The DBH 9101 is a single-lip radial shaft seal that fits a 30 mm shaft and a 42 mm housing, with a 10 mm height. Its job is to keep lubricant in and contaminants out of gearboxes, pumps, motors and similar equipment. The design combines a spring-loaded elastomer lip with a metal outer case, so it holds tight in the housing and maintains contact on the shaft. When a seal wears out, replacing it with the correct size restores the protection your bearings need.

The code Lx tells you this is a single sealing lip with a spring. The lip, usually an elastomer, rides against the shaft while the spring keeps steady pressure on it. A metal outer body presses into the housing bore to lock the seal in place. This layout works well on shafts turning at moderate speeds where lubrication is continuous. The dimensions are: shaft 30.00 mm (d), housing 42.00 mm (D) and width 10.00 mm (h).

You will find this seal in gearboxes, centrifugal pumps, electric motors, speed reducers and transmission units. It also shows up in machine tools, conveyors and agricultural machinery. In every case, the seal stops oil or grease from escaping and blocks dust, water or particles from reaching the bearings. If your shaft measures 30 mm and your housing bore is 42 mm, the DBH 9101 is a direct replacement for a worn seal and brings the assembly back to proper sealing.

Before installing, inspect the shaft for burrs or wear in the contact zone; a rough surface will cut the lip short. Put a little lubricant on the lip, then press the seal in with a proper tool, keeping force even on the outer diameter. The 10 mm height should end up flush or slightly recessed, depending on how the housing is made. For equipment that sees high vibration or temperature, a lip material with better resistance may be worth considering.
