The DBH 9909 seal is a radial lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its designation corresponds to a seal with a 35.00 mm shaft diameter, 56.00 mm housing diameter and a height of 8.00/11.30 mm, with A 308-R AH design. It is used in gearboxes, pumps, electric motors and transmission equipment where the shaft passage must be sealed without losing efficiency or causing leaks.

This item is a DBH 9909 radial shaft seal, identified by its part number 9909. According to the product page data, it has a shaft diameter (d) of 35 mm, a housing diameter (D) of 56 mm and a height (h) of 8.00/11.30 mm. The A 308-R AH design corresponds to a configuration with a sealing lip and a stepped height that allows it to adapt to housings with a shoulder. It is a direct replacement part for equipment that requires that exact size.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission shafts. In all cases, the seal serves two functions: retaining the oil or grease inside the assembly and preventing the entry of dust, water or particles that accelerate wear on bearings and gears. It is a critical part for equipment service life.

To install a DBH 9909 seal, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The seal must enter perpendicular to the shaft, without blows that deform the lip. If the housing has a shoulder, respect the height of 8.00/11.30 mm so that the lip sits in the correct position. If in doubt, consult the manufacturer's technical data sheet.
