The DBH 8928 is a radial shaft seal designed for rotating shafts, featuring a sealing lip with spring and an outer case that presses into a cylindrical bore. Its reference number 8928 corresponds to a 50 mm shaft, 72 mm bore, and 7 mm width. This seal keeps lubricant in and contaminants out in gearboxes, pumps, motors, and transmissions.

As a lip seal, the DBH 8928 combines a flexible sealing lip that rides on the shaft with a metal case that fits by interference in the housing. The lip design includes a spring that maintains contact, making it suitable for lubricated rotating applications. The static seal occurs between the case and the bore, while the dynamic seal forms at the lip-to-shaft interface.

Common installations include gear reducers, centrifugal pumps, electric motors, compressors, and power transmission assemblies. In these setups, the seal prevents oil or grease from escaping and stops dust, water, or particles from reaching bearings and internal components. It is also found in agricultural equipment, process machinery, and hydraulic systems where lubricant containment at input or output shafts is necessary.

Proper selection starts by checking the shaft diameter and bore diameter against the stated dimensions. The shaft surface should be ground and free from deep scratches or wear that could harm the lip. The bore must have the correct diameter and finish for a secure fit. During installation, coat the lip with the same lubricant used in the equipment and use a proper driver to avoid deforming the seal or dislodging the spring. Never strike the lip directly.

If you need a replacement or an equivalent, provide the code 8928 or the dimensions 50x72x7 mm. MR Industrial Accessories can review options within the same seal and oil seal category and help you choose the right one for your equipment. We can also assist if your shaft or bore has special tolerances.
