The DBH 8997 oil seal is a radial shaft seal with a 120 mm shaft diameter, 140 mm housing diameter and 12 mm height. Its Lx design makes it suitable for rotating shafts where lubricant must be contained and dust or water ingress blocked. It is used in gearboxes, pumps, electric motors and power transmission equipment operating at moderate speeds that require reliable, low-maintenance sealing.

This item is a radial shaft seal from the DBH brand, identified by part number 8997. Its dimensions are 120 mm shaft diameter (d), 140 mm housing diameter (D) and 12.00 mm height (h). The Lx design corresponds to a single sealing lip with spring, intended to retain lubricant in applications where the shaft rotates and the housing remains fixed. The lip elastomer runs on the shaft and the metal case fits into the housing.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the seal prevents oil or grease leaks and protects the bearings from external contaminants. It is a wear part that should be replaced when leaks or abnormal noise are detected in the sealing area.

To install the seal, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same service oil or grease before inserting it. Place the seal perpendicular to the shaft and press with a tube of suitable diameter until it seats at the bottom of the housing. Avoid striking the lip and make sure the spring is correctly positioned. If the shaft shows wear, consider a nearby size or a seal with an additional lip.
