When a shaft turns inside a housing, lubricant has to stay in and dust has to stay out. The DBH 8129Pol radial shaft seal handles that job. Its three key measurements are shaft 44.20 mm, housing 60.00 mm and height 7.00 mm, and the designation to quote is 8129Pol.

The 8129Pol code identifies a lip seal built in the Lx-R configuration: a sealing lip combined with a reinforced body. That arrangement is what allows it to hold grease or oil on one side of the housing while blocking contaminants on the other. Because it sits on a rotating shaft, it belongs to the group of parts that maintenance teams replace on a regular schedule.

You will find this seal wherever a shaft passes through a machined bore: gearboxes, centrifugal pumps, electric motors, reducers, conveyor rollers, machine tools and other process equipment. In every case the lip rides against the running surface of the shaft and forms the dynamic seal inside the housing bore.

Installation is straightforward but not forgiving. Clean the shaft and the bore, remove burrs and scratches, and put a light film of lubricant on the lip before pressing the seal in. It should enter straight and seat fully against the bottom of the housing; striking it can distort the lip and cause a leak. When you pick a replacement, look beyond the three dimensions: the lubricant type, the operating temperature and the shaft speed all matter. A worn shaft may call for a repair sleeve.

For an equivalent, send the code 8129Pol or the measurements of the seal you are replacing, meaning shaft diameter, housing diameter and height. We compare those figures against the options we handle and come back with compatible choices. We can also confirm whether the Lx-R design fits your equipment or whether a different lip style would serve you better.

The DBH brand is part of our seals and oil seals line. If you want to verify a designation or check an application, message the team with the part number and we will answer with the technical details you need.
