For maintenance and purchasing teams, the DBH 9123 radial shaft seal is a compact lip seal that presses into a housing and runs against a rotating shaft. Its job is to hold lubricant in and keep dust, water, and particles out. With a 36 mm shaft, 48 mm housing, and 8 mm height, it fits many medium-sized power transmission and pump applications. Because it is a wear part, a hardened or scored lip will start to leak oil, so timely replacement matters.

The DBH 9123 carries a single sealing lip and an outer metal case, which is the Lx design. The lip contacts the shaft and does the dynamic sealing, while the metal case holds the seal firmly in the housing bore. The code 9123 identifies this size within the DBH line. Always confirm the three dimensions on the old seal with a caliper: shaft 36.00 mm, housing 48.00 mm, height 8.00 mm.

Typical installations include gearboxes, pumps, electric motors, rollers, and other power transmission equipment where a shaft turns inside a lubricated housing. In dirty or wet environments, the same seal also blocks contaminants from entering. A small leak may seem minor, but losing lubricant can speed up bearing and gear wear, so replacing the seal before the lip is badly damaged is good practice.

During installation, clean the housing bore and shaft, and remove any burrs or marks that could cut the lip. Lubricate the lip with the same oil or grease used in the equipment. Press the seal in squarely using a tube or socket that contacts the metal case, never the lip. If the shaft has a deep groove or is worn, a new seal may not seal properly; in that case, consider a wear sleeve or a different shaft size.

To quote a replacement or equivalent, send the code 9123 or the current dimensions—shaft, housing, and height—along with the equipment type. We can review options within the DBH line and from other brands we supply, keeping the mounting dimensions the same. Where space allows, a seal with an extra lip or more dust protection may be an option.
