The DBH 8343 radial shaft seal is a lip seal that fits on the shaft and seals against the housing to keep lubricant in and contaminants out. Its dimensions are 63 mm shaft diameter, 90 mm housing diameter and 7.70 mm height, a size that appears in gearboxes, pumps and power transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the size for your application.
This seal carries the designation 8343 and the A 099 design. It is a single-lip seal for rotating shafts: the flexible lip runs on the shaft to create the seal, while the outer body stays fixed in the housing. It works with oil or grease and is not a substitute for a mechanical seal in pressurized fluid applications.
Seals of this size are common in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. Their job is always the same: retain oil and block dust, water or particles that would otherwise speed up wear on bearings and gears. They also serve as a secondary barrier in dusty or wet environments, as long as the shaft and housing are in good condition.
During installation, confirm that the shaft is free of burrs, scratches or wear on the lip track and that the housing is clean and undistorted. Apply lubricant to the lip before fitting, and press the seal in perpendicular to the shaft using a tube or press that contacts the outer edge, never the lip. If the shaft has a deep groove, consider a seal with the lip positioned on a different track.
Need an equivalent or another size? Send the code 8343 together with the shaft, housing and height dimensions, and a photo or sample of the old seal. With that information we can review options within the DBH line and other brands we carry. If the housing or shaft is worn, we can also look at repair or adaptation alternatives before settling on a replacement.

Frequently asked questions
- What are the dimensions of the DBH 8343 seal?
- It has a 63 mm shaft diameter, 90 mm housing diameter and 7.70 mm height, with an A 099 design. These are the dimensions shown on the product page. If your shaft or housing measures differently, send us the values and we will look for the equivalent option.
- How do I know if this seal replaces the one I have installed?
- Check the shaft diameter, housing diameter and height. If they match 63, 90 and 7.70 mm, it is compatible. Also verify that the lip type and material suit the temperature and lubricant in your equipment. If unsure, ask us with a photo.
- Can I request an equivalent if the shaft is worn?
- Yes. If the shaft shows wear, we can evaluate a seal with the lip in a different position or an alternative size that fits the housing. Send the code 8343, the current dimensions and a photo of the sealing area on WhatsApp so we can review it.
