The DBH 6686Pol radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and water at the point where a shaft rotates inside a housing. Its Lz-R design combines a main lip with a secondary exclusion lip, which makes it suitable for equipment exposed to dirt. It is used in gearboxes, pumps, electric motors and industrial transmissions. MR Accesorios Industriales carries this brand and quotes it via WhatsApp.

This item is a DBH 6686Pol radial shaft seal with the following dimensions: shaft diameter 47.63 mm, housing diameter 64.95 mm and height 8.28 mm. The indicated design is Lz-R, which corresponds to a seal with a main sealing lip and a secondary exclusion lip, intended to retain lubricant and slow the advance of contaminants from the outside. Code 6686Pol identifies this size and configuration within the DBH line.

Its typical applications appear in equipment with continuous rotation and the presence of dust or moisture: gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain transmissions. It is also found in road and agricultural machinery and in food processing lines, provided the shaft and housing have the indicated dimensions. In all those cases it fulfills the dual function of retaining lubricant and protecting bearings from the entry of particles.

To mount it, verify that the shaft is within the recommended tolerance for radial shaft seals, free of burrs or marks that could damage the lip, and that the housing has the appropriate diameter and finish. Lubricate the lip with the same grease or oil as the equipment before inserting it, and do so with a support tube that pushes on the outer diameter, never on the lip. If the equipment works with a lot of dirt, the secondary lip of the Lz-R design helps, but it is advisable to check the condition of the shaft and replace the seal at the first sign of leakage.
