A radial shaft seal such as the DBH 5756 keeps lubricant where it belongs and keeps contaminants out. Its job is simple but critical: the lip rides against a turning shaft while the outer body stays fixed in the bore, forming the barrier between the inside of a machine and the surrounding environment. With a 19 mm shaft, 31.75 mm housing and 9.52 mm width, this seal suits compact equipment where there is little room along the shaft.

The reference 5756 identifies this seal within the DBH line. Reading the size is straightforward: the first figure is the shaft it runs on, 19 mm; the second is the bore it presses into, 31.75 mm; the third is the overall width, 9.52 mm. The Mz designation describes how the lip and the metal case are formed, so the seal seats in the cavity without distortion when it is driven in. When the old part carries the same 5756 marking, it can be swapped in as received.

You will find seals of this size on small centrifugal pumps, electric motors, gearboxes, compressors, fans and machine tools, as well as on belt and chain drives where oil has to stay on one side of the housing. In each case the seal does two things at once: it holds the lubricant in and it blocks dust, water and particles from reaching the bearings or bushings behind it.

Before ordering, confirm the three measurements against the shaft, the bore and the available width. The shaft surface deserves a look as well, since scoring or wear under the lip path will prevent a proper seal. On assembly, coat the lip with lubricant, keep the seal square to the shaft, and press on the metal case with a driver or sleeve rather than on the lip itself. For equipment running at elevated speed or temperature, ask about alternative lip materials.

For a quote, send the complete code along with the shaft, housing and width dimensions, and a photo of the seal being replaced. That information lets us check options in the DBH range and among the other seal lines we supply. If the Mz profile does not match the duty on your equipment, we can point you toward a different lip configuration.

Seals and oil seals form one of the product families MR Industrial Accessories supplies to customers throughout the United States and in several Latin American countries. Send the 5756 code on WhatsApp or by email and our team will come back with the technical details you need.
