When a pump, motor or gearbox starts weeping oil around the shaft, the DBH 8392 radial shaft seal is one of the sizes worth checking first. It is a lip seal that keeps lubricant where it belongs and blocks dust, water and other contaminants from working their way in. The size is written as shaft 25.00 mm, housing 35.00 mm and height 5.00 mm, and the Lx design means a single sealing lip with a spring. MR Industrial Accessories supplies this brand and can help you confirm whether it fits your equipment.

The 8392 part number identifies a DBH radial shaft seal built for rotating shafts. Read the three figures in order: the shaft it rides on is 25.00 mm, the bore it presses into is 35.00 mm, and the overall height is 5.00 mm. The Lx configuration uses one sealing lip backed by a spring, which is the common choice for lubricated rotating service. Keeping the 8392 number on hand makes it simple to cross-check against other brands when a replacement is needed.

You will find this size in centrifugal pumps, electric motors, gearboxes, compressors and other power transmission equipment. In each case the seal sits in the cover or housing and runs against the shaft, holding oil in and keeping contamination out. Because the lip contacts a moving surface, it wears over time, so leaks, noise or a visible groove at the sealing area are the usual signs that replacement is due.

Matching the seal to the equipment starts with the shaft and housing measurements. The Lx design suits moderate speeds and low pressures, so confirm those conditions before installing. Lubricate the lip with the same oil the system uses, press the seal in square to the shaft, and take care not to nick the sealing edge. If the shaft itself shows wear, a version with an auxiliary lip may be the better route.
