The DBH 5169 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 41.28 mm shaft, 73.02 mm housing and 11.90 mm height correspond to a specific application, so it is advisable to verify the cavity before replacing it. MR Accesorios Industriales sells this brand and advises you so the seal works with the correct interference and concentricity.

This item is a seal with Lz design, with the dimensions shown on its product page: shaft diameter 41.28 mm, housing diameter 73.02 mm and height 11.90 mm. The Lz design defines the geometry of the lip and the metal body, and it is the data that must be respected when looking for an equivalent part. It is not a round nominal size, but a specific application dimension, so the replacement must match all three values so that the lip seats where it should.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, transmission shafts and equipment with bearings lubricated with oil or grease. Their function is twofold: to prevent leaks to the outside and to stop the entry of contaminants that accelerate the wear of bearings and gears. In the same equipment they often coexist with housings, bushings and bearings, so the selection of the seal conditions the service life of the assembly.

To install it, clean the housing and the shaft, check that there are no burrs or rotation marks and lubricate the lip before inserting it. The seal must enter perpendicular, without blows that deform the metal body. Also check the condition of the shaft: a scratched or worn surface means the lip will not seal even if the dimension is correct. If the equipment works with a lot of vibration or temperature, take that into account when choosing the lip material.

If you need an equivalent, send us the code 5169 together with the shaft, housing and height dimensions, and a photo or sketch of the housing. With that data we can compare against other alternatives in the same family and confirm whether there is a compatible option. It also helps if you indicate the equipment where it is mounted and the lubricant it uses, because that helps guide the selection.
