When a gearbox, pump, or motor starts weeping oil around the shaft, the DBH 8365Sil is one of the seals maintenance teams reach for. It is a radial shaft lip seal that presses into the housing and rides against the rotating shaft, keeping lubricant inside and contaminants outside. The size is defined by a 65 mm shaft, a 90 mm housing bore, and a 10 mm height, and the Lx designation tells you it uses a single lip with a spring.

Reading the code is straightforward: 8365Sil is the designation, and the three measurements follow the usual order. Shaft 65 mm, housing 90 mm, width 10 mm. The Lx variant means one sealing lip backed by a spring, a layout intended for rotating shafts that run with lubrication. A metal case holds the elastomer lip in place, and the lip stays in dynamic contact with the shaft while tolerating slight misalignment.

Seals in this size range show up wherever bearings and gears need protection from the surroundings. Typical examples are gearboxes, centrifugal pumps, electric motors, mixers, conveyors, and agricultural or process machinery. The job is always the same: stop grease or oil from escaping and keep dust, water, and particles from getting in and wearing internal parts.

Installation calls for a few checks first. Confirm that the shaft and bore match the catalog values, look for burrs, keyways, or splines that could nick the lip, and make sure the sealing surface is clean and lightly lubricated. Drive the seal in squarely with a proper tool rather than hammering on the lip. On equipment that sees heavy vibration or high temperatures, it is worth reviewing the elastomer compound and the spring before you replace the part.

For a quote, send the complete code, the shaft, housing, and height dimensions, and a photo of the old seal if you have one. With that information we can search the DBH line or other brands we carry for a match. We can also help you pick the right lip design for your lubricant and operating speed.
