DBH 9855 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 9855 and any equivalents.

The DBH 9855 is a radial shaft lip seal that sits between a rotating shaft and its housing, holding lubricant in and keeping dust, water and particles out. With a 63 mm shaft, 102 mm housing bore and 11 mm width, it fits medium-sized assemblies where axial room is tight. Treat it as a wear item: once the lip hardens or shows marks, oil starts escaping and the seal should be changed before the bearing is affected.

The part belongs to the DBH line and carries code 9855. Reading the designation: shaft 63 mm (d), housing 102 mm (D), height 11.00 mm (h). The Lx configuration is a single-lip seal with a metal case and elastomer lip, meant for rotating shafts running on grease or oil. DBH is one of the brands we supply, so the replacement is ordered under its exact code and checked against the manufacturer's data sheet before it ships.

Seals in this size range turn up in gearboxes, centrifugal pumps, mixers, conveyors and power transmission equipment. You will usually find one on a bearing cover or where a shaft exits a crankcase. Its job is twofold: no lubricant escaping to the outside, no contaminants working their way in. It also solves the problem of older or imported machines whose seal size falls outside common standards and has to be matched to the original.

Installation calls for a shaft free of burrs and wear, plus a housing that is clean and undented. Press the seal in with a press or a support tube, never by hitting the lip, and lubricate the edge before sliding it into place. Choosing the right profile depends on shaft speed, operating temperature and the fluid involved. Lx is the general-purpose option; where pressure or abrasion is present, evaluate a different profile. A scored shaft will not seal no matter what you install, so repair the surface or fit a sleeve.

For an equivalent, send code 9855 together with the shaft, housing and height measurements. A photo of the old seal or the assembly drawing works too. With that information we look at options in the same brand or in another line we carry, keeping the mounting dimensions intact. The code does not have to match exactly, since size and lip type often resolve the replacement.

To get a quote on the DBH 9855, message us on WhatsApp with the code or the dimensions. We help you avoid buying a part that will not fit. If you are unsure about installation or the condition of the shaft, ask before fitting it, because a seal chosen incorrectly will start losing oil again within hours.
