This item is a DBH 9398 radial shaft seal, identified by its designation 9398 and its standard dimensions: 30.00 mm shaft diameter (d), 56.00 mm housing diameter (D) and 8.00 mm height (h). Its Lx design corresponds to a seal with a single sealing lip and a reinforced outer body, intended for press fitting into a cylindrical housing. DBH is a brand that MR carries, which technically backs the product.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, its function is twofold: to prevent oil or grease leaks and to block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a critical part in the preventive maintenance of industrial machinery.

To correctly select and install the 9398 seal, verify that the shaft diameter is within the recommended tolerance and that the contact surface has suitable roughness. The housing must be clean, free of burrs and with the entry chamfer in good condition. Lubricate the lip before installation and avoid striking it during fitting. If the shaft shows wear, consider a repair sleeve or an alternative size.

If you need an equivalent seal, the most practical approach is to send us the full part number, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for an alternative within the same brand or another line we carry. We can also advise you if the original seal has a special design, such as a double lip or a dust lip.
