The DBH 1306/85 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil or grease in gear reducers, pumps and rotating equipment. Its A 429 design combines a sealing lip with a dust lip that protects the contact area against dust and dirt. With 140 mm shaft, 155 mm housing bore and a height of 9.00/12.00 mm, it is a size intended for medium-sized equipment operating with permanent lubrication.

This DBH 1306/85 seal has a shaft diameter of 140 mm, a housing bore diameter of 155 mm and an overall height of 9.00/12.00 mm. The A 429 design corresponds to a seal with a double lip: the main lip retains the lubricant and the secondary lip, facing outward, blocks the ingress of contaminants. The designation 1306/85 identifies the size within the DBH line and is used to order the exact replacement.

It is used in gear reducers, centrifugal pumps, electric motors, rollers and transmission equipment where the shaft rotates on a bearing and the oil must be contained. It also appears in machines in the food, chemical and process industries, provided the lip material is compatible with the fluid and the working temperature. It is a wear part: it should be checked at every scheduled shutdown.

To install it, verify that the shaft has no burrs or deep marks on the sealing surface and that the housing is clean and free of deformation. Lubricate the lip before inserting it and fit the seal with a support tube that presses on the outer diameter, never on the lip. If the shaft shows wear, consider a repair sleeve before forcing the same part.

If you need an equivalent, send us part number 1306/85 along with the shaft, housing bore and height dimensions, the type of lubricant and the service temperature. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also advise you if the A 429 design is not the right one for your application.
