The DBH 9337 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With 17 mm shaft diameter, 47 mm housing and 8 mm height, and Lx design, it is press-fitted into the housing and works on the shaft with a flexible lip. It is a wear part: when it starts to leak, replacement with the same size prevents leaks and contamination in gearboxes, pumps and motors.

The DBH 9337 is a single-lip seal with metal case and elastomer, identified by its designation 9337. Its dimensions are 17.00 mm shaft diameter (d), 47.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to the lip geometry and the type of case; to confirm the elastomer material and the spring, it is advisable to check the manufacturer's data sheet. It is a small size, one of those used on small-section shafts.

It is found in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment where there is a shaft rotating inside a lubricated housing. Also in applications with dust or water, where the seal prevents the contaminant from entering the bearing. Being a wear part, periodic replacement with the same size is what maintains the sealing of the assembly throughout the equipment's service life.

To select it, verify that the shaft and housing diameters match the values in the data sheet: 17 mm and 47 mm respectively. Check the condition of the shaft surface, that it has no burrs or wear, and lubricate the lip before mounting. The seal is inserted perpendicular to the shaft, without hitting the lip, with a tube or shim that rests on the case. If the housing has a shoulder or the shaft is damaged, the seal will not seal even if the size is correct.

To quote the 9337, send us the code and the shaft, housing and height dimensions. With that data we search for the equivalent in the same series or in another brand, respecting the Lx design.
