The DBH 5189Vit seal is a radial shaft seal of 40 mm shaft, 60 mm housing and 10 mm height, with Lx design. It is used to retain lubricant and exclude contaminants on rotating shafts, inside gearboxes, pumps, electric motors and transmission equipment. Its elastomer lip runs on the shaft and its metal case is press-fitted into the housing. It is a wear part: choosing the right size and design prevents leaks and unplanned downtime.

This item is a DBH 5189Vit radial shaft seal, identified by its designation and by the dimensions shown in the data sheet: shaft (d) 40 mm, housing (D) 60 mm and height (h) 10 mm. The Lx design corresponds to a single-lip seal with spring, with an outer metal case and elastomer lip, intended for press-fit mounting in the housing and direct contact on the shaft. It is a dynamic sealing part, not a structural component: its function is to contain the oil or grease and slow the entry of dust and water.

Typical applications for a seal of these dimensions appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. It is also found in machine tools, conveyors and process equipment where a shaft rotates inside a lubricated housing. In all those cases the seal closes the lubricant chamber and protects the bearings or bushings behind it, extending their service life.

To mount it, verify that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or press that bears on the case, never on the lip. When selecting a replacement, take into account the shaft dimension, the housing diameter and depth, the type of lubricant and the rotation speed. If the shaft is worn, consider a repair sleeve or a seal with an alternative-size lip.

If you need an equivalent or a nearby size, send us the code 5189Vit along with the shaft, housing and height dimensions, and a photo of the old seal if you have it on hand. With that data we verify whether there is a variant of the same series or from another brand that fulfills the function. We can also advise you if the Lx design is not suitable for your application and it is better to switch to another type of lip or case.
