The DBH 1231 radial shaft seal is a lip seal that is mounted in the housing of a piece of equipment to retain lubricant and prevent the entry of dust, water or particles. Its Lx design and its dimensions of 78 mm shaft, 110 mm housing and 13 mm height make it suitable for rotating shafts in pumps, motors, gearboxes and reducers. MR Accesorios Industriales supplies this brand and advises you so you choose the correct seal.

This item is a radial shaft seal of the DBH brand, identified with the code 1231. Its dimensions are 78 mm shaft diameter, 110 mm housing diameter and 13.00 mm height. The Lx design corresponds to a seal with a sealing lip and standard configuration for rotating shafts. It is manufactured in elastomer with metal reinforcement, although the specific properties of the compound are confirmed against the manufacturer's product page. It is a direct replacement part for equipment that requires reliable sealing under continuous rotation conditions.

Typical applications of a seal of these dimensions include centrifugal pumps, electric motors, gearboxes, rollers and transmission shafts. In all cases, its function is to contain the oil or grease inside the assembly and block the entry of external contaminants. It is also used in process equipment, agricultural machinery and conveying systems. As it is a wear component, it should be checked periodically and replaced when leaks or abnormal noises appear.

To install this seal correctly, check that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Pressure must be applied evenly on the outer ring, never on the lip. When selecting a replacement, take into account the rotation speed, the working temperature and the type of fluid. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
