This item is a DBH 8125 radial shaft seal, identified by its designation 8125. Its dimensions are 28.00 mm shaft diameter (d), 42.00 mm housing diameter (D) and 7.00 mm height (h). The Lz design corresponds to a single sealing lip with spring, intended for rotating shafts with lubrication. The elastomer and the internal spring work together to maintain contact on the shaft and compensate for small misalignments.

It is used in applications where oil or grease must be retained and the entry of dust, water or particles prevented. It is common in gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. It also appears in agricultural machinery, conveyors and industrial equipment in general, where the oil seal protects bearings and gears from premature wear due to contamination.

To install it, verify that the shaft diameter and the housing match the indicated dimensions. The shaft must be clean, without burrs or marks, and it is advisable to lubricate the lip before inserting it. The oil seal is placed with the lip facing the side of the fluid to be retained. If the shaft shows wear, evaluate a seal with an auxiliary lip. The selection depends on speed, temperature and type of lubricant.
