The DBH 5123 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 15 mm shaft diameter, 28 mm housing bore and 6 mm height, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a wear part that is replaced during preventive maintenance of pumps, electric motors, gearboxes and similar equipment. MR Accesorios Industriales sells this brand and advises you on choosing the right oil seal.

This item is a radial shaft seal from the DBH line, identified by part number 5123. Its dimensions are 15 mm shaft diameter (d), 28 mm housing bore diameter (D) and 6.00 mm height (h). The Lx design corresponds to a seal with a single sealing lip and metal body, suitable for press fitting into a cylindrical housing. The numeric designation makes it easy to locate in catalogs and maintenance lists. It is a standard replacement part, not a custom component.

Typical applications for a seal of this size include small centrifugal pumps, low-power electric motors, gear reducers, compressors, machine tools and transmission equipment. In every case it performs two functions: preventing oil or grease from leaking out of the bearing and blocking the entry of dust, water or particles. It is also used on fan, mixer and conveyor shafts where there is continuous rotation and a need for reliable sealing.

To install it correctly, check that the shaft measures 15 mm and the housing 28 mm, with no burrs or scratches in the contact area. Lubricate the lip before inserting it and fit the seal with the lip facing the fluid to be retained. The 6.00 mm height must match the housing depth. If the shaft shows wear, consider a seal with an additional lip. The final selection depends on speed, temperature and type of lubricant.
