The DBH 1231 radial shaft seal is a lip seal that mounts 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 sells this brand and advises you so you choose the correct oil seal.

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

Typical applications for an oil seal of these dimensions include centrifugal pumps, electric motors, gearboxes, rollers and drive 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 inspected periodically and replaced when leaks or abnormal noises appear.

To install this oil 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, working temperature and type of fluid. If the shaft shows wear, consider an oil seal with an auxiliary lip.
