The DBH 8501Pol radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 70 mm shaft diameter, 92 mm housing bore and 12 mm height make it suitable for equipment with medium-size shafts. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a key component for maintaining sealing integrity in gearboxes, pumps and motors.

This DBH 8501Pol radial shaft seal has an Lx-H design and is identified by its designation 8501Pol. Its dimensions are 70 mm shaft diameter (d), 92 mm housing bore (D) and 12.00 mm height (h). The sealing lip is shaped to run on rotating shafts, retaining oil or grease and blocking the ingress of dust and water. The typical construction of these seals combines a wear-resistant elastomer with a metal reinforcement that gives it rigidity for press fitting.

The most common applications of this radial shaft seal include gearboxes, reducers, centrifugal pumps, electric motors and conveyor rollers. In all cases, its function is to prevent lubricant leaks and protect the internal bearings from external contamination. Due to its size, it is common in general industrial power transmission equipment, where reliable sealing is required on shafts rotating at moderate speeds.

To correctly select a radial shaft seal, verify that the shaft, housing bore and height dimensions match those of your equipment's housing and shaft. The shaft surface must be clean, free of burrs and scratches, and have adequate hardness so as not to damage the lip. During installation, lubricate the lip with the same oil or grease you intend to retain and make sure the seal enters perpendicular to the housing. If the shaft shows wear, consider an adjacent size or a seal with an auxiliary lip.
