The DBH 8922 is a radial shaft lip seal sized for a 50 mm shaft, a 70 mm housing bore and an 8 mm height. It sits between a turning shaft and a stationary housing, keeping lubricant in and keeping dust, water and other particles out. These proportions suit mid-size transmission components such as gearboxes, pumps and electric motors. MR Industrial Accessories supplies the DBH brand as part of its seals and oil seals range.

The 8922 code covers this particular size in the DBH line. The seal uses the Lx design: a sealing lip combined with a metal case, built for rotating shafts that run with lubrication. The three figures to confirm before ordering are shaft 50 mm, housing 70 mm and height 8.00 mm. If any of them differs on your equipment, a different reference is required.

You will find seals of this size in gearboxes, speed reducers, centrifugal pumps, electric motors and other power transmission assemblies. In each case the job is the same: hold oil or grease inside the assembly and keep outside contamination from reaching the bearing. Because the lip runs against the shaft, the part wears. With time the lip stiffens or loses material, and lubricant starts to escape.

Selection involves more than the three dimensions. Shaft speed, operating temperature and the lubricant in use all influence how long the seal performs and which compound suits the job. The Lx design fits rotating shaft positions lubricated with oil or grease. At installation, coat the lip with lubricant, inspect the shaft for burrs or score marks, and press the seal in squarely rather than hammering on the face. A worn housing seat may call for repair before the new seal goes in.
