The DBH 9056 radial shaft seal is a lip seal that mounts on a 9 mm shaft and seals against a 30 mm housing, with a 7 mm height. Its function is to retain the lubricant inside the assembly and stop the entry of dust, water or particles, running on the moving shaft. It is used in gearboxes, pumps, electric motors and transmission equipment where space is limited and a reliable seal is needed.

The DBH 9056 has the dimensions shown in its designation: 9 mm shaft, 30 mm housing and 7 mm height. The Lx design corresponds to a single-lip seal with a spring, designed for rotating shafts with lubrication. The elastomeric lip runs on the shaft and the spring maintains contact pressure; the outer body fits into the housing. It is a wear component: when the lip hardens or becomes marked, it starts to lose oil.

These seals appear in equipment where the shaft is thin and the housing does not leave much room: small electric motors, centrifugal pumps, gearboxes, fans, machine tools and power transmission equipment. They are also used in agro-industrial applications and general maintenance, where replacing the seal prevents lubricant from escaping and dust from entering the bearing or bushing.

To choose correctly, check that the shaft diameter, housing diameter and height match the original seal. Check the condition of the shaft surface: if it has burrs, wear or a marked track, the new lip will not seal. When installing, lubricate the lip, seat the seal straight and tap on the outer edge, never on the lip. If the shaft is damaged, consider a wear sleeve or an alternative size.
