The DBH 1399 is a radial shaft seal designed to keep lubricant in and contaminants out of rotating equipment. Its A 444 profile features a sealing lip and a metal outer case that presses into the housing. With a 29 mm shaft, 39.90 mm housing bore and a height of 10.00/15.30 mm, it serves as a replacement in gearboxes, pumps and motors where oil or grease must be retained.

The DBH 1399 is identified by code 1399 and built to the A 444 design, which sets the lip and body geometry. Key dimensions are shaft 29 mm, housing 39.90 mm and height 10.00/15.30 mm. The dual height figure indicates a stepped profile or a section that fits housings of varying depths within that range. This is a rotary sealing element, not a load-bearing part.

Typical installations include gearboxes, speed reducers, centrifugal pumps, electric motors, mixers and chain or belt drives. It also suits older or imported machines where finding the original seal by manufacturer code is impractical and a size match is the goal.

For proper selection, confirm that shaft and housing diameters align with the data sheet. The lip should run on a shaft surface that is smooth, free of splines and rust, and sufficiently hard. If the shaft is worn, a seal with an offset lip or a repair sleeve may be needed. The 10.00/15.30 mm height allows adaptation to housings with a shoulder. Lubricate the lip before installation and avoid impact during fitting.

To request a quote for code 1399, provide the old seal's shaft diameter, housing diameter and height. We will match it to an equivalent in DBH or another brand we carry and can advise whether the A 444 design interchanges with other profiles. Complete information speeds up the alternative.
