The DBH 5409/85 radial shaft seal is a lip seal mounted on a rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions — 31.75 mm shaft, 44.50 mm housing and 9.52 mm height — correspond to a compact size widely used in equipment with 1 1/4 inch shafts. MR Accesorios Industriales supplies this official brand for industrial replacement and maintenance.

The DBH 5409/85 is an Lx design oil seal, with the three dimensions that define its mounting: shaft diameter 31.75 mm, housing diameter 44.50 mm and height 9.52 mm. The Lx design corresponds to a single-lip seal with a metal case and sealing lip, intended for rotating shafts with lubrication. These dimensions are the ones you need to verify before ordering: the shaft diameter, the housing diameter and the available depth in the housing.

Seals of this size are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil or grease must be contained and external contamination kept out. They also appear in agricultural machinery, washing equipment and conveying systems. Whenever a shaft rotates inside a housing and the lubricant must be separated from the environment, this type of seal performs that function.

To select the correct seal, in addition to the dimensions, take into account the shaft speed, the working temperature and the type of lubricant. The lip must rest on a ground shaft surface free of grooves; if the shaft is worn, it is advisable to evaluate a repair sleeve or a nearby size. When mounting it, lubricate the lip, check that the spring is on the fluid side and fit the seal perpendicular to the shaft, without striking it unevenly.
