A radial shaft seal like the DBH 5031Pol keeps lubricant where it belongs and keeps contaminants out. It seats in the housing and its lip runs against the rotating shaft, so it is the part that stands between clean oil and a dirty environment. With a 28.00 mm shaft, a 40.00 mm housing bore and a 7.00 mm height, it fits compact assemblies where there is little room along the shaft. MR Industrial Accessories supplies it as part of its seals and oil seals range for maintenance and replacement work.
Reading the code tells you most of what you need. The dimensions are built into the designation: shaft 28.00 mm, housing 40.00 mm, height 7.00 mm. The Lx configuration is a single lip on a metal body, made for rotating shafts that run with oil or grease. The 5031Pol number identifies the exact item in the DBH line, so a replacement can be ordered without confusion.
Typical locations are gearboxes, pumps, electric motors, transmission shafts and process equipment where lubricant has to stay separated from the surroundings. Machine tools, conveyors and washing equipment also use this type of seal to shield bearings from water and dust. Treat it as a wear item and inspect it whenever you see lubricant loss, hear bearing noise or find dirt building up near the shaft.
Selection starts with three measurements: shaft, housing bore and height must match the seal being replaced. Look at the shaft surface as well. A scratched or burred track will destroy a new lip quickly. On installation, coat the lip with the same oil or grease the equipment uses, press the seal in square to the shaft and keep sharp tools away from the lip. Remove any burrs in the housing first.
For a quote on part number 5031Pol, send the dimensions of the old seal (shaft, housing, height) plus a photo. With that we can match it in the DBH line or in another brand we carry. If the Lx design does not suit your application, we can point you toward a different lip style or material.

Frequently asked questions
- How do I know if the Lx design is what my equipment needs?
- Lx means a single-lip seal on a metal body for lubricated rotating shafts. If the seal you are removing has one lip and a metal case, this is the direct replacement. If it has a second lip, an exposed spring or another layout, send a photo and we will check it.
- Can I order a size other than the published one?
- Yes. If your shaft, housing bore or height differs, message us with the dimensions and the part number if you have it. We look for the equivalent in the DBH line or in the other brands we supply.
- What are the dimensions of the DBH 5031Pol oil seal?
- Shaft 28.00 mm, housing 40.00 mm, height 7.00 mm. These come from the designation, and they are the figures to compare against the old seal before ordering.
