The DBH 8452 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and stop dust, water or particles from entering. With dimensions of 27 mm shaft, 45.4 mm housing and a height of 6.6/10.4 mm, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and helps you confirm the size before quoting.

This item is a radial shaft seal from the DBH line, identified by part number 8452. Its dimensions are 27 mm shaft diameter (d), 45.4 mm housing diameter (D) and a height of 6.6/10.4 mm (h), with design A 104. That double height means the lip protrudes from the housing: the 6.6 mm portion fits into the seat and the 10.4 mm corresponds to the assembled unit. The A 104 design defines the geometry of the lip and the metal body, intended for rotating shafts with permanent lubrication.

It is used in equipment where a shaft rotating inside a housing must be sealed: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and agricultural machinery. It also appears in applications exposed to dust or splashes, where the seal keeps lubricant from escaping and contaminants from entering the bearings. It is a wear part: when the lip hardens or the shaft is scored, it starts to leak and must be replaced.

To install it, check that the shaft is clean, free of burrs and grooves, and that the surface where the lip rides has the proper hardness and finish. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it on the side. If the shaft is worn, consider a nearby size or a seal with an auxiliary lip. Selection depends on speed, temperature and lubricant type, data that should be confirmed with the manufacturer's product page.
