The DBH 8425/85 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 22 mm shaft, 36 mm housing and a height of 7.50/11.50 mm, it is used in gearboxes, pumps and electric motors. Its A 090 design combines a sealing lip with an auxiliary exclusion lip, which improves protection in dusty or dirty environments. It is a key part for maintaining the service life of bearings and gears.

This DBH 8425/85 oil seal has a shaft diameter of 22 mm, a housing diameter of 36 mm and an overall height of 7.50/11.50 mm. The A 090 design corresponds to a seal with a main sealing lip and a secondary exclusion lip, mounted on a metal body with an outer coating. The designation 8425/85 identifies the combination of dimensions and the construction type. It is a standard replacement part for shafts rotating at moderate speeds that require oil or grease containment.

Typical applications include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In these systems, the seal prevents lubricant leaks and blocks the ingress of dust, water or particles that accelerate wear on bearings and gears. It is also used on fan shafts, compressors and machine tools where a reliable barrier is needed between the lubricated interior and the external environment.

To correctly select this seal, verify that the shaft diameter is 22 mm and the housing is 36 mm, with a housing depth compatible with the 7.50/11.50 mm height. The A 090 design is suitable when there is exposure to contaminants, since the auxiliary lip protects the main lip. During installation, lubricate the lip with the same oil or grease used in the equipment, avoid impacts and make sure the shaft has no burrs or grooves. If the shaft shows wear, consider a repair sleeve.

For that, send us the part number 8425/85 or the exact shaft, housing and height dimensions, along with a photo of the old part if possible.
