The DBH 8116 is a radial shaft seal with an Lz design, sized for a 33 mm shaft, a 50 mm housing bore, and a 6 mm width. It keeps lubricant in and contaminants out on rotating shafts where axial space is tight. Common in pumps, motors, gearboxes, and similar transmission equipment, it is a wear part that protects bearings and gears.

This lip seal, part number 8116, comes from the DBH brand. The Lz designation indicates a single lip with a spring, suited to rotating shafts under permanent lubrication. The elastomeric lip rides against the shaft while the metal outer case holds a firm interference fit in the housing. As a wear item, it shields bearings, bushings, and gears from dust, water, and particles.

You will find it on electric motors, centrifugal pumps, speed reducers, compressors, mixers, and power transmission equipment. It also appears on fan shafts, conveyors, and machine tools where radial and axial room is limited. In every case it does two jobs: retaining oil or grease inside the assembly and blocking outside contamination. Maintenance teams use it in both preventive and corrective work.

Selection depends on shaft speed, operating temperature, and the lubricant in use. Confirm the shaft diameter falls within the recommended tolerance and that the housing bore is free of burrs or wear. Lubricate the lip with the same oil or grease as the equipment before pressing the seal in perpendicular to the shaft. Use a tube or installation tool of the correct diameter and avoid striking the lip. If the shaft shows a groove or marked wear, repair it or consider a seal with an offset lip.

For an equivalent, send the part number 8116 together with the shaft, housing, and width dimensions. A photo of the old seal or the assembly drawing also helps. With that information we check alternatives in the same radial shaft seal category and confirm compatible options. If the Lz design does not fit your application, other lip configurations and materials are available based on the fluid and working temperature.
