Part 8852/85 from DBH is a radial shaft lip seal in design A 016, sized for a 25 mm shaft, a 42.50 mm housing bore and an 8 mm width. Seals like this one keep lubricant where it belongs and keep dust and other outside matter from reaching the interior of gearboxes, pumps and motors. MR Industrial Accessories supplies it within its seals and oil seals range.

Reading the code helps when you order. The designation 8852/85 comes from the DBH numbering system and points to one specific size, while A 016 describes the seal itself: a single lip with a spring, built for rotating shafts. The three figures to match are shaft 25 mm, housing 42.50 mm and width 8 mm. Any deviation in one of them changes the fit, so it pays to confirm all three, not just the shaft size.

You will find seals of this size in gearboxes, reducers, centrifugal pumps, electric motors and similar power transmission equipment. In each case the job is the same: hold the oil or grease in and keep contaminants out, which protects bearings and gears. Because the lip runs against the shaft, the seal wears over time. Replacing it whenever the equipment is opened, or as soon as a leak appears, is standard practice.

Before pressing a new seal in, look at the shaft surface for burrs, scores or deep marks across the lip contact band, and make sure the bore is clean and still round. Coat the lip with the same lubricant used in the unit, then seat the seal squarely, applying force on the outer edge rather than on the lip. Shaft speed, working temperature and lubricant type all influence which seal is right for a given application, so check those values with the equipment manufacturer if they are not documented.

If you need a replacement, send part number 8852/85, or the shaft, housing and width measurements together with a photo of the removed seal. The team can search the DBH range as well as other brands supplied and confirm the match against the manufacturer's data. The more details you provide about the equipment, the more precise the recommendation.

Quotes are handled by WhatsApp or email and answered promptly. Include the part number and the quantity required, and note that the team can also suggest equivalents and help you select the correct seal.
