When a rotating shaft needs its lubricant held in place and outside contamination kept away, a radial shaft seal like the DBH 5726 does that job. The Lz configuration combines a sealing lip with a spring, and the dimensions are shaft 50.80 mm, housing 92.00 mm and height 12.70 mm. MR supplies this brand and can help you confirm the right seal for the equipment.

The 5726 is the ordering number for this radial shaft seal within the DBH line. Reading the size is straightforward: the first figure refers to the shaft it runs on, the second to the bore it presses into, and the third to its overall height. In this case that means 50.80 mm, 92.00 mm and 12.70 mm respectively. The Lz designation describes a lip-and-spring layout, which is the common choice for retaining oil or grease on a turning shaft. Maintenance departments often keep this number on hand because it shows up as a replacement item in many assemblies.

You will find seals of this type in gearboxes, centrifugal pumps, electric motors, rollers and other transmission equipment. Their role is always the same: hold the lubricant where it belongs and stop dust, water or particles from reaching the bearings. A shaft close to 50.8 mm is typical of process machinery, conveying systems and treatment plants, which is why this size appears frequently in those settings. It is also useful on older equipment where sourcing the original size can be difficult.

Installation calls for a few basic checks. Make sure the shaft is free of burrs and wear, and that the housing bore is clean and not deformed. Apply lubricant to the lip before pressing the seal in, and keep it square to the shaft rather than driving it with direct hammer blows. Selection depends on shaft speed, operating temperature and the fluid being retained. If the shaft shows a deep groove, an auxiliary lip or a wear sleeve may be the better route. Treat Lz as a guide and confirm compatibility with the actual equipment.

If you are looking for something equivalent to the 5726, send the complete part number along with the shaft, housing and height measurements, plus a photo of the old seal. With that information we can search other brands or series that share the same critical dimensions, and advise on lip type and material based on the fluid and working temperature. Having the exact number is helpful but not essential, since the dimensions alone usually let us locate a match.
