The DBH 9157 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 38 mm shaft, 74 mm housing and 8 mm height, and Lx design, it is a common size in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales carries this brand and will quote it to you on WhatsApp.

The DBH 9157 is a radial shaft seal from the DBH line, with the following dimensions: shaft diameter d 38 mm, housing diameter D 74 mm and height h 8.00 mm. The Lx design corresponds to a seal with a sealing lip and a construction configuration specific to the series; to confirm details of the lip, the elastomer material and the spring, check the manufacturer's product page. These are the dimensions you must verify against the shaft and housing before mounting.

Typical applications for a seal of this size include centrifugal pumps, electric motors, gearboxes, conveyor rollers and power transmission equipment. In all cases it serves to retain the oil or grease inside the assembly and prevent the entry of external contaminants, extending the service life of bearings and gears. It is a wear part that should be replaced when lubricant leakage appears or play or wear is detected on the lip.

For mounting, verify that the shaft is clean, free of burrs and marks, and that the sealing surface has the proper hardness and roughness. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and install the seal perpendicular to the shaft, without striking it directly on the lip. If the housing shows wear, consider using a seal with a larger outer diameter or a repair sleeve. The choice of lip material depends on the temperature and the fluid to be retained.
