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

This 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 is advisable to 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 fixation in the casing.

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

To select it, verify the condition of the shaft surface: a new lip does not seal well on a scratched or worn track. If the shaft has a mark, it is often advisable to install the seal with a slight axial offset or 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 are the data that define the part.
