A radial shaft seal from the DBH line, the 8787C/AR keeps lubricant where it belongs and keeps dust, water and particles out of rotating equipment. Its dimensions are 59 mm at the shaft, 85.60 mm at the housing bore and 15.00 mm in height, and it follows the A 226 design. Maintenance teams use it on gearboxes, pumps, motors and similar machinery, where a leaking seal puts bearings and gears at risk.

Reading the designation helps you match a replacement quickly: 8787C/AR points to one specific size and construction, so a cross-reference is straightforward once you confirm the three measurements. The A 226 design is a single lip with a spring, a configuration meant for rotating shafts that run with lubrication. Elastomer construction gives the seal resistance to the oils and greases normally found in industrial drives.

Where does this seal fit? Gearboxes and speed reducers, centrifugal pumps, electric motors and power transmission assemblies all rely on it to hold lubricant in and contamination out. It also appears at the shaft exit of rollers and split plummer block housings, a point where sealing has to work properly. The 59 x 85.60 x 15 mm size is a common one in industry, which makes replacement easier to source.

Installation is simple if you prepare the surfaces first. The shaft and the housing bore should be clean and free of burrs, nicks or machining marks that could cut the lip; a damaged lip will leak from day one. Coat the lip with the same oil or grease the equipment uses, then press the seal in squarely so the full 15.00 mm height seats correctly. When choosing a seal, take shaft speed, operating temperature and the fluid being retained into account. If the old seal wore unevenly, inspect the bearing and check that the housing is concentric before fitting a new one.

Alternatives from other brands are available, and we will help you pick the right one for the application. Details about the equipment, rotation speed and temperature make the recommendation more precise.
