The DBH 1306/85 is a radial shaft seal that prevents lubricant from escaping along a rotating shaft. Its A 429 configuration includes both a sealing lip and an additional dust lip to keep contaminants out. Sized for a 140 mm shaft, a 155 mm housing bore, and a height of 9.00/12.00 mm, it fits medium-sized equipment that runs with continuous lubrication.

This seal's dimensions are shaft 140 mm, housing bore 155 mm, and overall height 9.00/12.00 mm. The A 429 design means a double-lip seal: the primary lip holds the lubricant in, while the secondary lip, facing outward, blocks dirt and dust. The code 1306/85 indicates the size within the DBH line and is the number to use when ordering a replacement.

Typical applications include gear reducers, centrifugal pumps, electric motors, rollers, and transmission equipment where a shaft turns on a bearing and oil must be contained. It also appears in food, chemical, and process industry machines when the lip material suits the fluid and operating temperature. As a wear part, it should be inspected during every scheduled shutdown.

During installation, check that the shaft surface is free of burrs or deep grooves and that the housing is clean and undistorted. Lubricate the lip before fitting, and use a support tube that presses on the outer diameter—never on the lip. If the shaft is worn, a repair sleeve may be needed instead of forcing the same seal.

For an equivalent, provide part number 1306/85 along with the shaft, housing bore, and height dimensions, plus the lubricant type and service temperature. With that information, we can search for an alternative within the DBH line or from other brands we carry. We can also advise whether the A 429 design is appropriate for your application.
