A radial shaft seal from DBH, part number 9797, sized for a 33 mm shaft, a 45 mm housing bore and a 10.50 mm overall height. Its Lx configuration pairs a sealing lip with a dust lip, so rotating assemblies keep their lubricant in while grit and external dirt stay out. That extra barrier is what protects bearings and bushings from premature wear in dirty surroundings.

Reading the code helps when you are matching a replacement: 9797 is the DBH reference, and the three figures that matter at the bench are shaft 33 mm, housing 45 mm, width 10.50 mm. The Lx designation tells you there are two lips. The inner one rides on the shaft and does the sealing; the outer one faces the environment and blocks particles. Both only work as intended when the seal sits square in the bore.

You will find this size in gearboxes, pumps, electric motors, reducers and other power transmission assemblies, wherever a turning shaft has to be separated from the outside. Industrial machinery, process equipment and vehicles that see dust or moisture are the usual homes for an Lx seal, since a single lip alone would not hold up as well there.

Before fitting, confirm the shaft measures 33 mm and the bore 45 mm, check for burrs and make sure the 10.50 mm height fits the housing depth. Coat the lip with lubricant, then drive the seal in with a tool that bears on the outer diameter only. Never push on the lip. On a worn shaft, plan on positioning the lip on a fresh track.

If you are replacing a seal and want an alternative, send part number 9797 or simply the three dimensions by WhatsApp or email. The team can search the DBH line and other brands we supply, keeping the dimensions and design type intact, and will tell you if the original used a different lip style or if the housing will take a variant.
