The DBH 5138 radial shaft seal is a lip seal mounted in a component housing to retain lubricant and block the entry of dust, water or particles. With dimensions of 15 mm shaft, 30 mm housing and 7 mm height, and Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales offers it as part of its line of seals and oil seals for industrial maintenance.

This item is a radial shaft seal from the DBH brand, identified with the code 5138. Its nominal dimensions are 15.00 mm shaft diameter (d), 30.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design corresponds to a single lip configuration with spring, intended for rotating shafts with lubrication. These dimensions are the ones you need to verify against the housing and the shaft before replacing a worn part.

Seals of this type are used in equipment where oil or grease must be contained and external contamination prevented. They appear in gearboxes, centrifugal pumps, electric motors, compressors, mixers and conveyors. In the food, chemical or process industries, the selection of the lip material and the elastomer depends on the fluid and the working temperature, so it is advisable to confirm those data with the manufacturer or with the technical supplier.

To mount a radial shaft seal, the shaft must be clean, free of burrs or marks, and the housing must have the appropriate chamfer so as not to damage the lip. It is recommended to lubricate the lip with the same oil or grease as the equipment before inserting it, and to use a mandrel or support tube to seat it under pressure evenly. Shaft eccentricity and bearing play influence the service life of the seal, so it is advisable to check those points during assembly.
