The DBH 9233 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. Its dimensions of 41.20 mm shaft, 50.80 mm housing and 4.76 mm height place it in applications with limited space, where the Ms design provides a compact section and a firm contact lip. It is used in pumps, electric motors, gearboxes and power transmission equipment operating with shafts of that diameter.

The DBH 9233 is a single-lip radial shaft seal, identified by its numeric designation and by the dimensions listed on its product page: 41.20 mm shaft diameter, 50.80 mm housing diameter and 4.76 mm height. The Ms design corresponds to a thin-section configuration, intended for tight axial spaces where a standard-profile seal does not fit. The sealing lip runs on the shaft and the outer case seats in the housing, creating the static and dynamic seal.

This type of seal is used in rotating equipment that needs to contain oil or grease while protecting the bearings from the environment. It appears in centrifugal pumps, electric motors, gearboxes, compressors, mixers and machine tools. It is also found in applications where the shaft rotates at moderate speeds and the operating temperature is not extreme, provided the lip material is compatible with the fluid and the service conditions.

For installation, check that the shaft diameter and the housing diameter match the values on the product page and that the shaft surface is clean, free of burrs or marks that could damage the lip. Lubricate the lip before inserting it and apply force on the outer ring, never on the lip. If the seal replaces another one, compare the design and the height: a difference of a few tenths can prevent correct seating or leave the lip off the track.

If you need a nearby size or an equivalent, send us the code 9233 or the shaft, housing and height dimensions, along with the type of fluid and operating temperature. With that data we can look for an alternative within the DBH line or from other brands we carry. It is also helpful to indicate the equipment and the position where it is mounted, because that helps define the most suitable lip design and material.
