The DBH 8781 radial shaft seal is a lip seal mounted in cylindrical housings to retain lubricant and block the ingress of dust, water or particles in equipment with a rotating shaft. Because of 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 closure 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 a 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 aim is to contain the oil or grease and prevent dirt from entering. In all cases 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, the housing diameter and the available height. The Lx design works with the lip resting on the shaft; therefore the shaft must be polished, free of burrs and 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 runs at high speed or temperature, contact us and we will evaluate the appropriate alternative.

If you need an equivalent, the most practical thing is to send us the code 8781 or the current dimensions (shaft, housing and height) on WhatsApp. With that data we will tell you the next size up or down within the DBH line or other brands we carry. We can also guide you if the seal is mounted on a worn shaft or if the housing has a tolerance different from standard.
