The DBH 5372 is a radial shaft seal with an Lz design, sized for a 64 mm shaft, an 85 mm housing bore and a 16 mm width. It keeps lubricant in and contaminants out where a shaft turns inside a fixed housing. Because the lip wears, replace it once it hardens or the shaft surface becomes scored, before oil loss reaches bearings and gears.

This oil seal carries the DBH brand and part number 5372. Its key measurements are 64 mm shaft, 85 mm housing and 16.00 mm height, and the Lz designation refers to a sealing lip with a standard mounting arrangement for rotating shafts. Use the 5372 reference when you compare spares or look up the item in a catalog.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. In food, chemical or water treatment service, the seal does two jobs: it holds oil or grease inside and keeps water and dust out of the bearing cavity. You will also find them on older machines where the housing bore is already marked, so check the fit before pressing in a new seal.

Choosing the right seal takes more than matching three dimensions. Inspect the shaft for wear, check surface roughness, verify housing concentricity and confirm the lubricant type. A scored shaft prevents the lip from seating evenly, and leakage can return within hours. When installing, coat the lip with the same grease or oil used in the equipment, press it in perpendicular to the shaft and avoid hitting it with pointed tools. If the housing is damaged, a repair sleeve is an option.

To request a quote for the 5372, send the dimensions of the old seal — shaft diameter, housing diameter and height — along with a photo of the part and the housing. With that information we can search for an equivalent in DBH or another brand we supply and confirm the alternative. We can also advise whether the Lz design suits your application or if a different lip profile would work better.
