The DBH 8387/85 is a radial shaft seal, also called an oil seal, that keeps lubricant inside a housing and keeps contaminants out where a shaft rotates. Its dimensions are 19 mm shaft, 33.30 mm housing and 7.80 mm height, which places it in gearboxes, pumps, motors and similar power transmission assemblies. Because the lip wears against the shaft over time, the seal is a replaceable item: once grease or oil starts escaping, or dirt begins to work its way in, it is time for a new one.

This seal carries the DBH code 8387/85. The size is given as shaft 19 mm, housing 33.30 mm, width 7.80 mm. The Lx designation describes a single-lip seal with a spring, built for rotating shafts that run with lubrication. The elastomeric lip rides on the shaft while the spring holds steady pressure against it, and the outer body is pressed into the housing bore. It is a standard radial sealing component, not a made-to-order part.

Seals of this size show up in gearboxes and reducers, centrifugal pumps, electric motors, compressors and other power transmission equipment. The job is always the same: hold oil or grease in the assembly and block dust, water and particles from reaching the bearing or gearing. Fan, mixer and conveyor shafts in tough environments also use this type of seal.

Before installing, inspect the shaft for burrs, scratches or wear at the contact area, and make sure the housing is clean and not deformed. Lubricate the lip, then seat the seal perpendicular to the shaft. If the shaft has a pronounced groove, consider a seal that positions the lip at a different point. Speed, temperature and the lubricant in use all affect the choice.

For an equivalent, send the code 8387/85 along with the shaft, housing and height measurements and the equipment brand. With that information we can search the DBH line or other brands we supply for a match. A photo of the old seal and the housing also speeds things up; the more detail you provide, the faster we identify the right part.
