The DBH 8852/85 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil, grease or contaminants in gearboxes, pumps and motors. With a 25 mm shaft diameter, 42.50 mm housing diameter and 8 mm height, and design A 016, it is a commonly used size in power transmission equipment. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

This item is a DBH radial shaft seal, identified with the designation 8852/85. Its dimensions are shaft (d) 25 mm, housing (D) 42.50 mm and height (h) 8.00 mm, with a design A 016. Design A 016 corresponds to a single-lip seal with spring, intended for rotating shafts where the goal is to contain lubricant and prevent the entry of dust. The nomenclature 8852/85 follows the brand's coding system and allows the part to be located without ambiguity.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment in general. In all cases it serves to retain lubricant inside the assembly and block the entry of external particles, extending the service life of bearings and gears. It is a wear part: it should be replaced whenever the equipment is disassembled or at the slightest sign of leakage.

For installation, check that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before seating the seal, and insert it perpendicularly, without hitting the lip. The selection of a radial shaft seal depends on shaft speed, operating temperature and the type of lubricant; if those data are not defined, they should be checked with the equipment manufacturer.
