The DBH 9907Pol seal is a single-lip radial seal with a spring, designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that could damage bearings and bushings. With dimensions of 29.85 mm shaft diameter, 47 mm housing and 9.90 mm height, it is press-fitted in crankcases, pumps and gearboxes. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal for your equipment.

This item is a radial shaft seal from the DBH line, identified with the code 9907Pol. Its standard dimensions are: shaft diameter 29.85 mm, housing diameter 47 mm and height 9.90 mm. The Lx-R H design indicates a sealing lip with a spring and a construction that combines a resistant elastomer with a metal reinforcement. It is a precision part that works in direct contact with the shaft, so its correct selection and installation are key to preventing leaks and extending the service life of the internal components.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain transmission systems. In all these equipment, the 9907Pol seal performs the dual function of containing the oil or grease and blocking the entry of external contaminants. It is commonly found in industrial machinery, process equipment and vehicles, where operating conditions demand reliable and long-lasting sealing.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The shaft surface must be free of burrs, scratches or excessive wear; a damaged shaft can ruin the lip in a few hours. During installation, lubricate the lip with the same working oil or grease, insert it perpendicular to the shaft and tap it gently with a tube of suitable diameter until it seats at the bottom of the housing. Avoid hitting the elastomer directly.

If you need an equivalent seal, the most practical thing is to send us the code 9907Pol or the exact dimensions of your shaft and housing. At MR Accesorios Industriales we can look for alternatives within the same DBH brand or other brands we carry, always respecting the dimensions and the type of design. We can also advise you if the mounting space allows variants with an additional lip or special materials for high temperatures.
