The DBH 8931 radial shaft seal is a lip seal that mounts on the shaft and blocks the passage of oil, grease or contaminants in gearboxes, pumps and motors. Its Lx design combines a sealing lip with a metal case that fits into the housing. With a 55 mm shaft diameter, 75 mm housing diameter and 8 mm height, it is a common size in power transmission equipment. MR Accesorios Industriales offers it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified by the code 8931. Its dimensions are 55.00 mm shaft diameter (d), 75.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and outer case, designed to be press-fitted into the housing with the lip resting on the shaft. It is a standard replacement part within the seals and oil seals category.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles. In environments with vibration or moderate temperature, the lip maintains contact with the shaft and extends the service life of nearby bearings and gears.

To correctly select a seal, verify that the shaft and housing diameters match the indicated values. The 8.00 mm height must fit into the cavity without deforming. During installation, lubricate the lip with the same oil or grease used in the equipment, insert the seal perpendicularly and avoid striking the lip. If the shaft shows wear, consider a repair sleeve or an alternative size.
