The DBH 8921 is a radial lip seal that sits in the housing and rides against a turning shaft, holding lubricant in and keeping dust, water and particles out. With a 48 mm shaft, a 70 mm housing bore and a 10 mm height, plus its Lx design, it fits gearboxes, pumps, electric motors and transmission equipment where sealing has to be dependable and replacement straightforward.

Reading the code is simple: 8921 identifies the seal, while the three figures describe the fit. Shaft 48 mm, housing 70 mm, width 10 mm. The Lx designation covers a lip-type seal built to a particular configuration within the series. Inside, a flexible lip presses on the shaft and a small spring keeps that contact steady, so oil or grease stays where it belongs and outside contamination stays out.

You will find this seal wherever a shaft turns inside a lubricated housing. Gearboxes, centrifugal pumps, electric motors, rollers, belt and chain drives, mixers, fans and machine tools are all typical. The job is the same in each case: keep the lubricated side separate from the surrounding environment and protect bearings and gears from premature wear.

Before fitting, confirm the shaft measures 48 mm and the bore 70 mm, and that the 10 mm width clears the cavity. The shaft surface should be clean, free of burrs and scoring, and the housing should not be distorted. Coat the lip with lubricant before pressing the seal in and keep the installation square, without hammer blows. Where the shaft is already worn, a seal with a second lip is worth considering.

If you are after an equivalent or another size, give us the code 8921 or the measurements of the seal you are replacing. From there we can look at options within the same series or in other brands we supply. We can also help when shaft or housing tolerances are unusual, so the lip design and material suit the application.
