The DBH 6487Pol radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. It is mounted with an interference fit in the housing and its lip rests on the rotating shaft, so it retains the lubricant and at the same time blocks the entry of dust, water or particles. It is a wear part: when lubricant loss appears or the lip hardens, it is replaced with an equivalent size.

This item is identified by the designation 6487Pol and corresponds to a shaft seal with a 64 mm shaft (d), 80 mm housing (D) and 8.00 mm height (h). The indicated design is Lx-R, a lip configuration that runs on the shaft and seals against the housing. DBH is an official brand that MR carries, so the part number can be cross-checked against the manufacturer's product page to confirm the geometry before placing the order.

Seals of this size are used in gearboxes, pumps, electric motors, rollers and power transmission equipment where the shaft rotates inside a lubricated support. They also appear in agricultural machinery, conveyors and process equipment operating with dust or water present. In all these cases the function is the same: retain the lubricant inside the assembly and keep the environment from entering the bearing or bushing.

To install it, check that the shaft has no burrs or marks in the contact area and that the housing is clean and free of deformation. The lip is lubricated before inserting it and it is seated with a flat tool, never by striking the seal directly. If the shaft shows wear, it is worth evaluating a seal with the lip in a different position or a repair sleeve. Selection depends on the speed, temperature and type of lubricant in the equipment.

If you need a nearby size or an equivalent from another brand, send us the part number 6487Pol 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 look for the alternative within the DBH line or among the other brands we carry. We can also advise you if the Lx-R design is not the right one for your application.
