A radial shaft seal such as the DBH 9951/85 keeps lubricant where it belongs and keeps contaminants out. It sits between a rotating shaft and its housing, which makes it a common sight in gearboxes, pumps, motors and power transmission assemblies. The A 100 design and its compact footprint suit tight installation spaces.
Reading the code starts with the three measurements. This seal fits a shaft of 18.80 mm, a housing bore of 29.30 mm and a width of 7.00 mm. The A 100 design is a single-lip seal with a metal case and a sealing lip, built for lubricated rotating shafts. Within the DBH line, 9951/85 pins down one specific size, so it pays to confirm those three values before you commit to an order. The shaft figure drives the fit; the width tells you how much room the housing has.
You will find this type of seal in reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In each case it works on a turning shaft and forms the barrier between the oil or grease inside and the surrounding environment. Machine tools, washing equipment and any setup exposed to splash or dust are other places it turns up. Where vibration or temperature runs high, check the lip material before you fit a replacement.
Installation rewards preparation. The shaft should be clean and free of burrs and marks, and the housing should be free of deformation. Coating the lip with the same oil or grease the equipment uses helps it seat without damage, and an installation tube should press on the metal edge rather than the lip. Shaft speed, operating temperature and the fluid being retained all shape the selection. If the seal you are removing has a spring or an auxiliary lip, keep that configuration in the replacement.
For a quote on code 9951/85, send the shaft, housing and width dimensions together with a photo of the old seal. We can search the DBH line or other brands we supply for a match, working within your housing tolerances. Details such as lip material, fluid type and temperature make the proposal more precise.

Frequently asked questions
- What are the dimensions of the DBH 9951/85 oil seal?
- Shaft 18.80 mm, housing 29.30 mm, width 7.00 mm, in design A 100. Check all three values before ordering, since a mismatch on the shaft or housing will prevent a correct fit.
- How do I confirm this seal replaces the one in my equipment?
- Measure the shaft, housing bore and width of the original seal and compare them with the 9951/85. When all three agree, it fits. Also review the lip type and material if the equipment runs hot or handles aggressive fluids.
- Can I get a size other than 9951/85?
- Yes. Send the dimensions you need on WhatsApp, or a photo of the original seal, and we will look for a match in the DBH line or in other brands we supply.
