The DBH 9886 is a radial shaft lip seal built to hold lubricant in and keep contaminants out of rotating shaft assemblies. Its metric size is 25 mm at the shaft, 34.20 mm at the housing bore and 12.0/16 mm in height, and its design reference is A 334. MR Industrial Accessories LLC supplies this seal and can help you match it to your equipment.

Reading the code is straightforward: the 9886 designation in the DBH catalog points to a specific metric size, and the values behind it are shaft 25 mm, housing 34.20 mm, height 12.0/16 mm. The height is given as a range because the seal can sit at different depths depending on how the housing is machined. Design A 334 describes the lip profile and outer body geometry. The seal combines an elastomer sealing element with a metal case.

On the equipment itself, the seal sits where a shaft passes through a housing and lubricant has to stay on one side. Gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and other transmission equipment are common locations, and the same applies to conveyors, agricultural machinery and hydraulic systems with lubricated rotating shafts. In each case it works together with the bearing or bushing at that point, keeping oil or grease where it belongs and blocking dust and water from reaching internal parts.

Because the lip runs against the shaft, the seal is a wear item and is normally changed as part of preventive maintenance. Before fitting a replacement, confirm the shaft measures 25 mm and the housing bore 34.20 mm, and check that the shaft surface is smooth and free of burrs. The 12.0/16 mm height gives you some latitude on installed depth, so follow the depth called for by the housing design. Coat the lip with lubricant before pressing it in and use a proper installation tool to avoid damaging the sealing edge. If the shaft shows wear at the lip contact area, a repair sleeve or a different size may be the better route.
