The DBH 9342 is a radial shaft seal built for rotary equipment, sealing against a 52 mm shaft inside a 70 mm housing bore with an 8.00 mm overall height. Its Lx construction defines the lip geometry and outer case used in this DBH series. Maintenance teams rely on seals like this one to hold oil or grease in place and to keep dust, water and other contaminants out of gearboxes, pumps, motors and transmission assemblies. MR Industrial Accessories LLC supplies this brand and can help match the correct seal to your application.

Reading the 9342 code tells you most of what you need before ordering. The seal fits a shaft measuring 52 mm, presses into a housing bore of 70 mm, and sits 8.00 mm tall in the cavity. The Lx designation identifies the lip and case configuration within the DBH line, so an interchange should match both the three dimensions and that design.

Functionally, the seal works through a flexible lip that rides directly on the machined shaft surface while the outer case holds firm in the bore. That contact keeps lubricant where it belongs and blocks abrasive particles, moisture and vapors that would otherwise shorten bearing and gear life. You will find seals of these proportions in speed reducers, centrifugal pumps, electric motors, compressors and belt or chain drive units, as well as in machine tools, industrial washers and conveyors operating in dirty or wet conditions.

Installation calls for a few checks. Confirm the shaft measures 52 mm and the bore 70 mm, and that the 8.00 mm height clears the cavity without being forced. Coat the lip with the same oil or grease the equipment runs on, inspect the shaft for burrs or scoring, and make sure the bore is clean and free of dents. Drive the seal in with a proper installation tube, keeping pressure even on the outer ring and away from the lip. A worn shaft surface may call for a seal with an auxiliary lip.

If you are sourcing an equivalent, send the complete part number, the brand and the three dimensions. From there we can check alternatives among the brands we supply or point you to a standard size that fits. Details such as a chamfered bore or a shouldered shaft are also useful. The more complete the information, the more precise our answer.
