a few hours. The housing must be clean, free of impacts and with the entry chamfer in good condition. During installation, lubricate the lip with the same grease or oil used in the equipment, seat the seal perpendicular and push with a tube or press that bears on the outer ring, never on the lip. If the shaft is damaged, consider a repair sleeve before installing the seal.

If you need a nearby size or an equivalent, send us part number 1027 along with the shaft, housing and height dimensions shown on the nameplate or the equipment drawing. A photo of the old seal with a caliper next to it also works. With that data we cross-check the size against the catalog and offer you alternatives from the same brand or from another line that fits the same cavity. If the Mx design is not the right one, we tell you before quoting.
