A rotating shaft needs a barrier that holds lubricant in and keeps dust, water and particles out. The DBH 5409 radial shaft seal does that job: it is a lip seal with a spring, sized for a 31.75 mm shaft, a 44.50 mm housing bore and a 9.52 mm width, in the Lx design. MR supplies this brand and helps maintenance and purchasing teams confirm the right seal before they order.
Reading the code is the fastest way to confirm the part. The designation 5409 identifies this DBH seal, and the three figures that matter on the drawing are shaft 31.75 mm, housing 44.50 mm and width 9.52 mm. Those are the values to compare against your shaft and bore measurements. The Lx design means the seal combines a sealing lip with a spring, which is the usual choice for lubricated rotating shafts.
Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. The job is always the same: keep the lubricant where it belongs and stop contaminants from reaching the bearing. Where there is vibration or moderate temperature, a spring-loaded lip seal such as the 5409 is a common fit.
Installation decides how long the seal lasts. Confirm the shaft measures 31.75 mm and the bore 44.50 mm, with at least 9.52 mm of depth to seat the seal. The shaft surface should be polished and free of burrs, the lip gets a light film of lubricant before it goes in, and the seal should be pressed squarely without impact. If the equipment runs at high speed or under high pressure, ask us about an alternative design.
If you are cross-referencing, send the code 5409 or simply your shaft and housing dimensions. We can check equivalents from other brands or suggest the next size up or down, and we can advise on lip type, material and spring based on the fluid and the working temperature.
