The DBH 6691Pol seal is a single-lip radial seal that mounts on the shaft and seals against the housing to retain lubricant and stop dust, water or particles from entering. Due to its dimensions —44.85 mm shaft, 61.42 mm housing and 9.52 mm height— it is used in gearboxes, pumps, electric motors and transmission equipment where bearings and gears must be protected. MR Accesorios Industriales sells it as part of its line of seals and oil seals.

This item is a DBH radial shaft seal with designation 6691Pol, with a shaft diameter of 44.85 mm, housing diameter of 61.42 mm and height of 9.52 mm. The design is Mx-R, a spring-loaded lip configuration that works on rotating shafts and handles moderate peripheral speeds. The sealing lip is made of elastomer and the outer body is metallic, which allows a firm interference fit in the housing. It is a direct replacement part: it is changed when oil leakage or contaminant ingress appears.

Typical applications for a seal of these dimensions are in equipment with shafts between 40 and 50 mm: gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and machine tools. It is also found in chain or belt drives where the shaft passes through a housing and the oil bath must be separated from the environment. In all cases it performs two functions: retaining lubricant inward and blocking dust or moisture outward.

To install it, verify that the shaft has no burrs or deep marks on the sealing surface and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a support tube that pushes on the outer diameter, never on the lip. If the shaft shows wear, consider a repair sleeve. The selection depends on speed, temperature and the type of fluid; with that data the right variant is confirmed.
