The DBH 6121Pol radial shaft seal is a lip seal mounted on a rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 30 mm shaft diameter, 52 mm housing diameter and 7 mm height, and an Mx-R design, it is a common replacement part in gearboxes, pumps and electric motors. MR Accesorios Industriales carries this brand and helps you confirm the size before buying.

This item is a DBH radial shaft seal with the designation 6121Pol, with the following dimensions: shaft diameter (d) 30 mm, housing diameter (D) 52 mm and height (h) 7.00 mm. The indicated design is Mx-R, which corresponds to the construction geometry of the lip and the metal body. It is a single-lip seal, intended for rotating shafts with permanent lubrication. The 6121Pol nomenclature identifies the part within the DBH line and it is best to quote it exactly as is when ordering.

Typical applications for a seal of these dimensions appear in equipment with transmission shafts: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyors. In all cases it performs two functions at once: it prevents oil or grease from leaking out and blocks contaminants from entering from the environment. That is why it is found in preventive maintenance and in repairs where the assembly is disassembled.

To install it properly, check that the shaft has no burrs or wear in the contact area, and that the housing is clean and free of dents. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without deforming it. When selecting a replacement, in addition to the three dimensions, take into account the type of fluid, the working temperature and the shaft speed; if they do not match, the seal may fail prematurely.
