The DBH 8038Vit is a radial shaft lip seal sized for a 42 mm shaft, a 56 mm housing bore and a 7.00 mm height. Its Lx-R configuration pairs a primary sealing lip with a secondary dust lip, so lubricant stays in while dirt is kept out. Gearboxes, pumps, electric motors and power transmission assemblies are common homes for this seal.

Reading the size off this seal is straightforward: shaft 42 mm, housing 56 mm, width 7.00 mm. The Lx-R label tells you there are two lips working together. The main lip rides the rotating shaft and holds oil or grease in place; the extra lip sits outboard and blocks dust and particles. Meanwhile, the outer diameter presses into the bore to create the static seal.

Where does it fit? Gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment all use seals of this type. The job is always the same: keep the lubricant where it belongs and keep contaminants away from bearings and sliding surfaces. Treat it as a wear item and swap it out once leaking or unusual noise shows up.

Installation notes: the shaft and bore should be clean, with no burrs or scratches. Coat the lip with the same oil or grease the equipment runs on, then drive the seal in with a tube that contacts only the outer diameter, never the lip. The 7.00 mm height typically sits flush or slightly recessed, depending on the cover. If the shaft itself is worn, a seal with the lip positioned elsewhere may be the better choice.

Looking for a replacement? Send the code stamped on the old seal along with the shaft, housing and height measurements, plus a photo. That is enough for us to search the DBH line or other brands we supply. We can also tell you whether the Lx-R design suits your case or whether a different lip style would serve you better.
