The DBH 9240 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Thanks to its compact dimensions —5.5 mm shaft diameter, 16 mm housing and 8 mm height— it is used in small equipment where space is critical. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a DBH 9240 radial shaft seal, identified by its designation 9240. Its dimensions are shaft (d) 5.5 mm, housing (D) 16 mm and height (h) 8.00 mm. The A 142 design corresponds to the geometry of the lip and the metal body. It is a sealing component that works on the shaft, with the lip resting on the rotating surface and the body seated in the housing cavity. It is made of elastomer with a metal reinforcement to withstand continuous friction.

It is used in applications where oil or grease must be contained and dust, water or particles kept out. It appears in small motors, pumps, gearboxes, power tools, transmission equipment and precision machinery. Also in low-power mechanisms where the shaft rotates at moderate speeds and the cavity is small. It is common in laboratory equipment, instruments and automatic devices that require reliable sealing in little space.

To install it, check that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same service oil or grease before sliding it on, and prevent the spring from coming out. The shaft surface must have adequate roughness and show no wear. When selecting, consider speed, temperature and the fluid to be retained. If the original seal has a different designation, compare dimensions and lip type before replacing it.
