The DBH 5745 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and water in equipment with a rotating shaft. It is press-fitted into the housing and its flexible lip runs on the shaft. It is a wear part: when lubricant loss or contaminant ingress appears, it is replaced. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a DBH radial shaft seal identified with the code 5745. Its dimensions are: shaft diameter 85.73 mm, housing diameter 111.15 mm and height 15.87 mm. The design is Lx, with a sealing lip and metal body for press fitting. The elastomer and the internal spring are not detailed in the record, so they are confirmed against the manufacturer's data sheet at the time of quoting. The designation 5745 corresponds to that exact combination of dimensions.

It is used in gearboxes, pumps, electric motors, mixers and transmission equipment where the shaft rotates inside a housing and there is lubricant to retain. It also appears in agricultural machinery, conveyors and process equipment. When the seal fails, oil loss is visible, the lubricant becomes contaminated or the lip wears. In those cases it is advisable to also check the condition of the shaft and the housing, because a scratched surface accelerates the wear of the new seal.

To select the seal, measure the shaft diameter in the contact area, the inner diameter of the housing and the available depth. The lip should have a slight interference fit on the shaft, without forcing it. Before installing, lubricate the lip with the same grease or oil used in the equipment, check that the shaft has no burrs and place the seal perpendicular to the shaft. If the housing is damaged, consider repairing it or using an alternative size.

If you cannot find the code 5745 or you need a nearby size, send us the shaft, housing and height dimensions, plus a photo of the old seal if possible. With that data we look for the equivalent in DBH or another brand we carry. We can also verify whether the Lx design is right for your application or whether another type of lip is better. The idea is that you do not buy blindly: first we confirm that the part fits and seals properly.
