The DBH 1112 radial oil seal is a lip seal designed to block the passage of lubricant and prevent the ingress of contaminants in rotating equipment. Its A 109-R H design combines a sealing lip with a dust lip, making it suitable for environments with dust or dirt. It mounts on 38 mm shafts and fits into 54 mm bores, with a height of 9.00/15.50 mm that allows it to adapt to different housing depths.

This DBH 1112 oil seal has a 38 mm shaft diameter, a 54 mm housing diameter and a height of 9.00/15.50 mm. The A 109-R H design indicates a configuration with a sealing lip and an auxiliary exclusion lip, mounted on a metal ring that gives it rigidity. The dual height (9.00/15.50 mm) suggests that the seal can be installed in housings with or without a shoulder, covering a range of depths. It is a common replacement part in pumps, electric motors and gearboxes.

Typical applications for this oil seal include transmission shafts, centrifugal pumps, electric motors, gear reducers and continuous process equipment. Its double lip makes it suitable for environments where dust, fine chips or moderate humidity are present, since the dust lip retains particles before they reach the main lip. It is also used in agricultural and industrial machinery operating with oil or grease lubrication.

To select an oil seal such as the DBH 1112 correctly, verify that the shaft diameter and housing diameter match the indicated dimensions. The 9.00/15.50 mm height allows it to be mounted in bores of different depths, but it is important that the lip rests on a ground surface free of grooves. During assembly, lubricate the lip with the same oil or grease used in the equipment and use an installation tool to avoid damaging it. Avoid striking the seal directly.
