The DBH 9457 radial shaft seal is a lip seal that mounts on a 44 mm shaft and fits into a 68 mm bore, with a height of 8 mm. Its function is to retain lubricant inside the assembly and prevent dust, water or particles from entering from outside. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with rotating shafts. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your application.

The DBH 9457 is an Lx design oil seal, with a single sealing lip and a stainless steel spring that maintains pressure on the shaft. Its dimensions are 44 mm shaft diameter, 68 mm housing diameter and 8.00 mm height. The outer case is metal, suitable for press fitting into a rigid housing. This type of seal runs in direct contact with the shaft and requires a polished sliding surface to achieve effective sealing and long service life.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. It is also used in machine tools, conveyors and hydraulic systems where oil or grease must be contained and bearings protected from the environment. In all cases, the seal must be selected according to peripheral speed, operating temperature and the type of fluid to be retained.

For installation, check that the shaft has adequate hardness and finish, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the application before inserting it. The seal must enter perpendicular to the housing, without blows that deform the case. If the shaft is worn, consider a nearby size or a seal with an auxiliary lip. Correct alignment between shaft and housing is key to preventing premature leaks.
