The DBH 8426 oil seal is a single-lip radial seal that mounts on the shaft and inside the housing to contain lubricant and block the entry of dust, water or particles. Its A 103 design and stepped height from 8 to 12.50 mm make it suitable for equipment with deep housings or replacement seals of different heights. It is used in pumps, electric motors, reducers and transmission machinery operating with 56 mm shafts.

This DBH 8426 seal has a shaft diameter of 56 mm, a housing diameter of 73 mm and a height ranging from 8.00 to 12.50 mm. The A 103 design corresponds to a single-lip seal with a metal case and sealing lip, designed to retain oil or grease in moderate-rotation applications. The variable height covers housings where the original seal is 8 mm or up to 12.50 mm, without the need to modify the machining.

Typical applications for this seal include centrifugal pumps, electric motors, gearboxes, conveyor rollers and power transmission equipment. In all these cases, the DBH 8426 seal seals the passage of lubricant to the outside and prevents the entry of contaminants that accelerate wear on bearings and bushings. It is a frequently replaced part in preventive maintenance at industrial plants.

To install the DBH 8426 seal, check that the shaft is 56 mm and the housing is 73 mm, with no burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and tap gently on the case, never on the lip. The height of 8.00/12.50 mm allows you to choose the mounting position according to the housing depth. If the shaft shows wear, consider a repair sleeve.

If you need a seal with equivalent dimensions or a different height, you can ask about the code 8426 and we will help you find the variant that fits your equipment. We can also look for alternatives from other brands or with a different lip design, always respecting the shaft and housing dimensions.
