The DBH 8733/85 radial shaft seal is a lip seal mounted between a rotating shaft and its housing to retain lubricant and block the ingress of dust, water or particles. With a 9.30 mm shaft diameter, 26.00 mm housing bore and 11.00 mm height, it is a compact size intended for small gearboxes, pumps and reducers where space is limited and sealing cannot be compromised.

This item is a seal with an Lx design, with the dimensions shown in its designation: 9.30 mm shaft diameter (d), 26.00 mm housing bore diameter (D) and 11.00 mm height (h). The Lx design corresponds to a single lip seal with a metal case and an elastomeric sealing lip, supported on the shaft by interference. The 11 mm height gives it enough body to seat firmly in the housing without deforming when pressed. It is a part in the radial seals and oil seals category that MR Accesorios Industriales sells as official brand DBH.

Typical applications for a seal of this size appear in equipment with small-diameter shafts: low-power electric motors, small centrifugal pumps, gearboxes and compact gear cases, compressors, machine tools and drive equipment where oil or grease must be retained and external contamination prevented. It is also used on fan, agitator and light conveyor shafts. In all cases it performs the same function: separating two environments, one lubricated and one exposed, with the shaft rotating continuously or intermittently.

To install it correctly, verify that the shaft and housing bore diameters match the values in the data sheet and that the shaft surface is polished and free of burrs: a lip running on a scratched surface wears quickly and loses sealing. Lubricate the lip before inserting it, place the seal perpendicular to the shaft and push it with a tube or shim that bears on the outer edge, never on the lip. If the equipment operates at high temperature or speed, or with exposure to solvents, consult us about the lip compound before requesting a quote.

If you need an equivalent or a nearby size, send us the code 8733/85 together with the shaft and housing bore diameters you have measured on the equipment. With that data we search within the DBH line and other brands we carry for the closest option, and we confirm whether the housing needs modification or if it fits directly. We can also evaluate design variants if the original seal is no longer available.
