The DBH 9842 is a radial shaft seal that keeps oil or grease contained where a rotating shaft passes through a housing. Its dimensions are shaft 30 mm, housing 50 mm, and height 11.00 mm, and it uses the Lx lip and metal body configuration. You will find it in gearboxes, pumps, and motors, where it holds lubricant in and keeps dust out. MR Industrial Accessories supplies this seal and can help you verify the size before you request a quote.

This radial shaft seal carries the DBH brand and part number 9842. The size is given as shaft 30 mm, housing 50 mm, and height 11.00 mm. The Lx designation refers to how the lip and metal case are arranged; the seal presses into the housing and runs against the shaft. It is a standard replacement item in the oil seal and radial seal category, and the numeric part number distinguishes it from seals of similar size.

Seals of this size commonly appear on equipment with transmission shafts: gearboxes, reducers, centrifugal pumps, electric motors, mixers, and machine tools. The job is always the same, which is to keep lubricant inside the assembly and block outside contamination. You will also see it as a secondary closure on bearings and housings, and it should be replaced whenever the equipment is taken apart so that a leak does not develop.

For correct installation, compare the shaft and housing diameters against the values listed for the item, check that the shaft contact area is free of burrs or wear, and make sure the housing is clean and not deformed. Apply lubricant to the lip before fitting, and press on the outer ring rather than the lip. If the shaft has a deep groove, an oil seal with the lip in a different position may be worth considering so the same failure does not return.

When you need an equivalent, send the part number 9842 together with the shaft, housing, and height dimensions, and a photo of the old seal if you have one. With that information we can review options in the same series or with similar characteristics. We can also advise you if the housing has a shoulder or if axial space is tight, so you select the design that fits best.
