The DBH 9243/85 is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a stationary housing. You will find it in gearboxes, pumps, motors and reducer boxes. DBH is one of the seal brands we supply, and this part number gives you a standard size for replacement or new assembly work.

The designation breaks down to shaft 30 mm, housing 50 mm, height 7.00 mm. The A 016 design is a single lip with spring for lubricated rotating shafts. In the 9243/85 code, the leading digits refer to the shaft diameter and the rest to the housing bore. The 7 mm section keeps the seal low-profile, so it fits where a taller seal will not.

You will typically see this seal in gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment, as well as in agricultural machinery and conveyors. Its job is to hold oil or grease inside the assembly and block dust, water and particles that would otherwise reach the bearings. In every case, the seal runs against a rotating shaft and sits in a fixed housing.

Before installation, inspect the shaft for burrs or wear and make sure the housing is clean and free of dents. Coat the lip with the same oil or grease used in the equipment, then press the seal in with a tube or press that contacts the metal case, not the lip. If the shaft shows a deep groove, an offset-lip seal is worth considering. Speed, temperature and lubricant type all affect the choice, so confirm those details before ordering.

If you need an alternative, we can search the DBH line for an equivalent. Send the shaft, housing and height dimensions, the design type if you have it, plus a photo or the old part number. We can also suggest an option from another brand we carry. The more information you provide, the faster we can confirm a fit that works without machining the housing.
