The DBH 9866/85 is a radial shaft lip seal built to keep lubricant in and contaminants out of rotating equipment. Its A 322 design and compact 6.30 mm profile suit assemblies where axial room is tight but dependable sealing is still required.
Reading the specification is straightforward: the seal fits a 19.05 mm shaft, presses into a 34.60 mm housing bore, and measures 6.30 mm in height. The A 322 designation describes a single-lip radial shaft seal with a spring. The 9866/85 code is the catalog reference you will use to identify the series and size.
Because it seals against both the shaft and the housing, this component helps prevent oil or grease from escaping and blocks dust or water from entering. Its low profile makes it a common choice for gearboxes, pumps, electric motors, speed reducers, and other power transmission assemblies. Shafts near 19 mm — such as those on agricultural machinery, conveying systems, and production lines — are typical hosts for this size.
Correct installation protects performance. Confirm the shaft and bore are clean and free of burrs or scratches, then lubricate the lip with the same oil or grease used in the equipment. Press on the outer diameter with a proper installation tool; never drive on the lip. The 6.30 mm height defines the axial space the seal occupies. When choosing a seal, account for shaft speed, operating temperature, and the fluid being retained. The A 322 design is intended for standard applications at moderate pressures.
If you need a replacement or an alternative, the quickest route is to send the 9866/85 code or your shaft and housing dimensions. We can check options within the same DBH brand or other lines we supply, and we can advise if the mounting space calls for a different dimension. Matching the original dimensions is the safest way to restore proper sealing.
