The DBH 9953Pol radial shaft seal is a lip seal designed to block the passage of oil or grease in equipment with a rotating shaft. Its dimensions of 121.10 mm shaft diameter, 160.20 mm housing bore and 35.00 mm height place it in medium-to-large assemblies, where axial space is limited and a reliable barrier against leaks and contamination is needed. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains dynamic contact.

This item is an oil seal from the DBH line, identified by part number 9953Pol. Its standardized dimensions are 121.10 mm shaft diameter (d), 160.20 mm housing bore diameter (D) and 35.00 mm height (h). The A 354 design corresponds to a single-lip configuration with spring, intended to retain lubricant and exclude dust in continuous rotation applications.

Typical applications for an oil seal of this size appear in gearboxes, centrifugal pumps, conveyor rollers and power transmission equipment. In all cases it serves to separate the lubricated interior from the external environment, preventing oil loss and the ingress of particles that accelerate wear on bearings and gears. It is also used on fan and mixer shafts where the seal must withstand moderate peripheral speeds.

For mounting, check that the housing and shaft have no burrs or deep scratches, and lubricate the lip before inserting it to avoid damage at start-up. Seal selection depends on rotational speed, service temperature and the type of fluid to be retained. If the equipment operates with high vibration or misalignment, consider a design with greater lip rigidity or a reinforced metal case.

If you need a nearby size or an equivalent from another brand, send us part number 9953Pol along with the shaft, housing and height dimensions. With that data we can look for an alternative that performs the same function without modifying the assembly. We can also advise you if the original seal has a special design that should be replaced with a more resistant one.
