The DBH 5127Sil is a radial shaft seal built for a 42 mm shaft and a 72 mm housing, with a 10 mm height. It keeps lubricant in and contaminants out where a rotating shaft passes through a housing, and it is a standard wear item on gearboxes, pumps and motors. The Lz design uses a sealing lip backed by a spring to hold contact against the shaft.

The code breaks down into the 42 x 72 x 10 mm size and the 5127Sil construction within the DBH line. An elastomer compatible with mineral oils and greases forms the sealing element, while a metal case provides the rigidity needed for press fitting. The Lz designation indicates a lip seal with a spring that maintains pressure on the shaft.

You will find this seal in gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools, as well as in agricultural and general industrial equipment where oil or grease must stay in and bearings must stay protected. Any assembly with a 42 mm shaft and a 72 mm bore is a candidate for this size.

Before installation, check the shaft for burrs or wear and make sure the housing is clean and free of dents. Coat the lip with the same lubricant used in the equipment, then seat the seal with a tube or press that pushes on the case, not the lip. A deep groove on the shaft may call for a seal with an offset lip. Speed, temperature and the fluid involved all affect selection.

If you are matching a replacement, send the 5127Sil code or the shaft, housing and height dimensions. We can also review other qualities or designs when the working environment is demanding.
