When a rotating shaft needs reliable sealing in a tight radial space, the DBH 5432 oil seal is a common choice. This radial lip seal has a 12.70 mm shaft diameter, a 25.37 mm housing bore and a 6.35 mm overall width, and its Lx design indicates a single lip with a spring. MR supplies this brand and can quote the 5432 size for your maintenance or repair job.

The 5432 code identifies a specific size in the DBH oil seal line. The three critical dimensions are: shaft 12.70 mm, housing 25.37 mm, width 6.35 mm. The Lx configuration means a single sealing lip with a spring, intended for lubricated rotating shafts. Before ordering, confirm these measurements on the shaft and housing to ensure a correct fit.

Seals in this size range appear in compact equipment such as small electric motors, centrifugal pumps, worm gearboxes, fan shafts, machine tools and low-power transmission assemblies. They serve two purposes: keeping oil or grease inside and keeping dust, water and particles out. Because the seal runs against the shaft, its condition directly affects bearing and bushing life.

Proper installation makes a difference. Check that the shaft is within tolerance and free of burrs or grooves, and that the housing bore and depth are correct. Lubricate the lip with the same oil or grease used in the machine. Use a driver that presses on the outer edge of the seal, never on the lip. If the shaft shows wear, a seal with the lip positioned at a different depth may be an option.

If you need an equivalent, provide part number 5432 along with the shaft, housing and width dimensions, and a photo of the old seal if available. That information lets us review alternatives within the DBH line and other brands we carry. We can also help if the housing has a shoulder or if the original seal had a different lip design.
