The DBH 1220/85 oil seal is a single-lip radial seal that mounts on the shaft and inside the housing to retain oil or grease and stop dust and water from entering. Its A 120 design combines a total height of 7 mm in the lip area with 10.70 mm in the outer body, which improves stability in housings with little support. It is used in gearboxes, pumps, electric motors and transmission equipment operating at moderate speed.

This seal has a shaft diameter of 25 mm, a housing diameter of 50 mm and a height of 7.00/10.70 mm. The A 120 design corresponds to a radial seal with a sealing lip and a stepped outer body: the 7 mm section seats in the housing and the 10.70 mm section provides a larger centering surface. The lip runs on the shaft with controlled interference to maintain contact without generating overheating.

It is used in equipment with continuous rotation and the presence of lubricant: gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. It also appears in agricultural and industrial applications where the environment has dust or moisture and a simple, reliable barrier is needed. It is a wear part that should be checked when an oil leak or persistent drip appears.

To mount it, check that the shaft is clean, free of burrs and machining marks, and that the sealing surface has suitable roughness. Lubricate the lip before inserting it and place the seal with a tube or press that bears on the metal edge, never on the lip. If the housing has a shoulder, respect the depth so that the lip does not sit outside the track. Correct alignment prevents premature leaks.

If you need a nearby size or an equivalent from another brand, send us the full part number, the shaft diameter and the housing diameter. With that data we can look for an alternative with the same A 120 design or similar, always confirming dimensions against the manufacturer's data sheet. We can also advise you if the original seal has a different height or if the housing accepts a variant with an additional lip.
