The DBH 8259 radial shaft seal is a lip seal designed for 15 mm rotating shafts, with a 25.50 mm housing bore and 7.00 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified by the code 8259. Its dimensions are: shaft diameter 15 mm, housing bore 25.50 mm and height 7.00 mm. The Lx design corresponds to a single lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip presses against the shaft and creates a dynamic seal, while the outer body holds the part firmly in the housing. It is a compact solution for tight spaces.

Typical applications for a seal of this size include small electric motors, centrifugal pumps, speed reducers, gearboxes, compressors and belt or chain drive equipment. It is also used in machine tools, washing equipment and irrigation systems. In all cases, its purpose is to protect the bearings and prevent oil or grease leaks. If the equipment operates with a lot of dirt or water, it is advisable to verify that the lip material is suitable for those conditions.

To install a seal, check the condition of the shaft and housing: there must be no burrs, scratches or wear. The shaft must have hardness and roughness compatible with the lip, and the housing must be clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a tube or press that applies pressure on the outer diameter, never on the lip. If the previous seal failed, check alignment and concentricity before installing the new one.
