The DBH 5813 is a radial shaft lip seal used to keep lubricant inside a housing and keep dust, water and other contaminants out. It fits a shaft measuring 52 mm, a housing bore of 80 mm and a width of 7.00 mm, so it suits assemblies where axial room is limited. The seal is pressed into the housing bore while its flexible lip rides against the rotating shaft, absorbing small amounts of misalignment as the equipment runs.
Reading the 5813 code gives you the size: shaft 52 mm, housing bore 80 mm, width 7.00 mm. The A 012 designation describes a single lip with a spring, the common arrangement for rotating shafts. The elastomer lip wipes against the shaft surface, and the outer diameter grips the housing bore to close off the leakage path. When a machine calls for this exact size, the seal drops in as a direct replacement.
Typical locations include gearboxes, pumps, electric motors, mixers and conveyors, wherever oil or grease has to stay in and dust or water has to stay out. The same seal turns up in power transmission assemblies and in agricultural and process machinery. Its job is to protect the bearings and gears behind it and to cut down on corrective maintenance caused by leaks.
Installation starts with the shaft. It should be clean, free of burrs and scratches, and the sealing surface needs the right hardness and surface finish. Coat the lip with lubricant before pressing the seal in, keep it square to the shaft and avoid hitting the elastomer. A worn shaft may call for a repair sleeve or a different size. Speed, temperature and the fluid being sealed all affect which seal you choose.
For an equivalent, send code 5813 or the shaft and housing dimensions. We can search other brands and configurations within the same seal category. It also pays to inspect the shaft and housing before fitting a new seal, since a damaged counterface will not seal reliably.

Frequently asked questions
- What size is the DBH 5813 oil seal?
- Shaft 52 mm, housing bore 80 mm, width 7.00 mm. It is a radial shaft seal of design A 012, single lip with spring. Those three figures are what the 5813 code stands for.
- How can I tell whether this seal replaces the one in my machine?
- Measure the shaft diameter, the housing bore and the housing width. A match at 52, 80 and 7 mm means the 5813 fits. Check the lip type and material too, particularly for high temperatures or aggressive fluids.
- What should I watch for when fitting a radial shaft seal?
- Clean the shaft and housing, remove burrs, and lubricate the lip before pressing it in. Keep the seal square and apply even pressure without striking the elastomer. The spring goes on the fluid side, and the shaft should not be badly worn.
