When a rotating shaft needs to keep lubricant in and contaminants out, a radial shaft seal like the DBH 5949 does the job. This lip seal, with its Mz design and metric dimensions, fits small shafts and medium-section housings. It is commonly found in gearboxes, pumps, motors, and transmission equipment where bearing protection is critical.
The DBH 5949 is a single-lip radial shaft seal built for permanent lubrication. Its dimensions are shaft 29.59 mm, housing 56.57 mm, and width 12.70 mm. The Mz designation indicates the specific lip and metal body configuration. Always compare these three measurements against your actual shaft and housing before installation; even a few tenths of a millimeter can affect fit and sealing performance.
Seals of this size appear in gearboxes, speed reducers, centrifugal pumps, electric motors, fan shafts, and power transmission components. In each case, the seal retains oil or grease inside the assembly while blocking dust, water, and particles from entering. It also serves as a secondary barrier in housings and hubs where bearings need extra protection from the environment.
Selection involves more than dimensions. Consider shaft speed, operating temperature, and the lubricant being used. The lip must run on a smooth, ground shaft surface without grooves. If the shaft shows wear marks, an offset lip seal or a wear sleeve may be a better choice. During installation, apply lubricant to the lip, avoid impacts, and ensure the seal sits centered so it does not run at an angle.
If you need an alternative within the DBH line, we can help. Provide the shaft diameter, housing diameter, and height you measured, along with a photo or the code from the old seal. With that information, we review options from the same family and confirm which one matches your equipment.

Frequently asked questions
- What are the dimensions of the DBH 5949 oil seal?
- It fits a 29.59 mm shaft, a 56.57 mm housing, and has a 12.70 mm height, with Mz design. Verify these against your actual shaft and housing before installing.
- How do I request an equivalent if I cannot find code 5949?
- Send the old code and the shaft, housing, and height dimensions via WhatsApp. We will review the DBH line and compatible families to offer a suitable alternative.
- What should I check before installing a radial shaft seal?
- Ensure the shaft has no grooves or burrs, lubricate the lip, and verify it is centered in the housing. A tilted installation or damaged lip will reduce seal life.
