The DBH 5473 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment where a rotating shaft exits a lubricated body. With 98.4 mm shaft diameter, 120.62 mm housing and 14.28 mm height, it is a replacement size for equipment that already has a machined housing.

This item is a seal from the DBH line, identified by part number 5473. Its dimensions are 98.4 mm shaft diameter (d), 120.62 mm housing diameter (D) and 14.28 mm height (h). The Lz design corresponds to a single lip with spring, intended for rotating shafts with internal lubrication. The DBH brand is an official brand that MR supplies, so the replacement part is ordered with the exact part number and the dimensions in the registry.

Typical applications for a seal of this size are in equipment with medium-section shafts: reducers and gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing contaminants from entering from outside. It is also used as a closure in bearings and housings that work in dusty or humid environments.

To install it, verify that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. The seal is inserted with the lip facing the lubricated side, and it is advisable to use an installation tool that presses on the metal edge, never on the lip. If the shaft shows a marked groove, consider replacing the seal with a size that positions the lip elsewhere or consult MR to review alternatives.

If you need an equivalent or a nearby size, the most practical approach is to send part number 5473 together with the shaft and housing dimensions. With that data, a seal from another brand or series that performs the same function can be found, always respecting the diameters and height. You can also send a photo of the old part or the housing to confirm the design and avoid installation errors.
