The DBH 9012 radial shaft seal is a lip seal that closes the passage of lubricant and blocks the entry of dust, water or particles at the point where a shaft passes through a housing. It is used in gearboxes, pumps, electric motors and transmission equipment that work with 150 mm shafts. MR Accesorios Industriales carries this brand and helps you confirm the size before quoting.

This item is a DBH 9012 radial shaft seal, identified by its designation 9012. It is mounted on a shaft of 150 mm diameter (d), inside a housing of 170 mm (D), with a total height of 12.00 mm (h). The indicated design is Lx, which corresponds to a single-lip seal with metal case and sealing lip. It is a replacement component, not a custom part: it is selected by those three dimensions and by the type of service.

Typical applications for a seal of this size appear in equipment with large-section transmission shafts: reducers and gearboxes, centrifugal and positive displacement pumps, electric motors, rollers and wheel hubs of road or agricultural machinery. In all these cases the seal performs two functions at once: retaining the oil or grease on the inner side and preventing contaminants from entering from the outside.

To install it correctly, verify that the shaft has no burrs, scratches or wear in the contact area, and that the housing is clean and free of impacts. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without tilting it. If the shaft shows a marked wear track, it is advisable to consider a seal with the lip in another position or a wear sleeve. Selection also depends on speed, temperature and fluid, data that must be confirmed against the manufacturer's data sheet.

If you need an equivalent from another brand or the same seal with a different height, send us the code 9012 along with the shaft, housing and height dimensions. With that data we search for the alternative within the lines we carry. We can also review whether the Lx design is suitable for your equipment or whether another type of lip is better for the service.
