Description

The DBH 5555 is a radial oil seal that keeps lubricant in and contaminants out where a shaft turns inside a housing. Pressed into the bore, its flexible lip rides on the shaft and tolerates minor misalignment. As a wear part, it is replaced when grease or oil starts to escape or dirt gets in. MR supplies this brand and can help you confirm the size.
Part number 5555 from DBH is a lip seal with these dimensions: shaft 45 mm, housing 65 mm, height 12.00 mm. The design is Lz, a single lip with spring and an outer metal case. Check all three measurements against your shaft and bore before ordering, since a different height or diameter will not seat or seal correctly.
You will find it in gearboxes, pumps, electric motors, transmission assemblies and general machinery where a rotating shaft passes through a housing and the lubricant must stay separated from the surroundings. It also handles dusty or wet conditions by keeping contaminants away from bearings and gears. Though small, it is critical: a failed seal lets lubricant escape and the rest of the assembly wears.
During installation, clean the housing and shaft and check for burrs or marks that could cut the lip. Coat the lip with the same oil or grease used in the equipment. Press the seal in perpendicular to the shaft, applying force on the outer ring with a tube or driver, never on the lip. If the shaft is worn at the contact area, consider a seal with an offset lip.
If 5555 is not the right number, send the dimensions of your seal (shaft, housing and height) or the number marked on the part. We will cross it to an equivalent in DBH or another brand we carry, or to the next larger or smaller size. We can also tell you whether the Lz design suits your application.

Frequently asked questions
- What are the dimensions of the DBH 5555 oil seal?
- Shaft 45 mm, housing 65 mm, height 12.00 mm. It is a single-lip radial seal with spring, Lz design. Verify these against your equipment before ordering.
- How do I know if this oil seal fits my machine?
- Measure the shaft where the lip runs, the housing bore where it is pressed in, and the housing width. If they match 45, 65 and 12 mm, this part number is correct. If not, send us your dimensions and we will look for an equivalent.
- What does the Lz design mean?
- Lz is a radial seal with a single lip and spring, with an outer metal body. It is the common type for rotating shafts with lubricant. If your application involves high pressure or heavy contamination, ask us about other variants.
