Part number 5683 is a DBH radial shaft seal, a lip-type wear part that presses into the housing and rides on the rotating shaft. It holds lubricant inside the assembly and keeps dust, water and particles out. The size falls in the medium range: shaft 34.92 mm, housing 53.49 mm, width 15.87 mm. Because the lip is a running surface, hardening or scoring on it is the usual sign that replacement is due.

The 5683 belongs to the Lx configuration, meaning one lip with a spring. The elastomer body does the sealing, while the garter spring keeps steady pressure against the shaft and absorbs minor misalignment. Shaft, housing and height figures should always be confirmed against the old seal or the equipment drawing before a quote is issued.

Seals in this size range show up in gear reducers, centrifugal pumps, motors, line shafts and process machinery, as well as conveyors, farm implements and hydraulic circuits. The job is the same everywhere: stop oil from escaping and keep contaminants away from bearings and gears.

Installation decides how long the seal lasts. Inspect the shaft for burrs, deep scratches or a visible wear track, and make sure the bore is clean and undistorted. Coat the lip with lubricant, then drive the seal in with a tube that contacts only the outer diameter. Never strike the lip. Where the shaft is grooved, seating the seal slightly deeper lets the lip run on fresh metal.

To quote 5683, send the part number together with the three dimensions. From that we can review alternatives in other brands or lip styles within the same family. A photo of the removed seal and of its mounting position also helps us confirm the design before quoting. MR Industrial Accessories LLC supplies the DBH line as part of its seal and oil seal range.
