The DBH 9118 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil or grease in gearboxes, pumps and motors. Its Lx design combines a sealing lip with a dust lip that protects the contact area. With a 30 mm shaft diameter, 47 mm housing and 7 mm height, it is a common size in power transmission equipment. MR Accesorios Industriales supplies it as an official brand.

This item is a DBH 9118 radial shaft seal, identified by its numeric designation. According to the product page data, it has a shaft diameter of 30 mm, a housing diameter of 47 mm and a height of 7.00 mm. The Lx design indicates that it incorporates a main sealing lip and a secondary exclusion lip, intended for environments with dust or dirt. The elastomer and the internal spring are not specified in the record, so they are confirmed against the manufacturer's data sheet at the time of quoting.

It is used in applications with continuous rotation and the need to retain lubricant: gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. It also appears in road and agricultural machinery and in process lines where a 30 mm shaft is common. The dust lip of the Lx design helps maintain sealing integrity when the equipment works in areas with dirt or chips.

For installation, check that the shaft has the right hardness and surface finish, and that the housing is clean and free of burrs. The seal is inserted with a press or support tube, never by striking the lip. Before fitting it, lubricate the lip with the same oil or grease used in the equipment. If the shaft shows wear, consider a repair size or a seal with an offset lip. The final selection depends on speed, temperature and the fluid to be retained.
