The DBH 9227/85 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With 30.00 mm shaft, 42.00 mm housing and 8.50 mm height, and A 016 design, it is used to keep lubricant inside the assembly and block the entry of dust, water or particles. It is a wear part: when leakage appears, it is replaced.

This oil seal is identified by its designation 9227/85 and runs on a 30.00 mm shaft (d), inside a 42.00 mm housing (D), with a total height of 8.50 mm (h). The A 016 design corresponds to a single-lip seal with a metal case and an elastomeric sealing lip, backed by a spring that maintains contact pressure against the shaft. That combination of dimensions and geometry defines the seat: if the shaft or housing do not match, the seal will not seal.

Typical applications are gearboxes, pumps, electric motors, rollers and transmission equipment where there is a rotating shaft and a lubricant that must be confined. It also appears in agricultural machinery, conveyors and process equipment, provided the shaft has the proper hardness and finish. In all those cases it serves the same function: retain the oil or grease and prevent contaminants from entering the bearing or gear.

To install it, check that the shaft has no burrs or wear marks in the lip area and that the housing is clean and free of deformation. Lubricate the lip before seating it and place the seal perpendicular to the shaft, without striking it from the side. If the shaft has a step or groove, the lip must rest on a continuous surface. Selection is defined by the d, D and h dimensions and by the design; do not replace it with one of a different height without checking the seat.

If you need an equivalent, send us the code 9227/85 along with the shaft, housing and height dimensions, and a photo or sketch of the housing. With that data we look for the alternative in the same category or in another brand, respecting the design and lip type. If the original seal is not available, a compatible standard size can be evaluated, always confirming the fit before installation.
