The DBH 6444 radial shaft seal is a lip seal mounted in a component housing to retain lubricant and block the ingress of dust, water or particles. With dimensions of 54 mm shaft, 79.4 mm housing and 19.05 mm height, and A 111 design, it is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales distributes this official brand and advises you to choose the correct seal for your application.

This item is a DBH 6444 radial shaft seal, identified by the 6444 designation and the A 111 design. Its dimensions are 54 mm shaft diameter (d), 79.4 mm housing diameter (D) and 19.05 mm height (h). The A 111 design corresponds to a single lip configuration with spring, intended for rotating shafts with lubrication. The lip elastomer and the metal case work together to maintain sealing under normal operating conditions.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, drive shafts and process equipment. In all cases it fulfills the function of confining oil or grease inside the assembly and preventing contaminants from entering from outside. It is a wear part that should be replaced when lubricant loss appears or when the lip shows hardening, cuts or deformation.

For correct installation, verify that the shaft and housing diameters match the indicated dimensions, that the shaft surface is clean and free of burrs, and that the seal is inserted perpendicular to the shaft without striking it. Lubricate the lip before assembly. When selecting a replacement, take into account the rotation speed, working temperature and type of fluid, because the lip material and spring depend on these factors.

If you need an adjacent size or an equivalent, the most practical approach is to send us the 6444 code or the current dimensions of your seal: shaft diameter, housing diameter and height. With that data we can look for an alternative within the same family or suggest a compatible design. We can also advise you if the mounting space allows height or lip type variants.
