The DBH 1153/85 is a radial shaft seal with a lip that sits between a rotating shaft and a fixed housing, keeping lubricant in and contaminants out. Its A 120 design and stepped height of 7.00 to 10.70 mm let it fit housings with a shoulder or accommodate different bore depths without changing shaft or housing dimensions.

The seal is identified by the DBH code 1153/85. It fits a shaft of 25 mm (d) and a housing of 48 mm (D). The height is 7.00/10.70 mm (h): the portion that presses into the housing measures 7 mm, while the outer lip extends to 10.70 mm. This stepped profile is what allows the same seal to work in more than one housing depth. The A 120 designation refers to a radial shaft seal with a sealing lip and a reinforcing body, made for rotating shafts that run with lubrication.

Typical installations include gearboxes, pumps, electric motors, speed reducers, rollers and transmission equipment. The goal is to stop oil or grease from escaping and to keep bearings protected from dust, water and other particles. You will find this seal in industrial machinery, process equipment, conveying systems and general maintenance work, as long as the shaft and housing match the stated dimensions and the contact surface is in good condition.

When selecting a replacement, confirm that the shaft diameter and housing diameter agree with the values above. The variable height helps when housing depths differ, but check that the lip will run on a track free of scratches or wear. Lubricate the lip before installation and use a tool that will not damage it; if the shaft has burrs or splines, cover them with a protector. Verify speed, temperature and fluid compatibility against the manufacturer's data sheet.
