The DBH 5721 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its standard dimensions —58.74 mm shaft, 82.58 mm housing and 12.70 mm height— make it suitable for gearboxes, pumps and power transmission equipment where the mounting space is defined by standard. MR Accesorios Industriales supplies this official brand and advises you so you choose the correct seal for your application.

The DBH 5721 is a seal with an Lz design, with the dimensions shown on its product page: shaft diameter 58.74 mm, housing diameter 82.58 mm and height 12.70 mm. The Lz design corresponds to a seal with a sealing lip and metal body, designed to be press-fitted into the housing and seal against the moving shaft. These are the dimensions you need to verify before ordering: any variation in shaft or housing diameter prevents correct mounting.

Typical applications for this type of seal include gearboxes, centrifugal pumps, electric motors and power transmission equipment. In all cases, the function is the same: prevent oil or grease leakage and stop the ingress of dust, water or particles that accelerate wear on bearings and gears. Due to its size, the 5721 usually appears in medium-sized equipment, where the shaft rotates at moderate speeds and the operating temperature is not extreme.

To select the correct seal, in addition to the dimensions, take into account the type of lubricant, the peripheral shaft speed and the service temperature. A lip unsuitable for those conditions can harden or wear prematurely. During mounting, verify that the housing is clean and free of burrs, lubricate the lip before inserting the shaft and avoid striking it: use a tube or spacer that presses on the outer ring, never on the lip.

If you cannot find part number 5721 or need a nearby size, send us the dimensions of your seal —shaft, housing and height— or a photo of the part. With that data we can look for the equivalent in the same brand or in another line we supply. We can also advise you if the Lz design is not the most suitable for your equipment and another lip or material configuration should be evaluated.
