The DBH 5890 is a radial shaft seal used to keep lubricant in and contaminants out of rotating equipment. With a shaft diameter of 52.4 mm, housing bore of 81 mm, and width of 11 mm, it fits a range of medium-duty gearboxes, pumps, and motors. MR Industrial Accessories supplies this seal and can help you confirm the correct size and design for your application.

This seal is identified by code 5890 in the DBH line. Its critical dimensions are: shaft 52.4 mm, housing 81 mm, and width 11 mm. The Lx design features a sealing lip with a metal case, intended for press-fitting into a housing bore. Depending on the version, a garter spring may be included to maintain lip contact on the shaft.

Typical applications include gearboxes, pumps, electric motors, and other equipment where a rotating shaft exits a lubricated cavity. The seal prevents oil or grease leakage and blocks dust, water, and other contaminants from reaching bearings or gears. In dirty or washdown environments, it serves as the first line of defense.

Before ordering, verify that the three dimensions match your shaft, housing bore, and available depth. The shaft surface should be smooth and free of nicks; wear on the sealing track can cause leaks even with a new seal. During installation, lubricate the lip with the system lubricant, press the seal squarely into the bore, and apply force only to the outer metal case, never the lip.

To request a quote for the DBH 5890, send the shaft, housing, and width dimensions, plus a photo of the old seal if available. The code on the seal or the equipment model also helps. MR Industrial Accessories can check for equivalents in the brands we supply and help you decide if the Lx design suits your application.
