The DBH 8101 radial shaft seal is a lip seal that closes off lubricant and blocks dust, water or particles from entering at the point where a shaft rotates inside a housing. With a 120 mm shaft, 140 mm housing and 13 mm height, and Mx design, it is mounted in gearboxes, pumps, motors and power transmission equipment that run with shafts of that diameter. MR Accesorios Industriales carries this official brand.

This oil seal is identified by its designation 8101 and by three dimensions: shaft diameter 120 mm, housing diameter 140 mm and height 13.00 mm. The Mx design defines the geometry of the lip and the metal body, intended for housings that follow that configuration. Before ordering it, compare the three values with the seal you are going to replace: the shaft diameter governs the lip fit and the housing diameter governs the fixing in the housing.

Typical applications of a seal of this size appear in equipment with medium-section transmission shafts: gearboxes, centrifugal pumps, electric motors, mixers and rollers. In all those cases it performs the same function: retaining the oil or grease inside the assembly and preventing contaminants from entering that accelerate wear on bearings and gears. It is also used as a secondary barrier in equipment where there is splashing or a dusty environment.

To select it, check the condition of the shaft surface: a new lip does not seal well on a scratched or worn track. If the shaft is marked, it is often advisable to mount the seal with a slight axial offset or to consider a wear sleeve. Also check the housing, the entry chamfer and that the lip is lubricated before inserting the shaft. The Mx design and the dimensions in the record are the data that define the part.
