The DBH 8364 radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts. With dimensions of 17 mm shaft diameter, 40 mm housing and a height of 7.00/12.00 mm, it fits gearboxes, pumps and motors where preventing leaks and contamination is critical. Its A 249-R/B design combines a main lip with a secondary exclusion lip, which improves performance in dusty or dirty environments. It is a common replacement part in industrial maintenance.

This DBH 8364 oil seal has a shaft diameter of 17 mm, a housing diameter of 40 mm and a height of 7.00/12.00 mm. The A 249-R/B design indicates a double-lip configuration: one main sealing lip and one exclusion lip, mounted on a metal body with an outer coating. The sealing lip is made of an elastomer resistant to mineral oils and greases, while the auxiliary lip protects the sealing area from external particles. This combination reduces wear and extends service life under demanding conditions.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases, its function is to retain the lubricant inside the assembly and prevent contaminants such as dust, water or chips from entering. Due to its compact size, it is common in low and medium power equipment where radial space is limited. It is also used as a replacement part in agricultural, textile and transport machinery.

To correctly select this oil seal, verify that the shaft diameter is 17 mm with adequate tolerance and that the 40 mm housing has a smooth, burr-free surface. During assembly, lubricate the lip with the same oil or grease used in the equipment and use an installation tool that presses on the outer edge, never on the lip. Avoid striking the seal and make sure it sits perpendicular to the shaft. If the shaft shows wear, consider a nearby size or a repair sleeve.

If you need an equivalent oil seal or a nearby size, the most practical approach is to send us the code 8364 or the current dimensions (shaft diameter, housing and height). With that data we can look for alternatives in other brands or configurations within the same category. We can also advise you on the most suitable elastomer type or lip design according to the fluid and working conditions. Request a quote via WhatsApp and we will reply shortly.
