The DBH 5364 oil seal is a single-lip radial shaft seal that mounts on the shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 55.56 mm shaft, 82.58 mm housing and 12.70 mm height make it suitable for equipment with medium-size shafts. It is a wear part: when the lip loses its elasticity or the shaft shows a marked track, it should be replaced to prevent leaks and contamination.

The DBH 5364 is a radial shaft seal with an Lz design, with the dimensions shown on its product page: 55.56 mm shaft diameter, 82.58 mm housing diameter and 12.70 mm height. The Lz design corresponds to a seal with a sealing lip and metal body, intended for rigid housings and rotating shafts. The 5364 nomenclature identifies the exact size within the DBH line, so when ordering it is best to mention the full part number to avoid confusion with neighboring sizes.

This type of seal is used in gearboxes, pumps, electric motors, rollers and power transmission equipment where oil or grease must be separated from the environment. It also appears in agricultural machinery, conveyors and process equipment. The combination of dimensions —55.56 mm shaft by 82.58 mm housing— is common in medium-size equipment, where the seal works at moderate speeds and with permanent lubrication. If the equipment operates with a lot of dust or water, the seal performs a double function: it retains the lubricant and slows the entry of contaminants.

To install it, check that the housing is clean, free of burrs or old sealant residue, and that the shaft has no splines or wear in the contact area. The lip is lubricated before inserting and is seated with a tube of the appropriate diameter, never with direct blows on the seal. The 12.70 mm height defines the space available in the housing: if the previous seal had a different height, confirm that the cavity accepts this dimension. In applications with a scored shaft, consider a wear sleeve or a seal with an auxiliary lip.

If you need a neighboring size or an equivalent from another brand, send us the 5364 part number and the housing and shaft dimensions. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also guide you if the original seal has a different designation but matches in diameters and height. The more complete the equipment information —brand, model and seal location— the faster we can give you a compatible option.
