The DBH 9855 radial shaft seal is a lip seal mounted between a rotating shaft and its housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 63 mm shaft diameter, 102 mm housing diameter and 11 mm height place it in medium-sized equipment, where axial space is limited. It is a wear part: when the lip hardens or becomes marked, it starts losing oil and should be replaced before the bearing fails.

This item is a seal from the DBH line, identified by code 9855. Its dimensions are 63 mm shaft diameter (d), 102 mm housing diameter (D) and 11.00 mm height (h). The Lx design corresponds to a single-lip seal with a metal case and elastomer lip, suitable for rotating shafts with grease or oil lubrication. DBH is an official brand that MR carries, so the replacement part is ordered with its exact code and confirmed against the manufacturer's data sheet before shipping.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, mixers, conveyors and power transmission equipment. It is generally found on a bearing cover or at the end of a shaft coming out of a crankcase, where it serves a dual purpose: it prevents lubricant leaks to the outside and blocks the entry of contaminants. It is also used in older or imported machines where the size is not standard and the original part must be replaced.

To install it correctly, check that the shaft has no burrs or wear and that the housing is clean and free of dents. The seal is pressed in with a press or support tube, never by striking the lip, and the edge is lubricated before sliding it on. Selection depends on shaft speed, working temperature and the type of fluid; the Lx design is a general-purpose option, but if there is high pressure or abrasion, another profile should be evaluated. If the shaft is scored, a new seal will not seal: the surface must be repaired or a sleeve used.

If you need an equivalent or a nearby size, send us code 9855 along with the shaft, housing and height dimensions. A photo of the old seal or the assembly drawing also works. With that data we look for alternatives in the same brand or in another line we carry, always respecting the mounting dimensions. The code does not have to be exact: many times the replacement is resolved by size and lip type.

To request a quote for the DBH 9855 seal, write to us on WhatsApp and send us the code or the dimensions. At MR Accesorios Industriales we advise you so you don't buy a part that doesn't fit. If you have doubts about the installation or the condition of the shaft, ask us before installing: a poorly chosen seal will lose oil again within a few hours.
