The DBH 9004 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With 120 mm shaft diameter, 160 mm housing and 12 mm height, this size covers transmission equipment and heavy machinery. MR Accesorios Industriales supplies the DBH brand as part of its line of seals and oil seals.

The DBH 9004 is a radial shaft seal with Lx design, with the nominal dimensions shown in its designation: 120.00 mm shaft diameter (d), 160.00 mm housing diameter (D) and 12.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and metal body, intended to be press-fitted into the housing with the lip resting on the rotating shaft. It is a standard replacement part within the seals and oil seals category.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where there is a shaft rotating inside a housing and it is necessary to contain the oil or grease. It also appears in applications exposed to dust or splashes, where the seal acts as a barrier. Because of its size, it is common in medium-sized industrial machinery and in continuous process equipment.

To select it, check that the shaft diameter, housing diameter and height match those of the DBH 9004. The condition of the shaft surface is key: a scratched or worn shaft means the lip does not seal well, even if the size is correct. During installation, lubricate the lip before inserting it and rest the part perpendicular to the shaft so as not to damage the seal. If the housing has burrs, it is advisable to smooth it before fitting the seal.

To quote an equivalent, send us the part number engraved on the old seal, the shaft and housing dimensions, and a photo of the part. With that data we can locate the alternative within the DBH line or other brands we supply. The drawing or the data sheet of the equipment where it is mounted also helps, especially when the original seal has no legible identification.
