The DBH 9333 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Due to its dimensions —11 mm shaft, 30 mm housing and 7 mm height— it is used in compact equipment: small pumps, electric motors, light reducers and auxiliary drives. Its Lx design corresponds to a seal with a single sealing lip and metal body, suitable for shafts rotating at moderate speeds.

The DBH 9333 is a radial shaft seal from the DBH line, with the following dimensions: shaft diameter 11 mm, housing diameter 30 mm and height 7.00 mm. The Lx design indicates a single-lip seal with metal case and elastomeric sealing lip, designed for rotating shafts with grease or oil lubrication. These dimensions are those given in the manufacturer's data sheet and are the ones you must verify before ordering: the seal is identified by these three values, not by the code alone.

Typical applications for a seal of this size are small centrifugal pumps, low-power electric motors, compact gear reducers, auxiliary transmission boxes, fans and laboratory or food industry equipment. In all cases it performs the same function: keeping the lubricant inside the assembly and preventing contaminants from entering from outside. It is also used as a secondary closure in small-shaft bearings, where radial space is limited.

To install it properly, keep three things in mind. First, the housing must be clean, free of burrs and with the correct diameter and depth; the seal is inserted with a press or flat shim, never by hitting the lip. Second, the shaft must not have splines or wear in the contact area: a deep mark ruins the seal. Third, lubricate the lip with the same grease or oil as the equipment before assembling. If the shaft rotates at high speed or there is high pressure, it is advisable to evaluate another seal design.

If you need a seal equivalent to the 9333, send us the full code and the shaft, housing and height dimensions. With that data we search the DBH line or another brand we carry for the seal with the same dimensions. We also confirm whether the Lx design is suitable for your application or indicate a seal with double lip, dust guard or spring. The more data you give us, the more accurate the search.
