The DBH 8626Pol is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its code tells you the three critical dimensions: 70 mm shaft, 87 mm housing bore and 8.50 mm height. The Lx-R-AH design combines a sealing lip with a reinforced outer body, so it presses into a cylindrical housing while the internal spring maintains lip contact on the shaft. You will find this seal in gearboxes, pumps, motors and other power transmission assemblies where oil or grease must stay put.

When reading the 8626Pol code, start with the shaft size. The 70 mm figure is the diameter the lip rides on, the 87 mm figure is the bore it presses into, and 8.50 mm is the overall width. These are the three measurements to confirm before ordering, because a seal that is off on any one of them will not seat or seal correctly. The Lx-R-AH designation points to a lip seal with a reinforced case, a common configuration for cylindrical housings in industrial drives.

In service, the elastomer lip and the internal spring work as a pair. The spring keeps the lip in light contact with the rotating shaft, while the elastomer accommodates minor misalignment and surface finish variation. This arrangement retains oil or grease inside the housing and blocks dust, water and particles from entering. Typical installations include gear reducers, centrifugal pumps, electric motors, rollers and transmission equipment running at moderate temperatures within the seal material's limits.

Installation is straightforward if you prepare the surfaces. Wipe the housing bore and shaft clean, check for burrs, nicks or wear on the shaft, and apply a thin film of lubricant to the lip before sliding the seal into place. Press it in squarely, using a flat driver or sleeve that contacts the outer edge, not the lip. Impact blows or a cocked seal will deform the lip and cause early leakage. If the application involves heavy vibration or elevated temperature, ask about an alternative compound or design before you install.

If you need a replacement or an equivalent, send the code 8626Pol or the shaft, housing and height dimensions. A photo of the old seal or the housing drawing also helps. The team compares your data against the DBH line and confirms which option fits without modifying the mounting. For a quote, message WhatsApp with the part number and quantity, or email the same details. You can also ask about other seals, bearings or power transmission supplies at the same time.
