The DBH 8621Pol is a radial shaft seal with a 70 mm shaft diameter, 88 mm housing bore, and 8.00 mm height. It keeps lubricant in and contaminants out of rotating shaft assemblies such as gearboxes, pumps, and motors. MR supplies this brand and can help you confirm the right seal for your equipment.

This lip seal carries the designation 8621Pol and the design Lx-H-H, which describes how the lip and outer case are arranged. It combines elastomeric sealing elements with metal reinforcement, following the manufacturer's series. The sealing lip rides against the rotating shaft while the outer surface stays fixed in the housing bore.

You will find seals in these dimensions on gearboxes, centrifugal pumps, electric motors, speed reducers, and other power transmission components. Their job is to hold oil or grease where it belongs and to block dust, moisture, and particles from reaching bearings and gears. Agricultural machinery, process equipment, and hydraulic systems also rely on this type of sealing when shafts turn at moderate speeds.

Proper installation starts with clean, burr-free shaft and housing surfaces. Apply a little of the service oil or grease to the lip, then press the seal in squarely with a suitable tube, avoiding any impact on the lip. When selecting a seal, account for shaft peripheral speed, operating temperature, and how the elastomer reacts to the fluid in use. A worn shaft may call for a seal with an auxiliary lip.

If you are looking for a replacement, send us the code 8621Pol or the shaft, bore, and height measurements of your current seal.
