The DBH 5798 is a radial shaft seal designed to keep lubricant in and contaminants out of rotating equipment. Its three key dimensions are shaft 42.86 mm, housing 69.88 mm, and width 12.70 mm, matching the Mz design with a sealing lip and metal case. You will find it in gearboxes, pumps, motors, and transmissions where a shaft turns inside a stationary housing. MR Industrial Accessories supplies this brand and helps you select the right seal.
This seal carries the numeric code 5798. The Mz design refers to a lip seal with a metal reinforcement, built to retain oil or grease on a rotating shaft. The dimensions—shaft 42.86 mm, housing 69.88 mm, width 12.70 mm—let you replace a worn seal without machining the housing or shaft, provided the original tolerances are still within spec.
Common installations include gearboxes, centrifugal pumps, electric motors, rollers, and belt or chain drives. In each case, the seal acts as a barrier between the lubricant and the outside environment, shielding bearings and bushings from dust, water, and particles. In continuous-process equipment, even a minor leak can lead to unplanned downtime, so this seal is often found in medium-sized industrial machinery.
Proper installation starts with clean, burr-free shaft and housing surfaces. Lubricate 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 shim—never strike the lip directly. If the shaft shows wear, a repair sleeve may be needed. Selection also depends on speed, temperature, and lubricant type.
To find an equivalent, send the code 5798 along with the shaft, housing, and width dimensions from your equipment. A photo of the old seal or the drawing also helps. At MR Industrial Accessories, we compare that data against available options and confirm the best match for your application.

Frequently asked questions
- What are the dimensions of the DBH 5798 seal?
- The DBH 5798 seal has a shaft diameter of 42.86 mm, a housing diameter of 69.88 mm, and a width of 12.70 mm. These dimensions correspond to the Mz design and must match your equipment's housing and shaft for proper sealing.
- How can I tell if this seal will replace the one I have?
- Check the three diameters: shaft, housing, and width. If they match your old seal and the design is compatible, it should work. If unsure, send us a photo or the code on WhatsApp and we will verify it against the manufacturer's data sheet.
- What does the Mz design mean in a radial shaft seal?
- The Mz design indicates a specific construction with a sealing lip and reinforcement body. It does not change the dimensions, but it defines the application type and mounting direction. Always confirm against the technical data sheet before installing.
