Part of the DBH line, the 9402 is a radial shaft seal that sits between a turning shaft and a stationary housing. It keeps lubricant where it belongs and keeps dust, water and other particles out. The Lx design means a metal case with one sealing lip, sized for a 33 mm shaft and a 50 mm housing. Gearboxes, pumps, motors and similar transmission equipment rely on seals like this to shield bearings and gears.

The code breaks down simply: 9402 identifies the item within the DBH family, and Lx describes the construction. Measurements are shaft 33 mm, housing 50 mm, height 10 mm. Because the numbering is consistent across the line, comparing the 9402 against neighboring sizes takes only a moment.

Where does a seal this size turn up? Reducers, centrifugal pumps, electric motors, compressors and general power transmission assemblies are common hosts. Machine tools, food processing equipment and process lines also use it, anywhere oil or grease has to stay inside and bearings have to stay protected from the surroundings. In every case the seal runs against a rotating shaft inside a fixed bore.

Installation rewards a little care. Confirm the shaft measures to spec and carries no burrs or scratches, and that the bore is clean and undistorted. Put a film of lubricant on the lip, then seat the seal square to the shaft, pressing on the outer edge rather than striking the lip. Where contamination or temperature runs high, a second lip or another compound may be worth discussing. Speed, pressure and the lubricant in use all feed into the choice.

Looking for a substitute? Pass along the code 9402 along with shaft, housing and height figures. A photo of the worn seal or the housing drawing speeds things up. From there we check options in the DBH line and among the other brands we carry, and we confirm which one fits your equipment.
