The DBH 8426 is a radial shaft seal built around a single sealing lip and a metal case. It sits on a 56 mm shaft and presses into a 73 mm housing bore, keeping lubricant in and contaminants out. Its stepped height, from 8 to 12.50 mm, suits housings of different depths, including those where the original seal was a different height.

The dimensions are shaft 56 mm, housing 73 mm, height 8.00/12.50 mm. The A 103 designation refers to the single-lip, metal-cased construction used for moderate-rotation duty. Because the height is not a single fixed value, the seal can be seated at the position that matches the housing depth without remachining the bore.

You will find this seal on centrifugal pumps, electric motors, gearboxes, conveyor rollers and other power transmission equipment. In each case it closes the gap where lubricant would otherwise escape and where dust, water or particles would otherwise enter. That protection matters for the bearings and bushings nearby, which is why the seal is a common item on preventive maintenance schedules.

Before pressing the DBH 8426 into place, confirm the shaft measures 56 mm and the housing 73 mm, and check both surfaces for burrs or scratches that could cut the lip. Coat the lip with the same oil or grease the equipment uses, then drive the seal in by the metal case, not by the lip. The 8.00/12.50 mm height gives you room to set the installation depth. If the shaft is worn, a repair sleeve is an option to consider.

If you need the same envelope with a different height or lip style, quote part number 8426 and the team can search for a variant. Alternatives from other brands are also possible as long as the shaft and housing dimensions are respected. Send the original seal's measurements or the number stamped on it and we will match it.
