The DBH 5942 is a radial shaft seal built to keep lubricant in and contamination out where a shaft turns. Its Mz design covers the lip geometry and mounting details that hold tightness in service. Three figures define the fit: shaft 54 mm, housing bore 76.12 mm, height 12.70 mm. Gearboxes, pumps and similar industrial equipment are the usual homes for this size. MR Industrial Accessories supplies the DBH line and helps you match the seal to the application.

Reading the code is the fastest way to confirm you have the right part. The 5942 designation identifies this seal, while the numbers that follow in the catalog listing describe the cavity it fills: 54 mm at the shaft, 76.12 mm at the housing bore, 12.70 mm tall. The Mz suffix points to a defined lip and mounting arrangement rather than a plain profile. When those three measurements line up with your equipment, the seal drops in as a direct replacement.

Where does a seal of this size show up? Gearboxes, centrifugal pumps, electric motors, conveyor rollers and general machinery with medium-diameter shafts. In each case the job is the same: hold oil or grease inside, block dust and water from the outside. A seal that is chosen correctly keeps lubricant where it belongs and helps avoid unplanned downtime.

Installation is straightforward but unforgiving of shortcuts. Wipe the shaft and housing clean and check for burrs or scratches before anything goes in. Lubricate the lip, then seat the seal squarely. Base your selection on the measured shaft and bore, plus the lubricant in use, the operating temperature and the rotation speed. The Mz configuration may call for a particular mounting direction, so check the manufacturer's data sheet if that is unclear.
