The DBH 8983 is a radial shaft seal that sits in a housing bore and works against a rotating shaft, keeping lubricant in and contaminants out. Its designation reads 75 mm at the shaft, 120 mm at the housing and 13.00 mm in height, with an Lx design. Gearboxes, pumps, motors and other power transmission equipment are the usual homes for a seal of this size. MR Industrial Accessories supplies this brand and can help you match the seal to your application.

Reading the code helps with selection. Part number 8983 identifies the item, and the three figures that follow describe where it fits: shaft 75 mm, housing 120 mm, height 13.00 mm. The Lx designation points to a single lip with a spring, a configuration built for rotating shafts. The lip rides on the shaft while the outer case presses into the bore, and the spring keeps pressure on the lip as it wears and as temperatures shift.

Seals of these dimensions turn up in reducers, centrifugal pumps, electric motors, compressors and similar drive equipment. Whatever the machine, the job is the same: hold oil or grease inside the assembly and block dust, water and particles from getting in. A seal is a wear part, so a lubricant leak, a lip that has hardened, or cuts and deformation on the sealing edge are all signs it is time to replace it.

Before installation, confirm the shaft measures 75 mm, the bore 120 mm and the free height 13.00 mm. Look over the shaft surface for burrs, deep scratches or heavy wear. Lubricate the lip, then seat the seal squarely to the shaft without hammering on it directly. If the equipment runs with strong vibration or high temperature, ask about a different material or design variant.
