The DBH 5121Sil radial shaft seal is a lip seal that mounts in a component housing and seals against the rotating shaft to retain lubricant and stop dust, water or particles from entering. With a 15 mm shaft, 35 mm housing and 10 mm height, and Lx design, it is a small size in frequent use in industrial and automotive equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH radial shaft seal with the designation 5121Sil, with the following dimensions: shaft diameter 15 mm, housing diameter 35 mm and height 10 mm. The stated design is Lx, which corresponds to the construction configuration of the lip and the metal body. The code 5121Sil identifies the size and type within the DBH line, so it is advisable to verify that it matches the seal you are replacing before ordering it.

Seals of this size are used in small gearboxes, pumps, electric motors, compressors, machine tools and transmission equipment. They also appear on wheel shafts, final drives and components of automotive and agricultural machinery. In all cases they perform the same function: keeping oil or grease inside the assembly and preventing contaminants from entering that accelerate wear on bearings and gears.

To select a seal correctly, the three dimensions must be respected: shaft diameter, housing diameter and height. Also take into account the lip type, the material and the direction of rotation, because not all designs work for the same speed or the same fluid. If the shaft is scored or the housing has play, the new seal may not seal even if the size is correct. In that case it is advisable to evaluate a wear sleeve or repair the seat.

If you cannot find the code 5121Sil or you need a nearby size, send us the dimensions of the old seal — shaft, housing and height — and a photo of the part. With that we look for the equivalent in DBH or another brand of the same size and design. We can also check whether there is an alternative with a different lip or material for your application. The idea is that the equipment does not stop because of a seal that is available in another size.
