The DBH 5122 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 28 mm shaft diameter, 47 mm housing diameter and 10 mm height, and an Lz design, it is used in pumps, electric motors, gearboxes and industrial equipment in general. 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 brand, identified with the code 5122. Its dimensions are: shaft diameter (d) 28 mm, housing diameter (D) 47 mm and height (h) 10 mm. The Lz design corresponds to a seal with a sealing lip and a spring that ensures constant contact on the shaft. It is manufactured with elastomers resistant to oils and greases, and its metal structure gives it rigidity to withstand mounting pressure. It is a common replacement part in equipment requiring reliable lubricant retention.

Typical applications of this seal include centrifugal pumps, electric motors, gear reducers, compressors and machine tools. In all these equipment, the seal prevents oil leaks and protects the bearings from contaminant ingress. It is also used on transmission shafts and in process equipment where sealing is critical to maintain lubricant cleanliness and extend component life.

To correctly select this seal, verify that the dimensions match those of the shaft and housing. The shaft diameter must be within the recommended tolerance to avoid leaks or premature wear. The shaft surface must be smooth and free of burrs; a fine surface finish is recommended. When mounting, lubricate the lip with the same oil as the equipment and use a suitable tool to avoid damaging it. If the shaft shows wear, evaluate the possibility of using a seal with an auxiliary lip or a wear sleeve.
