A lip seal in the DBH line, code 8347, built to run against a rotating shaft. It keeps lubricant where it belongs and blocks dust, water and particles from reaching bearings and bushings. The seal presses into the housing bore and rides on the shaft, forming a dynamic barrier in industrial equipment.

The designation tells you the three values you need before ordering: shaft 20 mm, housing bore 30 mm, height 7.00 mm. The Lx configuration means a single sealing lip combined with a metal case, a setup used where oil or grease retention is the goal. Because the code 8347 is short and specific, it is easy to find on a maintenance list or in a catalog.

You will find seals of this type in gearboxes, pumps, electric motors, compressors and power transmission assemblies. Their job is twofold: hold lubricant in and keep contaminants out, which protects the bearings behind them. Machine tools, conveyors and hydraulic systems with continuously rotating shafts are common applications, as are automotive and general industrial setups that call for simple, efficient sealing.

Correct selection starts with matching all three dimensions to the shaft and housing. The shaft surface should be ground and free of burrs, since a rough finish wears the lip faster. Lubricate the lip with the same oil or grease the equipment uses, and fit the seal with an installation sleeve so the lip does not twist. When replacing an existing seal, check the design and lip material as well.
