The DBH 5130Sil radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 30 mm shaft, 52 mm housing and 10 mm height place it in medium-sized transmission and rotation equipment. It is a wear part: when the lip hardens or becomes marked, it starts losing oil and should be replaced before the bearing fails.

This item is a seal from the DBH line, identified as 5130Sil. Its published attributes are: shaft diameter 30 mm, housing diameter 52 mm and height 10 mm. The Lx design corresponds to a single lip seal with spring, intended for rotating shafts with lubrication. The code nomenclature summarizes those three dimensions: 30 shaft, 52 housing and 10 height. Before installing, verify that the housing is ground and that the shaft shows no wear on the contact track.

It is used in gearboxes, centrifugal pumps, electric motors, mixers and belt or chain transmission equipment. It also appears on fan shafts, compressors and machine tools where oil must be separated from the environment. In all those cases it performs the same function: keep lubricant inside and contamination outside. If the equipment operates with a lot of dust or frequent washing, the seal is the first barrier and its condition defines the service life of the bearing.

To select a seal, the dimension alone is not enough: the peripheral speed of the shaft, the working temperature and the type of lubricant matter. A poorly lubricated lip crystallizes and loses elasticity; a shaft with longitudinal scratches wears the lip in a few hours. During installation, lubricate the lip with the same grease or oil as the equipment, insert the seal perpendicular to the shaft and tap only on the outer ring, never on the lip. If the housing has a burr, correct it before seating the part.

If you need a nearby size or an equivalent from another brand, send us the code engraved on the old seal, the shaft, housing and height dimensions, and a photo of the assembly. With that data we search the DBH line or the alternatives we carry. We can also advise you if the Lx design is not suitable for your application and a different lip type or a different metal case is better. The more precise the information, the faster we reach the correct part.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If you already have the code 5130Sil, send it via WhatsApp and we will provide the quote.
