The DBH 6846 is a radial shaft seal built to keep lubricant where it belongs and to block outside contamination on rotating-shaft equipment. Its size — shaft 75 mm, housing 100 mm, height 19.50 mm — fits gearboxes, pumps and motors where there is not much room along the shaft. MR Industrial Accessories supplies this brand and helps you match the seal to the application.

The code DBH 6846 identifies the part; the three figures that matter when you read it are the bore it runs on (75 mm), the housing it presses into (100 mm) and its overall width (19.50 mm). The Lz designation describes a single lip with a spring, a configuration used to hold oil or grease in place while the shaft turns continuously. The elastomer lip rides on the shaft, and the metal outer case is press-fitted into the housing, so the seal works both as a static joint against the bore and as a dynamic seal against the rotating surface.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, line shafts and process machinery. Whatever the equipment, the job is the same: retain the lubricant inside the assembly and keep dust, water and particles away from the bearings. Treat it as a wear item — once it starts weeping, or the shaft feels stiff or noisy, it is time to pull it.

Before fitting, check that the shaft is within tolerance and free of burrs, scoring or deep marks. Put a light film of lubricant on the lip, then drive the seal in with a flat tool that bears on the case only, never on the lip. The 19.50 mm width has to line up with the housing depth so the seal ends up flush or slightly recessed, as the equipment design calls for.

When you need a replacement, send the full seal code, a photo of the part and caliper readings. With that we can search equivalents in this brand or in other brands we supply, keeping the shaft, housing and height dimensions intact. We can also tell you whether the Lz lip is the right choice for your service conditions.
