The DBH 9808 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its dimensions are 32.00 mm shaft diameter, 47.00 mm housing diameter and 9.50 mm height, and it uses the A 080 design: a single lip with spring. MR Industrial Accessories LLC supplies this brand to maintenance and purchasing teams across the United States and in several Latin American countries.

The code 9808 identifies this seal within the DBH line. In the size designation, the shaft diameter (d) is 32.00 mm, the housing diameter (D) is 47.00 mm and the height (h) is 9.50 mm. The A 080 design refers to a single lip with a spring, a common configuration for rotating shafts. The elastomer lip and the metal case work as a pair: the lip holds the lubricant against the shaft while the case holds the seal firmly in the housing. This is a wear part, so it is normally replaced when a leak shows up or during scheduled preventive maintenance.

Seals like the 9808 are found in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. The seal sits in a cover or housing with the lip running on the shaft, keeping oil on one side and the environment on the other. Rollers, mixers and industrial or agricultural machinery that have a shaft passing through a wall also use this type of seal. Where dust or water is present, the same lip helps exclude those contaminants.

Installation matters as much as the part number. Check that the shaft is free of burrs and marks and that the sealing surface is polished. Lubricate the lip before sliding it over the shaft, and press with an installation tube on the outer diameter only, never on the lip. The housing bore must give a firm fit; a damaged bore will not seal correctly. When selecting a replacement, consider shaft speed, operating temperature and the lubricant in use.

If the old seal carries a different designation, send us the code and the shaft and housing dimensions. We can suggest an equivalent with the same dimensions. To request a quote for the DBH 9808, contact us by WhatsApp or email with the part number and we will reply promptly.
