The DBH 5539 is a radial shaft seal built to keep lubricant inside a housing and keep dust, water and other contaminants out. Its three key measurements are a 44.45 mm shaft, a 60.30 mm housing bore and an 11.11 mm height, and it uses the Mz design. You will find seals of this type on gearboxes, pumps and other rotating equipment. MR Industrial Accessories supplies this brand and can help you match the seal to your application.

The part number 5539 belongs to the DBH line of radial shaft seals. Reading the size is straightforward: 44.45 mm is the shaft diameter the lip runs on, 60.30 mm is the bore diameter it presses into, and 11.11 mm is the overall height. The Mz designation describes how the lip and the metal case are put together, which matters when you compare a replacement against the seal you are removing.

A seal this size turns up in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission assemblies. Its job is twofold: it holds oil or grease in place and it keeps dust, water and particles from reaching the bearings and gears behind it. Because it is a low-cost component, replacing it on schedule is a practical way to protect the parts that are far more expensive to repair.

Before ordering, confirm the shaft, bore and height against your equipment. The Mz designation points to a particular lip and case geometry, so if the seal you pulled out carries a different code, check with us first. At installation, coat the lip with the same lubricant used in the unit, seat the seal squarely to the shaft and press it in without hammering on the lip. A torn lip or a scored shaft surface will leak again soon after.

If you are looking for an equivalent, the fastest route is to send part number 5539 or the dimensions you measured on the equipment. A photo of the old seal or of the housing also helps. With that information, MR Industrial Accessories reviews options within the DBH range and other brands we supply, then sends you a quote.
