The DBH 6725Pol oil seal is a single-lip radial seal that mounts on a 75 mm shaft and seals against a 100 mm housing, with a total height of 17 mm. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate the wear of bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment where the shaft rotates continuously.

The DBH 6725Pol is identified by its designation and by the dimensions shown on the product page: shaft diameter 75 mm, housing diameter 100 mm and height 17.00 mm. The Lx-R design corresponds to a single-lip seal with a spring, designed for rotating shafts with permanent lubrication. The DBH brand is a brand that MR carries, so the replacement part arrives with the manufacturer's traceability and not as a generic alternative.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all these cases the seal works on a shaft that rotates inside a fixed housing and must keep the oil or grease inside. It is also used as a barrier against dust in environments with chips or humidity, where an open seal is not enough.

To install it properly, check that the shaft has no burrs, scratches or wear in the contact area: a lip running on a damaged surface loses sealing within a few hours. The housing must be clean and free of dents, and it is advisable to lubricate the lip before inserting it. If the shaft has play or eccentricity, the seal does not compensate for that movement and the bearing support must be corrected before replacing it.

If you cannot find the 6725Pol or need a neighboring size, send us the part number and the shaft, housing and height dimensions. With that data we look for the equivalent in the same brand or in another line of radial shaft seals, respecting the Lx-R design. We can also evaluate variants with a double lip or a reinforced case if the equipment works under more demanding conditions.
