The DBH 1399 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil, grease or contaminants in gearboxes, pumps and motors. Its A 444 design combines a sealing lip with a metal body that is press-fitted into the housing. With dimensions of 29 mm shaft, 39.90 mm housing and a height of 10.00/15.30 mm, it is a replacement part for equipment where lubricant must stay inside and dirt outside.

This item is a DBH 1399 radial shaft seal, identified by the code 1399. Its dimensions are shaft (d) 29 mm, housing (D) 39.90 mm and height (h) 10.00/15.30 mm. The A 444 design defines the geometry of the lip and the outer body. The double height indicates that the seal has a stepped profile or a section that can be mounted in housings with different depths within that range. It is a rotary sealing part, not a structural component.

It is used in equipment with rotating shafts where lubricant must be retained and dust, water or chips blocked. It appears in gearboxes, reducers, centrifugal pumps, electric motors, mixers and chain or belt drives. Also in old or imported machines where obtaining the original seal by manufacturer code is difficult and an equivalent size is sought.

To select the seal correctly, verify that the shaft and housing diameters match the values in the data sheet. The lip must rest on a shaft surface free of splines, rust and with adequate hardness; if the shaft is worn, consider a seal with an offset lip or a repair sleeve. The height 10.00/15.30 mm allows it to adapt to housings with a shoulder. Lubricate the lip before mounting and avoid striking it during installation.

To quote the code 1399, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we look for the equivalent in DBH or another brand we sell. We can also indicate whether the A 444 design is interchangeable with another profile. The more complete the information, the faster we can provide the alternative.
