The DBH 8781 radial shaft seal is a lip seal that mounts in cylindrical housings to retain lubricant and block the entry of dust, water or particles in equipment with a rotating shaft. Due to its compact size of 13 mm shaft, 25 mm housing and 7 mm height, it is used in pumps, small electric motors, gear reducers, gearboxes and transmission mechanisms where space is limited and a reliable seal is required.

This item is a DBH 8781 radial shaft seal with the following dimensions: shaft diameter 13 mm, housing diameter 25 mm and height 7.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The designation 8781 identifies the exact size within the DBH line, so if you need to replace a worn seal, this code lets you order the same size without ambiguity.

Typical applications for a seal of this size are small centrifugal pumps, low-power electric motors, gear reducers and compact gearboxes, compressors, machine tools and transmission equipment. It also appears on fan, mixer and conveyor shafts where the goal is to contain oil or grease and prevent dirt from entering. In every case it is advisable to verify that the shaft and housing are in good condition before mounting.

To select this seal correctly, take into account the shaft diameter, housing diameter and available height. The Lx design works with the lip resting on the shaft; therefore the shaft must be polished, without burrs or marks, and the housing clean and free of deformation. During installation, lubricate the lip and use a tool that does not damage it. If the equipment operates at high speed or temperature, consult us and we will evaluate the appropriate alternative.

If you need an equivalent or a nearby size, the most practical thing is to send us code 8781 or your current dimensions (shaft, housing and height) via WhatsApp. With that data we check whether there is an immediate larger or smaller size within the DBH line or other brands we supply. We can also advise you if the seal is mounted on a worn shaft or if the housing has a tolerance different from standard.
