DBH 8871 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 8871 and any equivalents.

Part 8871 from DBH is a radial shaft seal, the type of lip seal that keeps oil and grease where they belong and keeps dust and water out of a rotating assembly. Its measurements are 19 mm on the shaft, 35 mm in the housing bore and 7.00 mm of height. Seals in this size range show up in gearboxes, pumps, electric motors and other power transmission equipment. The Lx version pairs a single sealing lip with an outer metal case that presses into the housing. We supply this brand within our seals line and can help you match the size.

Reading the number is simple once you know the layout: the shaft diameter comes first, then the bore, then the width, which here works out to 19 mm, 35 mm and 7.00 mm. The Lx designation tells you the construction: one sealing lip, and a metal case on the outside that is press-fitted into the housing while the lip rides against the rotating shaft. That makes it a straightforward replacement item when the old seal has hardened, worn a groove or started weeping.

You will find a seal of these proportions in gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drive equipment. Its job in each case is the same: hold the lubricant in and keep dust, water and particles out, since those contaminants are what shorten bearing and gear life. Fan and agitator shafts often use the same size as a secondary closure.

Choosing the right seal starts with three checks: shaft size, housing bore and the width you have room for. Beyond the dimensions, the lip and spring material should suit the speed, the operating temperature and the fluid being retained. At installation, clean the bore, put a film of the same oil the equipment uses on the lip, and press the case in squarely without hammering on it. If the shaft is rough or grooved, a repair sleeve or a different size may be the better route.

For an equivalent, send part number 8871 together with the shaft, housing and height figures. A photo of the removed seal or the assembly drawing works just as well. With that information we can point you to the direct alternative in the same brand or another line and put together a quote. The seal does not have to appear in our catalog: we can trace it by size.

DBH forms part of our seals and oil seals offering. If the Lx designation is unclear or you want to weigh it against another design, message us on WhatsApp and we will walk you through it. Quotes are built from the part number plus dimensions, so the more detail you send, the quicker we can reply.
