For rotating shafts that need reliable sealing, the DBH 9909 radial lip seal keeps lubricant in and contaminants out. Its code covers a 35.00 mm shaft, a 56.00 mm housing bore and a height of 8.00/11.30 mm, with the A 308-R AH profile. Gearboxes, pumps, electric motors and similar transmission equipment are common places to find it.
The DBH 9909 is identified by part number 9909. Its dimensions are: shaft 35 mm, housing 56 mm, height 8.00/11.30 mm. The A 308-R AH configuration indicates a sealing lip and a stepped height that fits housings with a shoulder. This makes it a direct replacement when the original seal matches those figures.
Seals of this size appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission shafts. They perform two jobs: holding oil or grease inside the assembly and blocking dust, water or particles that would otherwise speed up wear on bearings and gears. That dual role makes the seal important for equipment service life.
When installing a DBH 9909, make sure the shaft and housing are clean and free of burrs or scratches. Apply the same oil or grease used in the equipment to the lip before pressing it in. Insert the seal squarely to the shaft, without hammer blows that could distort the lip. If the housing has a shoulder, observe the 8.00/11.30 mm height so the lip seats correctly. Consult the manufacturer's technical data sheet if anything is unclear.
If you are looking for an equivalent, send part number 9909 or the shaft, housing and height dimensions. MR works with the DBH line and can point you to the reference that suits your equipment. We can also help identify a seal from a sample or from caliper measurements.

Frequently asked questions
- What are the dimensions of the DBH 9909 seal?
- It fits a 35 mm shaft and a 56 mm housing bore, with a height of 8.00/11.30 mm. The design is A 308-R AH. These figures come from the manufacturer's data sheet and determine whether the seal matches your shaft and housing.
- How do I know if this seal is compatible with my equipment?
- Measure the original seal: shaft diameter, housing diameter and height. If they read 35 mm, 56 mm and 8.00/11.30 mm, the DBH 9909 is the correct replacement. If you are unsure, send a photo or caliper readings and we will help you confirm it.
