The DBH 8405 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating shafts. Its designation 8405 corresponds to a seal with a 56 mm shaft diameter, 75 mm housing diameter and a height of 8.00/12.50 mm, with A 103 design. It is used in gearboxes, pumps, electric motors and power transmission equipment, where it seals between the shaft and the static housing.

This item is a radial shaft seal from the DBH line, identified with code 8405. Its dimensions are shaft (d) 56 mm, housing (D) 75 mm and height (h) 8.00/12.50 mm. The A 103 design corresponds to a seal with a sealing lip and metal body, suitable for retaining oil or grease in applications with rotary motion. The double height means the lip can be mounted in two positions, which makes installation easier depending on the available space. It is a common replacement part in industrial equipment.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors, drive shafts and machinery rollers. In all these cases, the 8405 seal protects bearings and gears from dust, water or particles, and prevents lubricant leaks. It is often found in equipment in the food, chemical, cement and material handling industries, where cleanliness and reliability are critical.

To install a radial shaft seal, check that the shaft and housing are clean, with no burrs or marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Insert the seal perpendicularly, without hitting the lip, using a tube or shim that rests on the outer ring. Selection must take into account shaft speed, working temperature and the type of fluid. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
