The DBH 5138Vit is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With a 15.00 mm shaft, 30.00 mm housing and 7.00 mm height, it fits small assemblies where space is tight and speeds are often high. As a wear part, it is replaced when oil loss or dirt ingress appears.
This seal belongs to the DBH line and carries the code 5138Vit. Its Lx design means a single lip with spring and a metal outer case, press-fitted into a machined cavity. The elastomer lip rides on the shaft, and the internal spring maintains contact. The published dimensions are 15 mm shaft, 30 mm housing and 7.00 mm height.
You will find it in small gearboxes, low-power electric motors, centrifugal pumps, fans, mixers and power transmission units where oil or grease must be separated from the environment. It also appears in machine tools, roller shafts and similar continuous-rotation applications. In every case it performs two jobs: retaining lubricant inside and blocking particles that would accelerate bearing and gear wear.
When selecting, confirm that the shaft and housing diameters match the data sheet and that the cavity width accepts the 7.00 mm height. The shaft surface should be ground and free of burrs; a deep scratch or mark can ruin the lip in a few hours. Lubricate the lip with the same oil or grease used in the equipment before mounting, and press the seal perpendicular to the shaft using a tube or socket that contacts the outer ring, never the lip. If the shaft has play or pitting, consider replacing the shaft or using a wear sleeve.
To request a quote for the 5138Vit, send the complete code along with the shaft, housing and height dimensions. With that data we can look for an equivalent in the same DBH line or in another brand we carry. We can also advise if the original seal uses a different design, such as double lip or with dust guard, if you indicate the application and working conditions.

Frequently asked questions
- What are the dimensions of the DBH 5138Vit oil seal?
- The 5138Vit has a 15 mm shaft diameter, 30 mm housing diameter and 7.00 mm height. These are the three dimensions to check against your original seal.
- How do I know if this oil seal fits my equipment?
- Measure the shaft diameter where the lip runs, the cavity diameter where the seal is housed and the cavity width. If they are 15, 30 and 7.00 mm, the 5138Vit is compatible.
- What does the Lx design mean on this oil seal?
- Lx indicates a single lip seal with spring and metal body, designed for press-fitting into a housing. It is common in small equipment. If your application needs a double lip or dust guard, let us know and we will look for the variant.
