For rotating shafts that need reliable sealing, the DBH 5127 oil seal offers a 42 mm shaft size, 72 mm housing bore and 10 mm width. Its Lz configuration includes both a sealing lip and a dust lip, so it keeps lubricant in and contaminants out. You will find it in gearboxes, pumps, electric motors and other power transmission equipment. MR supplies this brand and can help you confirm the right seal for your machinery.
The DBH 5127 is a radial shaft seal. The code 5127 identifies the specific size and design. The three critical dimensions are 42.00 mm for the shaft (d), 72.00 mm for the housing (D) and 10.00 mm for the height (h). The Lz design means the seal has a main sealing lip plus an additional dust lip. The elastomer body and the internal spring work together to keep the lip in contact with the shaft, even when minor misalignment occurs.
You will typically find this seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission components. Its job is to stop oil or grease from escaping while blocking dust, water and particles that would otherwise damage bearings and gears. Because it is a wear part, replace it whenever you see a leak or when the equipment is taken apart for service.
When installing a radial shaft seal, first verify that the shaft and housing dimensions match the values above. The shaft surface should be clean and free of burrs or deep grooves. Lubricate the lip before pressing it in. Insert the seal perpendicular to the shaft using a tool that presses on the outer edge, never on the lip. If the shaft is worn, a repair sleeve can help restore the sealing surface.
If you need a different size or an equivalent, send the full part number along with the shaft, housing and height dimensions. A photo or sample of the original seal also helps. With that information, we can search for an alternative within the same brand or another line we carry. We can also advise on the appropriate elastomer or design based on your operating temperature, speed and fluid.
