The DBH 5312Pol radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 25 mm shaft, 42 mm housing and 6 mm height, and Lx design, it is a compact, commonly used size in equipment with limited space. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

The DBH 5312Pol is a single-lip radial shaft seal, identified by its designation and by the dimensions shown on the product page: shaft (d) 25 mm, housing (D) 42 mm and height (h) 6.00 mm. The Lx design refers to the seal's construction geometry, with a sealing lip that bears on the shaft and an outer body that fits into the housing. It is a common replacement component, not a custom part: it is selected by those three dimensions and by the type of service.

These seals appear in gearboxes, pumps, electric motors, drive shafts and process equipment where a shaft rotates inside a housing and oil or grease needs to be separated from the environment. They are also used in applications exposed to dust or splashes, provided the lip material is compatible with the fluid and working temperature. In the food, chemical or process industries, it is advisable to verify that compatibility before replacing.

To install a 25 x 42 x 6 mm seal, the shaft must be clean, free of burrs or marks in the contact area, and the housing free of deformation. The lip is lubricated before insertion and the part is seated evenly, without striking the lip or the spring. If the shaft shows wear, a seal of the same size may not seal: in that case a nearby size or a design with an auxiliary lip is evaluated. Selection depends on the fluid, temperature and shaft speed.

If you need an equivalent or a nearby size, send us the code 5312Pol along with the shaft, housing and height dimensions, and a photo or sample of the old seal if you have one. With that data we review alternatives within the same category of seals and radial shaft seals. We can also check whether the Lx design is right for your application or whether another type of lip is better suited.
