The DBH 5442Sil is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a housing. With a 150 mm shaft, 180 mm housing and 13 mm height, it fits medium to large equipment such as gearboxes, pumps and electric motors.

This seal carries the Lx designation, meaning a single lip with a spring for shafts under continuous rotation and permanent oil lubrication. The code 5442Sil identifies the part within the DBH line, so you can order it by number without confusion. Before installation, inspect the shaft for burrs or scratches and make sure the housing bore is clean and round.

Sizes in this range appear in gearboxes, speed reducers, centrifugal pumps, large motors, mixers and transmission drives. In each case the seal does two jobs: it holds oil or grease inside the assembly and it blocks dust, water and particles from entering. On equipment that runs hot or vibrates, check the lip and spring at every scheduled shutdown.

To select a radial shaft seal correctly, match all three dimensions: shaft, housing and height. Speed, temperature and lubricant type also affect the choice. The Lx design suits continuously rotating shafts with oil lubrication. When mounting, coat the lip with lubricant, press the seal in squarely and apply force to the outer ring only, never to the lip.

To quote code 5442Sil, send the shaft, housing and height measurements. A photo of the old seal or the housing drawing also works. We will review options in the DBH line and from other brands we supply. Keep in mind that shaft and housing tolerances matter as much as the nominal dimensions.
