The DBH 1366 radial shaft seal is a lip seal that prevents oil or grease leaks and keeps dust and water out of rotating shafts. Its A 433 design combines a main lip with a secondary exclusion lip, making it suitable for equipment with moderate exposure to contaminants. It is press-fitted into the housing and runs on the shaft with a minimal lubricant film. It is a wear part: when leakage appears or the lip hardens, it should be replaced.

This oil seal has a shaft diameter of 15.5 mm, a housing diameter of 25.3 mm and a height of 6.75/8.50 mm. The designation 1366 corresponds to the DBH code and the A 433 design defines the geometry of the lip and the metal body. The double height indicates that the seal can be fitted in cavities of different depths without losing tightness. The lip elastomer is formulated to resist the mineral oils and greases commonly used in power transmission.

It is used in small gearboxes, electric motors, pumps, compressors, fan shafts and transmission equipment. It also appears in agricultural machinery, pneumatic tools and washing equipment where there is water splash. In all these cases it performs two functions: retaining the lubricant inside the assembly and blocking the entry of particles that accelerate wear on bearings and bushings. It is an inexpensive part within the assembly, but its failure can damage much more expensive components.

To select it, check that the shaft and housing diameters match the values on the product page. The shaft must be clean, with no burrs or deep marks in the contact area; a scratched surface destroys the lip within a few hours. Lubricate the lip before mounting and fit the seal with a support tube that presses on the outer diameter, never on the elastomer. If the equipment runs with heavy vibration or temperature, contact us and we will evaluate a higher-resistance alternative.

If you need a nearby size or an equivalent from another brand, send us the original code, the shaft diameter and the housing diameter. With that data we search the DBH line and the other brands we carry. We can also offer you the seal with an exclusion lip or in a more resistant material if the environment is aggressive. The more complete the equipment information, the more accurate the proposal.

MR Accesorios Industriales sells the DBH brand as an official brand. If you want to request an alternative, send the code 1366 by WhatsApp and we will reply with the quote. You can also ask us about oil seals in other sizes, housings, bearings or chains.
