The DBH 1153/85 oil seal is a lip-type radial seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its A 120 design and variable height of 7.00 to 10.70 mm make it suitable for housings with a shoulder or for covering different housing depths without changing the shaft or bore diameter.

This item is identified by the DBH designation 1153/85 and runs on a shaft of 25 mm diameter (d), inside a housing of 48 mm (D). The mounting height is 7.00/10.70 mm (h), meaning the seal has a stepped profile: the part that enters the housing measures 7 mm and the outer lip reaches up to 10.70 mm. The A 120 design corresponds to a radial shaft seal with a sealing lip and reinforcing body, intended for rotating shafts with lubrication.

It is used in gearboxes, pumps, electric motors, reducers, rollers and transmission equipment where oil or grease leaks must be prevented and bearings protected from the environment. It is commonly found in industrial machinery, process equipment, conveying and general maintenance, provided the shaft and housing have the indicated dimensions and the contact surface is in good condition.

To select it, verify that the shaft diameter and housing diameter match the values on the product page. The variable height allows it to be adapted to housings of different depths, but it is advisable to check that the lip rests on a track free of scratches or wear. Installation is done with the lip lubricated and a tool that does not damage it; if the shaft has burrs or splines, use a protector. Speed, temperature and fluid type are confirmed against the manufacturer's data sheet.
