The DBH 5423 is a radial shaft seal designed to keep lubricant in and contaminants out of rotating equipment. With a 30 mm shaft, 47 mm housing, and 5.00 mm height, it fits small to medium transmission and rotating assemblies. As a wear part, it should be replaced once the lip hardens or shows damage, which leads to leaks.
This oil seal belongs to the DBH line and carries the code 5423. Its dimensions are shaft 30 mm, housing 47 mm, and height 5.00 mm. The Lx design indicates a single lip with a metal case and elastomeric sealing lip. It works by sitting in the housing cavity while its lip presses lightly against the rotating shaft.
You will find it in gearboxes, pumps, electric motors, fan shafts, rollers, and other power transmission equipment. Anywhere a shaft turns inside a housing with lubricant, this seal retains oil or grease and blocks dust, water, or particles. In food, process, or light manufacturing plants, it appears in equipment where cleanliness and uptime matter.
During installation, check that the shaft is within tolerance and free of burrs or marks on the sealing track. Make sure the housing is clean and not deformed. Lubricate the lip with the same oil or grease used in the equipment, then press it in with a flat driver to avoid twisting or damaging the spring. If the shaft is worn, consider a repair sleeve before fitting the new seal.
To get a quote for code 5423, send the shaft, housing, and height dimensions, plus a photo of the old seal or the drawing. We will find an alternative in the DBH line or another brand we carry. We can also confirm whether the Lx design suits your application based on lubricant type, speed, and operating temperature.
