The DBH 5140 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 16.50 mm shaft, 30.00 mm housing and 7.00 mm height place it in small-sized equipment, such as electric motors, pumps and compact gearboxes. MR Accesorios Industriales supplies this official brand and advises you to choose the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified with the designation 5140. Its published attributes are: shaft diameter (d) of 16.5 mm, housing diameter (D) of 30 mm and height (h) of 7.00 mm. The indicated design is Lz, which defines the geometry of the lip and the outer body. With these four data you can verify dimensional compatibility before mounting it. If your equipment requires another combination, a neighboring size can be found within the same seal category.

Typical applications for a seal of this size include small electric motors, centrifugal pumps, gear reducers, compressors, fans and power transmission equipment. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing contaminants from entering from the outside. It is also used in machine tools, washing equipment and irrigation systems where the shaft rotates at moderate speeds and the working temperature is stable.

To select and mount correctly, keep in mind that the shaft diameter, housing diameter and height must match those of the seal. The Lz design determines the type of lip and the mounting method, so it is advisable to review the manufacturer's data sheet if you are replacing a seal from another brand. During mounting, lubricate the lip, avoid hitting it and verify it with an installation tool to avoid damaging the sealing edge. A scratched shaft or an oval housing shortens the service life of the seal.
