The DBH 5679 is a radial shaft seal built to keep lubricant inside gearboxes, pumps and reducer housings while blocking dust and water from reaching the bearing cavity. Its Mz configuration pairs a primary sealing lip with a secondary protective lip, and the unit seats into the housing by press fit. Shaft 30.10 mm, housing 52.28 mm, height 11.50 mm, which makes it a practical replacement where axial room is tight.
The code 5679 belongs to the DBH line of radial shaft seals. Read the three figures in order: the shaft runs at 30.10 mm, the bore it presses into measures 52.28 mm, and the overall height is 11.50 mm. In the Mz design, one lip does the sealing against the rotating shaft and a second lip sits outboard to hold back contaminants. The elastomer lip contacts the shaft directly, while the metal case carries the interference fit in the housing.
Gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment are the usual homes for a seal this size. In every case the seal sits in the cover or housing and works against the shaft as it turns. Treat it as a wear item: once oil starts weeping or debris collects around the lip, replace it before bearings and gears take the damage.
Matching the seal to the machine means confirming all three values against the actual shaft and bore: 30.10 mm, 52.28 mm and 11.50 mm. The Mz design fits situations with moderate dust or water exposure. During installation, coat the lip with the same oil or grease the equipment runs on, seat the seal square to the shaft, and drive it in on the outer race only, keeping tools away from the lip. A worn shaft surface may call for a repair sleeve.
If the exact size is hard to source, send code 5679 or the measurements of the seal you are replacing through WhatsApp or email. We can search the DBH line or another brand we carry for a match, and we can tell you whether the Mz design suits the contaminant and shaft speed in your application. Our team replies promptly and helps with selection.

Frequently asked questions
- What size is the DBH 5679 oil seal?
- It fits a 30.10 mm shaft in a 52.28 mm housing bore, with a 11.50 mm height. Confirm those three values against your equipment before ordering. If any of them differs, ask us about an equivalent.
- What does the Mz design indicate?
- Mz means the seal has a main sealing lip plus a secondary lip that guards against dust and water. It suits moderate contamination. For heavily dirty conditions, look at a seal with an extra dust lip.
- How do I request the DBH 5679 or a substitute?
- Send code 5679 or the dimensions of your current seal on WhatsApp or by email. We will quote that size or an equivalent from the DBH line or another brand we supply.
