The DBH 9422 is a radial shaft seal made to sit in the housing and ride against a rotating shaft, holding lubricant in and keeping dust, water and particles out. It follows the Lx construction and measures 50 mm at the shaft, 80 mm at the housing and 8.00 mm in height. That size range suits medium-section shafts found in pumps, motors, gearboxes and industrial drives.

The code tells you most of what you need: the Lx designation points to a particular build within the DBH line, and the three figures cover shaft, housing and height — 50 mm, 80 mm and 8.00 mm. The outer case presses into the housing while the lip contacts the shaft. If you need specifics on the lip profile or the spring, the manufacturer's data sheet is the place to confirm them.

You will find this seal in centrifugal pumps, electric motors, gearboxes, transmission shafts and process equipment. It does two jobs at once: it stops oil or grease from escaping and blocks contaminants from getting in. Where dust, wash water or fine chips are present, choosing the right seal helps bearings and gears reach their expected service life. It also fits shafts turning at moderate speed in normal temperature conditions.

Before installing, make sure the shaft is clean and free of burrs or marks, and that the housing bore has no dents. Coat the lip with the same oil or grease the equipment uses, then press the seal in straight so the lip is not distorted — a tube or press that bears on the outer edge works well. If the shaft is worn, an offset-lip seal may be the better choice. Speed, temperature and the fluid being retained all factor into selection.

Need a different size or a cross-reference? Send the full seal part number, the shaft, housing and height dimensions, and a photo or sample if you have one. We can also check another brand or series with the same dimensions. MR Industrial Accessories supplies customers across the US and in several Latin American countries, and our team helps you pick a seal that does its job without oversizing.
