The DBH 8311Pol oil seal is a single-lip radial shaft seal designed for rotating shafts with a diameter of 80 mm. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles that could damage bearings and gears. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains dynamic contact. It is a key component in pumps, electric motors, gearboxes and industrial equipment in general.

This oil seal from the DBH brand is identified by the code 8311Pol and corresponds to an Lx-R design. Its dimensions are: shaft diameter (d) 80 mm, housing diameter (D) 96 mm and height (h) 9.00 mm. The sealing lip is oriented toward the side of the fluid to be retained, and its typical construction combines an outer metal ring with an elastomer that ensures sealing. It is a standard replacement part for shafts rotating at moderate speeds that require a reliable barrier against leaks.

The most common applications of this oil seal include centrifugal pumps, electric motors, gearboxes, compressors and transmission equipment. In all these cases, the oil seal protects bearings and gears from the ingress of contaminants and prevents the loss of oil or grease. It is also used in agricultural machinery, construction equipment and process lines where cleanliness and lubrication are critical to component service life.

To correctly select an oil seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The Lx-R design indicates a lip configuration that may vary by manufacturer; therefore, it is always advisable to confirm the orientation and the elastomer material. During assembly, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular to the shaft and avoid striking it so as not to damage the lip. If the shaft shows wear, consider a repair or the use of an oil seal with a wear sleeve.
