A rotating shaft needs a barrier that keeps oil or grease where it belongs and keeps dust, water and particles out. That is the job of the DBH 5723 radial shaft seal, an Lz design lip seal sized for a 50.80 mm shaft, a 90.00 mm housing bore and a 12.70 mm height. It fits equipment such as pumps, gearboxes, electric motors and transmission assemblies built around those dimensions.

The part is listed under the number 5723 within the DBH line of radial shaft seals. Its three key measurements are the shaft diameter (d) at 50.80 mm, the housing diameter (D) at 90.00 mm and the height (h) at 12.70 mm. The Lz construction pairs a sealing lip with a configuration intended for rotating shafts running with lubricant present, including cases where there is moderate pressure or oil circulation.

Seals of this size turn up in centrifugal pumps, gearboxes, electric motors, transmission shafts and process equipment that runs continuously. In each case the seal keeps the lubricant contained inside the assembly while blocking contamination from the outside. Because it is a wear part, it is normally replaced once leakage or dirt ingress shows up.

During installation, confirm that the shaft and bore match the stated values, that the shaft surface is polished and free of burrs, and that the housing has a proper entry chamfer. Lubricate the lip before fitting, press the seal in perpendicular to the shaft, and avoid striking the lip directly. When the equipment runs with internal pressure, check that the seal design suits that condition.

For an equivalent from another brand, send part number 5723 or the three dimensions of the seal you are replacing: shaft diameter, housing diameter and height. With that information we can locate a match in our seals and oil seals range and advise on the design that best fits your lubricant and operating conditions.
