The DBH 9542 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns. Its size—40 mm shaft, 59 mm housing, 9 mm width—fits medium-duty shafts. Pressed into the housing, its flexible lip rides on the shaft to maintain a dynamic seal. This kind of part is essential for shielding bearings and gears from dust, water, and chips.

This oil seal follows the Lx design and measures 40 mm at the shaft, 59 mm at the housing, and 9 mm in width. The elastomer lip resists oils and greases, forming a dependable barrier against leaks and particles. Its metal outer case holds firmly in the bore and takes normal installation pressure. It is a standard choice for moderate-speed shafts that need reliable sealing.

You will find it in pumps, electric motors, gearboxes, conveyor rollers, and agricultural or road equipment. It also appears in power transmission systems where bearings and gears must stay free of contaminants. The 40x59x9 mm size is common across many industrial shafts, so it often matches equipment from well-known manufacturers. As a wear item, it should be replaced when it hardens, cracks, or loses elasticity.

When choosing a seal, check that the shaft diameter is within tolerance and that the housing is free of burrs or excessive wear. At installation, lubricate the lip with the same oil or grease used in the machine and use a tool that presses on the metal case—never on the lip. Do not strike the seal directly. If the shaft shows a deep groove, consider replacing it or positioning the lip slightly differently.
