The DBH 9151 is a radial shaft seal that sits in the housing bore and rides against the rotating shaft. It keeps lubricant where it belongs and keeps dust, water and other particles out. With a 30 mm shaft, 70 mm housing bore and 10 mm height, and an Lx lip profile, it fits industrial equipment where the seal has to hold up and be easy to swap out. MR supplies it within its seals and oil seal range.

The part number breaks down simply: DBH is the brand, 9151 is the item reference, and the three figures describe the fit. Shaft 30 mm, housing 70 mm, width 10 mm. The Lx designation tells you it is a single lip with a spring, built for rotating shafts that run with oil or grease. The elastomer lip contacts the shaft while the metal outer case presses into the housing bore, which is what creates the seal on both sides.

You will find seals like this one in gearboxes, pumps, electric motors, conveyor rollers and other power transmission assemblies. They do two jobs at once: they stop oil or grease from escaping, and they keep contaminants away from bearings and gears. In a plant, that makes the seal a wear item that gets replaced on a scheduled maintenance stop or when a leak shows up.

Choosing the right seal comes down to three measurements first: shaft diameter, housing bore and height. Beyond that, look at how fast the shaft turns, the temperature it sees and the lubricant in use. An Lx lip is the right call for a rotating shaft with oil or grease lubrication. During installation, clean the bore, put a light film of lubricant on the lip and seat the seal with a proper driver so the lip is not nicked or rolled.
