The DBH 9842 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With 30 mm shaft diameter, 50 mm housing and 11 mm height, and Lx design, it is used in gearboxes, pumps and motors to retain lubricant and stop the entry of dust. MR Accesorios Industriales carries it as an official brand and helps you confirm the size before requesting a quote.

This item is a radial shaft seal from the DBH brand, part number 9842, with the following dimensions: shaft diameter 30 mm, housing diameter 50 mm and height 11.00 mm. The Lx design indicates the configuration of the lip and the metal body, intended to be press-fitted into the housing and seal against the shaft. It is a standard replacement part within the radial seals and oil seals category, and it is identified by its numeric part number to avoid confusion with similar sizes.

Typical applications for an oil seal of this size appear in equipment with transmission shafts: gearboxes, reducers, centrifugal pumps, electric motors, mixers and machine tools. In all cases it performs the same function: retain the lubricant inside the assembly and prevent contaminants from entering from outside. It is also used as a secondary closure in bearings and housings, where it should be replaced every time the equipment is disassembled so as not to risk a leak.

To install it properly, verify that the shaft and housing diameters match the values on the product page, that the shaft has no burrs or wear in the contact area, and that the housing is clean and free of deformation. Lubricate the lip before inserting it and apply force on the outer ring, never on the lip. If the shaft shows a deep groove, consider a nearby size or an oil seal with the lip in another position so as not to repeat the failure.

If you need an equivalent or a nearby size, send us the part number 9842 along with the shaft, housing and height dimensions, and a photo of the old oil seal if you have it on hand. With that data we review alternatives within the same series or with similar characteristics. We can also guide you if the housing has a shoulder or if the axial space is limited, so as to choose the design that best fits.

At MR Accesorios Industriales we carry the DBH brand as part of our seals and oil seals line. If you already have part number 9842, write to us on WhatsApp and we will send you the quote with the data you need for your maintenance.
