The DBH 9739 is a single-lip radial shaft seal with a spring, built to keep lubricant in and contaminants out of rotating equipment. It fits a 19 mm shaft, presses into a 25.40 mm housing bore, and measures 3.20 mm in height, so it works well where axial space is limited. This seal is a common replacement item in industrial and automotive assemblies.

Use the code 9739 to identify the seal. Its size is given as shaft 19 mm, housing bore 25.40 mm, and height 3.20 mm. The Mt design means a single lip with a spring, intended for lubricated rotating shafts. The small 3.20 mm height allows installation in shallow housings. DBH is one of the brands MR supplies, so you can order it under its exact designation.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, and transmission equipment. It also appears in agricultural machinery, conveyors, and hydraulic systems where a shaft turns inside a housing. Because of its compact size, it is common in small mechanisms such as rollers, pulleys, and fan shafts. In every case, the job is the same: hold the oil or grease in place and shield the bearings from dust, water, and particles.

Before fitting, confirm the shaft is 19 mm and free of burrs or scratches, and check the 25.40 mm bore the same way. Coat the lip with the same lubricant used in the machine, then press the seal in with a support tube that contacts only the outer diameter, never the lip. The 3.20 mm height should sit flush or slightly recessed. If the shaft is worn, look into a repair sleeve or a different size.

If you need a replacement for the DBH 9739, send the code 9739 along with your shaft, bore, and height measurements. With that information we can look for other brands or series that do the same job. We can also help if space is tight or if the Mt design is not right for your application.
