The DBH 9123 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 36 mm shaft diameter, 48 mm housing diameter and 8 mm height place it in the range of compact seals for medium-sized equipment. It is a wear part: when the lip hardens or becomes marked, oil loss begins and it should be replaced in time.

This item is a DBH brand oil seal, identified by the code 9123. Its dimensions are 36.00 mm shaft diameter (d), 48.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a seal with a single sealing lip and an outer metal body, designed for press-fit mounting in the housing. The lip runs on the shaft and is the surface that performs the dynamic sealing.

It is used in gearboxes, pumps, electric motors, rollers and power transmission equipment where there is a shaft rotating inside a housing with lubricant. It also appears in applications exposed to dust or water, where the seal serves a dual purpose: it retains the oil inside and blocks the entry of contaminants from outside. It is a small but critical part: if it fails, the equipment loses lubricant and the wear of bearings and gears accelerates.

To install it, check that the housing and shaft are clean, free of burrs or marks that could cut the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, using a tube or socket that rests on the metal edge, never on the lip. If the shaft is worn or has a marked groove, the new seal may not seal: in that case it is advisable to evaluate a wear sleeve or a different shaft size.

If you need an equivalent or a nearby size, send us the code 9123 or the current dimensions (shaft diameter, housing diameter and height) and the type of equipment where it is mounted. With that we review alternatives within the DBH line or from other brands we carry, always respecting the mounting dimensions. If space allows, sometimes you can move to a seal with an additional lip or a design with greater dust protection.
