The DBH 9970 radial shaft seal is a lip seal for rotating shafts that is mounted in the housing of a casing or box. Its function is to keep the lubricant inside the assembly and stop dust, water or particles from entering, protecting bearings, bushings and gears. It is used in pumps, electric motors, gearboxes and power transmission equipment, where the shaft rotates continuously and a reliable barrier is needed. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a seal from the DBH line, identified by part number 9970 and design A 359. Its dimensions are 57 mm shaft diameter, 79 mm housing diameter and a height of 9.00/13.50 mm, meaning the sealing lip has a different extension than the metal body. That double height allows the seal to sit in chambers with a recess and keep the lip against the shaft with the right interference.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, mixers and power transmission equipment. In all those cases the seal closes the passage of oil or grease to the outside and prevents the contaminated environment from reaching the bearing. It is also used as a secondary seal in split plummer block housings and in machines where the shaft is subject to continuous rotation.

To select a seal properly, check the shaft diameter, the housing diameter and the available height. Design A 359 defines the geometry of the lip and the body, so it is advisable to compare that shape with the original seal before replacing it. Installation requires cleaning the shaft, lubricating the lip and seating it without striking it, using a tube or spacer that pushes on the outer ring and not on the lip.

If part number 9970 does not appear on your list or you need a nearby size, send us the shaft diameter, the housing diameter and the height you have. With those data we look for the equivalent seal within the DBH line or another brand we carry. We can also advise you if design A 359 does not match the one you need and another lip or body variant has to be evaluated.
