The DBH 1248 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and water in rotating equipment. It mounts on a 50 mm shaft and fits into a 72.5 mm bore, with a height of 11 to 16 mm depending on the A 053 design. It is a key component in gearboxes, pumps and motors, where proper sealing extends bearing life and prevents downtime.

This DBH 1248 oil seal has a shaft diameter of 50 mm, a housing diameter of 72.5 mm and a height that varies between 11 and 16 mm depending on the A 053 design. The sealing lip is designed to work on the rotating shaft and maintain tightness in both directions. The typical construction combines an outer metal ring, an oil-resistant elastomer and a spring that ensures lip pressure. It is a common replacement part in equipment that operates with lubricant and requires protection against external contaminants.

It is used in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. It also appears in agricultural machinery, conveyors and hydraulic systems where there is continuous rotation and the presence of oil or grease. In all these cases, the seal prevents lubricant from escaping and dust or water from entering, protecting bearings and gears. It is a wear part that should be replaced when leaks or abnormal noises are detected.

To select the correct seal, verify that the shaft and housing dimensions match those of the equipment. The 11/16 mm height indicates that the A 053 design can be mounted in housings with different depths, as long as the lip rests correctly on the shaft. During assembly, lubricate the lip with the same oil as the equipment, avoid impacts and make sure the shaft has no burrs or wear. If the shaft shows a marked track, consider replacing it or using a seal with the lip in a different position.
