The DBH 9428 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 44 mm shaft diameter, 72 mm housing diameter and 8.00 mm height make it suitable for gearboxes, pumps and power transmission equipment. DBH is a brand that MR carries, with technical support to select the material and lip type according to the application.

This item is a DBH 9428 radial shaft seal, identified by its numeric designation. According to the product page data, it has a shaft diameter of 44 mm, a housing diameter of 72 mm and a height of 8.00 mm. The Lx design corresponds to a single lip with spring, intended for rotating shafts with lubrication. The elastomer and the spring are confirmed against the manufacturer's product page at the time of quoting.

Radial shaft seals of this size are used in applications where the shaft passage through a housing must be sealed: gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. They also appear in agricultural and industrial machinery operating with dust, water or oil. The function is twofold: prevent lubricant leaks and stop the entry of particles that wear bearings and bushings.

To install a seal, verify that the shaft and housing diameters match the product page values, and that the shaft surface is clean and free of burrs. Lubricate the lip before inserting the seal, and the installation tool must rest on the outer edge, never on the lip. If the shaft shows wear, a seal with an offset lip can be evaluated. Speed, temperature and the fluid to be retained define the lip material.

If you need a seal equivalent to the DBH 9428, the most practical approach is to send the part number and dimensions to the MR Accesorios Industriales WhatsApp. We can also look if the shaft or housing have tolerances outside the standard. For that, it is best to provide the available shaft diameter, housing diameter and width, plus a photo of the housing and the old seal. With that data, the DBH or other brand alternative that MR carries is quoted.
