The DBH 8647 is a single-lip radial shaft seal that keeps lubricant inside and contaminants outside. It fits a 46 mm shaft, a 59.10 mm housing bore and has a 12.00 mm height. The lip rides on the rotating shaft while the metal case presses into the housing. This size is common in gearboxes, pumps, electric motors and other power transmission equipment. MR Industrial Accessories supplies it as part of its seals and oil seals line.
The 8647 code identifies this specific size in the DBH line. The seal has an Lx design: a sealing lip and an outer metal case. Shaft diameter (d) is 46 mm, housing diameter (D) is 59.10 mm, and height (h) is 12.00 mm. The lip contacts the shaft, and the outer diameter seats in the housing with an interference fit. Use the code to order without confusion.
Seals of this size appear in equipment with rotating shafts: gearboxes, centrifugal pumps, electric motors, rollers and machine tools. They also close bearings and housings where grease must stay in and dust, water or particles must stay out. This is a wear part. When the lip hardens or the shaft shows marks, oil starts to escape. Replace it before the bearing is damaged.
Before installing, make sure the shaft is clean and free of burrs or deep grooves. The sealing surface needs the correct hardness and finish. Lubricate the lip, then insert the seal perpendicular to the shaft. Use a tube or press that pushes on the outer diameter, never on the lip. If the housing has burrs or the bore is out of round, the seal will leak even if the size is right. In that case, inspect the housing before fitting the replacement.
To request a quote for code 8647, send the dimensions of your old seal: shaft diameter, housing diameter and height. With those three values we find the equivalent in DBH or another brand in the same category. We can also help if the original seal has a special feature, such as a double lip or dust guard, so the replacement does the same job.
MR Industrial Accessories supplies the DBH brand within its seals and oil seals range. For a quote on the DBH 8647, message us on WhatsApp with code 8647 and we will reply with the alternative that best fits your equipment.

Frequently asked questions
- What are the dimensions of the DBH 8647 oil seal?
- Shaft diameter 46 mm, housing diameter 59.10 mm, height 12.00 mm. These three values identify the seal. If your old part has different dimensions, send them to us and we will look for the equivalent.
- How do I know if this oil seal replaces the one I have installed?
- Check the three dimensions: shaft, housing and height. If they match, the seal is compatible. Also confirm the lip type and material, especially for synthetic oils or high temperatures. If unsure, ask us with the code or a photo of the part.
- What should I keep in mind when installing a radial shaft seal?
- The shaft must be clean, free of burrs and with the right finish for the lip. Lubricate the seal before installing it and apply pressure on the outer diameter, never on the lip. Make sure it goes in perpendicular to the housing to avoid premature leaks.
