The DBH 6691Pol oil seal is a single-lip radial seal that mounts on the shaft and closes against the housing to retain lubricant and stop the ingress of dust, water or particles. 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 supplies it as part of its seals and oil seals line.

This item is a DBH radial shaft seal with designation 6691Pol, with a 44.85 mm shaft, 61.42 mm housing and 9.52 mm height. The design is Mx-R, a lip configuration with a spring that works on rotating shafts and supports 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 replaced when oil leakage or contaminant ingress appears.

Typical applications for an oil 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 casing 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.

For assembly, verify that the shaft has no burrs or deep marks on the sealing track 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 or a nearby size. Selection depends on speed, temperature and the type of fluid; with that data the appropriate variant is confirmed.
