Description
DBH 6800 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 6800 and any equivalents.
The DBH 6800 is a radial shaft seal that keeps oil, grease, or water from escaping along a rotating shaft. It also blocks dust, chips, and moisture from reaching bearings, bushings, and gears. The seal presses into the housing and its lip rides on the shaft, so the shaft surface must be ground and free of marks for proper sealing.
This oil seal follows the A 025 design: a single lip with a spring, an outer metal case, and an elastomer lip that makes radial contact on the shaft. Dimensions are shaft 47.62 mm, housing bore 73 mm, and height 12.20 mm. That size range fits many gearboxes, pumps, and power transmission units.
Typical uses include gearboxes, speed reducers, centrifugal pumps, mixers, chain conveyors, and process equipment with a shaft turning inside a lubricant-filled housing. Electric motors and machine tools also use this size when shaft and housing match the stated dimensions and the rotation speed suits the lip material.
When selecting or installing, check three points: shaft diameter within tolerance with suitable hardness and roughness; housing diameter and chamfer correct to avoid damaging the case during pressing; and rotation direction and lubricant type compatible with the lip compound. Lubricate the lip before assembly and use a tube or socket that contacts the metal edge, never the elastomer.
For an equivalent, send code 6800 with the shaft and housing dimensions, a photo of the old seal, and the original brand and code if available. We can then find an alternative from the same series or another brand that matches dimensions and service conditions, with no need to modify the shaft or housing.

Frequently asked questions
- What are the dimensions of the DBH 6800 oil seal?
- Shaft diameter 47.62 mm, housing bore 73 mm, height 12.20 mm. It is an A 025 design with a single lip and spring. Verify shaft and housing tolerances before installation.
- How do I request an equivalent size?
- Send code 6800, the shaft and housing dimensions, and a photo of the original oil seal via WhatsApp. We will look for a compatible alternative in dimensions and working conditions without modifying the shaft or housing.
- What should I keep in mind when installing it?
- Lubricate the lip before assembly, rest the installation tube on the metal edge and not on the elastomer, and check that the housing chamfer has no burrs. A scratched shaft or one with inadequate roughness shortens seal life.
