The DBH 9956 radial shaft seal is a lip seal that closes off the passage of lubricant and blocks the entry of dust, water or particles in equipment with a rotating shaft. Its Lx design combines a sealing lip with a metal body that press-fits into the housing. It is used in gearboxes, pumps, electric motors and similar mechanisms where oil or grease must be retained between a 15 mm shaft and a 23 mm housing.

This seal has the dimensions 15.00 mm shaft diameter, 23.00 mm housing diameter and 5.00 mm height. The Lx design corresponds to a single-lip seal with a metal case and sealing lip, suitable for rotating shafts with lubrication. The 9956 nomenclature identifies the size in the DBH catalogue, and the part number is used to order the exact replacement without depending on the brand of the original equipment.

It is used in gearboxes, centrifugal pumps, electric motors, compressors and transmission shafts where a 15 mm shaft must be sealed against a 23 mm housing. It is also used in washing equipment, water pumps and mechanisms exposed to dust or splashes. It is a wear component: when lubricant loss or dirt ingress appears, it should be replaced before it damages nearby bearings or bushings.

To install it, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and apply force on the metal edge, never on the lip. If the shaft has play or roughness, the seal will not seal even if the size is correct. The 5 mm height must match the housing depth so that it seats fully.

If you can't find part number 9956, we can look for an equivalent from another brand or a nearby size within the same series. For that we need you to send us the shaft diameter, housing diameter and height, as well as the type of fluid and the operating temperature. With that data we review compatible alternatives and confirm which one fits without modifying the housing.
