The DBH 1112 radial shaft seal is a lip seal designed to close off lubricant passage and prevent contaminant ingress 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 seal has a shaft diameter of 38 mm, a housing diameter of 54 mm 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 double 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 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 correctly select a seal such as the DBH 1112, 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 cavities of different depths, but it is important that the lip rests on a ground surface without grooves. During installation, lubricate the lip with the same oil or grease as the equipment and use an installation tool to avoid damaging it. Avoid striking the seal directly.
