The DBH 5527Sil is a radial shaft seal with a single lip and a metal spring, sized for a 36 mm shaft. It keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching the bearing cavity. The seal presses into a 54 mm bore with a 7 mm height. You will find it in pumps, motors, gearboxes and other power transmission assemblies that run under continuous industrial duty.

This seal carries the Mz design designation. Its three key dimensions are: shaft 36 mm, housing 54 mm, height 7.00 mm. A garter spring keeps the lip in steady contact with the shaft, so minor misalignment or normal shaft wear does not break the sealing line. The outer shell is an elastomeric compound that stands up to the oils and greases typically found in industrial equipment. When the original seal reaches the end of its service life, this part drops into the same cavity.

Common installation points include centrifugal pumps, low and medium power electric motors, speed reducers, transmission shafts and process equipment that runs continuously. Machine tools, compressors and centralized lubrication systems also use this size. In every case the goal is the same: keep contaminants out of bearings and gears, and keep oil from escaping where it can affect the assembly's performance or service life.

Selection starts with the three dimensions. Measure the shaft, the housing bore and the height, and compare them with the values above. The Mz code reflects a specific lip and body configuration; if your original seal uses a different design, check with us before substituting. At installation, coat the lip with the same oil or grease used in the equipment, push the seal in squarely to the shaft, and avoid impacts. A seal that goes in crooked or gets nicked during fitting can leak early or fail at the lip.

If the exact size is not available or you need a cross-reference, we can help you identify an alternative. Send the part number 5527Sil or the dimensions of your current seal (shaft, housing and height) and we will advise you. We work with the DBH line and other brands, and we can also quote alternative designs.
