The DBH 1207/85 is a radial shaft seal built to keep oil or grease inside crankcases, gearboxes and other rotating assemblies. Its A 392 design pairs a main sealing lip with a secondary dust lip, so lubricant stays in while dirt is kept out. The seal fits a 22 mm shaft in a 47 mm housing bore and has a height of 5.50/10.00 mm, which makes it a frequent replacement item on maintenance schedules.

The part carries the DBH brand, reference 1207/85 and design A 392. Nominal dimensions read as follows: shaft 22 mm, housing 47 mm, height 5.50/10.00 mm. In the A 392 layout, two lips work together — one retains the lubricant, the other blocks contaminants from reaching the sealing edge. The height is stepped rather than flat: the dust lip stands proud of the main body, so the 5.50/10.00 mm figure reflects both the body and the protruding lip. That step is worth measuring before installation to confirm the housing has room for it.

Gearboxes, electric motors, pumps, mixers and transmission units are the usual homes for a seal like this, wherever a turning shaft has to be closed off against oil or grease loss. In dusty or particle-laden surroundings, the second lip of design A 392 adds a barrier that a single-lip seal does not provide. Treat it as a wear part: dripping lubricant, noticeable shaft play or a scheduled overhaul are all signals to replace it.

Sizing a radial shaft seal comes down to three checks — shaft diameter, housing bore and the height the cavity can accept. Here those values are 22 mm, 47 mm and 5.50/10.00 mm. The shaft surface itself matters just as much: it should be ground, free of grooves and hard enough not to chew the lip. When fitting, coat the lip with the same oil or grease the equipment runs on, press the seal in squarely and never hammer it directly. Any burrs in the housing should be dressed before the part goes in.

Looking for an equivalent? Send the reference 1207/85 together with the shaft, housing and height measurements. With that information we can search alternatives in the DBH range or in other brands we supply, keeping to the same dimensions and design type. We can also tell you whether the cavity allows a seal with or without a dust lip, or whether a different material suits the fluid and operating temperature better.
