The DBH 9893 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —73 mm shaft, 89.50 mm housing bore and a height of 8.00/15.50 mm— make it suitable for gearboxes, pumps and transmission equipment where axial space is limited. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the code 9893. According to the data sheet, it corresponds to a shaft of 73 mm diameter, a housing bore of 89.50 mm and a total height of 8.00/15.50 mm. The A 339 design defines the geometry of the lip and the outer body. It is a replacement part intended to be press-fitted into the housing bore and seal against the shaft, with the aim of containing oil or grease and preventing the ingress of dust, water or particles.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, transmission shafts and industrial equipment in general. In all cases, the seal works as a dynamic barrier: it rotates with the housing bore and its lip runs against the lubricated shaft. That is why it is essential that the shaft has a ground surface free of grooves, and that the housing bore has the right diameter and depth for the 8.00/15.50 mm height.

To correctly select this seal, check that the shaft diameter is exactly 73 mm and that the housing bore measures 89.50 mm. The height of 8.00/15.50 mm indicates that the seal can be installed in housing bores with different depths within that range. During installation, lubricate the lip, avoid striking it and make sure the spring is on the fluid side to be retained. If the shaft is worn, consider a seal with an auxiliary lip.

If you need an equivalent, the most practical thing is to send us the code 9893 or the current dimensions: shaft diameter, housing bore diameter and height. With that data we can look for alternatives within the same DBH brand or from other brands we carry. We can also guide you if the A 339 design does not match the original seal and a variant with different characteristics is needed.
