The DBH 9180Pol is a radial shaft seal with a single lip and spring, sized for a 125 mm shaft, a 150 mm housing bore and a 15 mm height. It presses into the housing and rides on the rotating shaft, holding lubricant in and keeping dust, water and particles out. The design is Mx-R-AH: a flexible sealing lip backed by a spring, carried in a rigid mounting body.

Dimensions read as shaft 125 mm, housing 150 mm, height 15 mm. Those three figures decide whether the seal fits: the shaft diameter is measured on the wear track, the housing diameter in the bore, and the height against the cavity depth. The Mx-R-AH designation tells you the lip is spring-loaded and the body is made to be press-fitted. The lip contacts the shaft, the spring keeps pressure on it, and the body stays fixed in the housing.

You will find this size on medium-sized transmission equipment: gearboxes, centrifugal pumps, electric motors, rollers and similar power transmission assemblies. It also turns up in mixers, compressors and process machinery where a shaft passes out of a lubricated housing. Its job is twofold, keeping oil or grease from escaping and stopping outside contamination from reaching bearings or gears. Treat it as a wear part and inspect it whenever leaks or unusual noise appear.

Before ordering, confirm the three dimensions against the actual shaft, bore and cavity. A scored or stepped shaft will not let a new lip seal correctly. The shaft surface should be ground, and both lip and shaft need lubrication before assembly. Seat the seal square with a flat-faced driver, never hammering the lip. If the housing has burrs or a shallow chamfer, clean or correct it first so the seal enters without damage.

To get a quote for code 9180Pol, send the shaft, housing and height measurements, or a photo of the old seal, or the code stamped on its body. With that we can locate an equivalent in the same series or from another brand while keeping the Mx-R-AH design. If the shaft is worn, we can review lip or mounting options so the seal runs on a sound surface. MR Industrial Accessories LLC supplies the DBH brand and serves customers across the United States and in several Latin American countries.
