Part number DBH 5797 is a radial lip seal built to hold lubricant in and keep contaminants out of rotating shaft assemblies. It measures 38.10 mm at the shaft, 69.85 mm at the housing bore and 11.90 mm in height, so it fits equipment where axial room is tight. The Mz designation points to a seal with a main retaining lip plus a secondary dust lip, a setup that adds protection in dirty or damp surroundings. Pumps, gearboxes and electric motors are typical places this seal shows up as a replacement item. MR Industrial Accessories LLC supplies this brand and can help match the seal to your application.

Reading the code helps with selection. The 5797 number fixes both the size and the design within the DBH line, while Mz tells you the lip arrangement. Shaft 38.10 mm, housing 69.85 mm, height 11.90 mm: check all three against the shaft and bore before you order, since a mismatch at any point will cause problems at startup.

Seals of this type sit in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. Their job is to keep oil or grease where it belongs and to block dust, water and other outside matter from reaching bearings and gears. They also appear in automotive and general industrial work where dependable sealing at moderate speeds matters. Lip compound and spring choice depend on the operating temperature and the fluid being contained, so it pays to review service conditions first.

During installation, inspect the shaft for burrs, nicks or scratches that could cut the lip. Coat the lip with the same oil or grease it will seal, and make sure the bore is clean and free of old sealant. The 11.90 mm height has to sit correctly in the housing depth so the seal is not distorted. On a worn shaft, an offset lip or a repair sleeve is worth considering. Shaft-to-bore concentricity is what keeps leaks from starting early.

If you need the same dimensions in another configuration, or a variant from the same series, send part number 5797 or the measurements of your sample. Alternatives from other brands are also an option when the Mz design does not fit the job.
