The DBH 9343 seal is a radial shaft seal with a 20 mm shaft diameter, 50 mm housing diameter and 7 mm height, with Lx design. It is used to retain lubricant and exclude contaminants on rotating shafts, inside gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your application.

The DBH 9343 is a radial shaft seal with the following dimensions: shaft diameter 20 mm, housing diameter 50 mm and height 7.00 mm. Its Lx design corresponds to a single sealing lip with a spring, intended for lubricated rotating shafts. The elastomeric lip rests on the shaft and the spring maintains contact pressure; the outer body is metal for a firm fit in the housing. It is a standard replacement part for 20 mm shafts with a 50 mm housing.

It is used in equipment where oil or grease must be retained and dust, water or particles kept out. It is common in gearboxes, centrifugal pumps, electric motors, compressors, mixers and transmission shafts. It also appears in machine tools, washing equipment and conveyor systems. Whenever there is a rotating shaft passing through a housing and two environments need to be separated, a seal like the 9343 performs that function.

To install it, verify that the shaft has the right dimensions and surface finish, with no burrs or marks that could damage the lip. Lubricate the lip before inserting it and use an installation tube that presses on the outer diameter, never on the lip. The seal must sit perpendicular to the shaft. If the shaft shows wear, consider a nearby size or a seal with the lip in another position. Selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a different size, send us part number 9343 or the dimensions of your current seal: shaft diameter, housing diameter and height.

The more data you give us, the more precise the proposal will be.
