The DBH 8738 radial shaft seal is a lip seal that mounts on the shaft and inside the housing to contain lubricant and block the entry of dust, water or particles. Its Lx design and dimensions of 12 mm shaft, 25.40 mm housing and 8.00 mm height make it suitable for equipment with small-diameter shafts rotating at moderate speeds. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a DBH radial shaft seal, identified by the designation 8738. Its published attributes are: shaft diameter 12 mm, housing diameter 25.40 mm and height 8.00 mm. The Lx design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The sealing lip runs on the shaft and the outer case is press-fitted into the support. It is a common replacement part in assemblies where oil or grease leaks must be avoided and the interior of the mechanism kept clean.

Typical applications for a seal of these dimensions include small gearboxes, pumps, electric motors, compressors, machine tools and drive equipment. It is also used on fan, mixer and conveyor shafts where the shaft rotates inside a fixed housing. In every case, the seal separates the lubricant from the environment and protects nearby bearings or bushings. If the equipment operates with a lot of dirt or water, it is advisable to verify that the Lx design is suitable for that demand.

To install a radial shaft seal, check the condition of the shaft: no burrs, no wear and with adequate roughness. The housing must be clean and free of deformation. It is recommended to lubricate the lip before inserting it and to use an installation tool that presses on the case, never on the lip. Selection depends on rotation speed, temperature and the type of fluid. If the shaft shows a deep groove, it may be necessary to replace the seal with a size whose lip sits in a different position or to repair the shaft.
