The DBH 5255 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 22.22 mm shaft, 34.92 mm housing and 7.93 mm height correspond to an Lx design, with an elastomer lip and metal reinforcement. It is used in gearboxes, pumps, electric motors and transmission equipment that operate with shafts of that diameter.
The DBH 5255 is a radial-type oil seal with the designation 5255. Its published attributes are: shaft diameter 22.22 mm, housing diameter 34.92 mm and height 7.93 mm. The Lx design indicates a single-lip configuration with a spring, intended for rotating shafts with lubrication. The elastomer of the lip seals against the shaft surface and the steel outer ring ensures the fit in the housing. It is a standard replacement part within the seals and oil seals category.
Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases it serves to confine the oil or grease inside the assembly and prevent the entry of external contaminants. It is also used in machine tools, process equipment and hydraulic systems where the shaft rotates at moderate speeds and the operating temperature is compatible with the lip material.
To select the oil seal correctly, verify that the shaft, housing and height dimensions match those of the assembly. The shaft surface must be ground and free of splines or burrs; the housing must be clean and free of deformation. During installation, lubricate the lip with the same oil used in the equipment and use an installation tool so as not to damage it. If the shaft shows wear, consider a nearby size or a seal with the lip in another position.
