For rotating shafts that need to keep lubricant in and contaminants out, the DBH 5408 radial shaft seal offers a single-lip, spring-loaded solution. Its Lz lip design and dimensions—28.6 mm shaft, 44.4 mm housing, 11.11 mm height—suit gearboxes, pumps, motors, and other power transmission equipment where dependable sealing matters.

The DBH 5408 is a radial shaft seal, also called an oil seal. Its size is defined by three measurements: a 28.6 mm shaft diameter (d), a 44.4 mm housing bore (D), and an 11.11 mm overall height (h). The Lz designation indicates a single lip with a spring, built for rotating shafts that run with oil or grease. The elastomer lip and metal case form a dynamic seal that can handle small shaft misalignments.

You will find this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and similar power transmission assemblies. Its job is to hold lubricant inside the housing while blocking dust, water, and other particles from entering. Because the lip wears over time, replace the seal when you notice leaks or unusual noise around the sealing area.

Proper installation extends seal life. Clean the shaft and housing, and remove any burrs or scratches. Apply a light coat of the same lubricant used in the equipment to the lip before pressing the seal in. Keep the seal perpendicular to the shaft and avoid hitting the lip directly; use a tube or driver that presses on the outer edge. If the housing has a shoulder, set the seal to the correct depth without forcing it.
