The DBH 8272 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 18 mm shaft diameter, 30 mm housing diameter and 7 mm height place it in the range of compact seals, typical of pumps, small electric motors, gearboxes and light transmission equipment. MR Accesorios Industriales carries this brand and advises you on choosing the right seal.

The DBH 8272 is a seal of Lx design, with a sealing lip and metal case. Its dimensions are 18 mm shaft diameter (d), 30 mm housing diameter (D) and 7 mm height (h). The Lx design indicates a single-lip configuration with spring, suitable for rotating shafts with lubrication. The elastomer lip works against the shaft surface, while the outer diameter is press-fitted into the bore. This combination of dimensions and design makes it suitable for tight spaces where a reliable closure is needed.

Typical applications for a seal of this size include small centrifugal pumps, low-power electric motors, gearboxes and compact gear cases, fan shafts, belt drive equipment and machine tools. In all cases, the function is the same: prevent oil or grease leaks and protect bearings and gears from the entry of contaminants. It is also used in agricultural, road and material handling equipment where dust and moisture are present.

To correctly install the DBH 8272, verify that the shaft measures 18 mm and has a surface free of scratches or wear; the housing must measure 30 mm and be clean and free of burrs. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows a worn track, consider a repair sleeve or an alternative size. Selection depends on speed, temperature and the fluid to be retained; if in doubt, consult us with your equipment data.
