Polyacrylate radial shaft seals

421 DBH radial shaft seals in polyacrylate. DBH puts the material at the end of the code: the polyacrylate ones end in Pol. Send us the code or the three dimensions (shaft, housing and width) and we will quote it.

Polyacrylate (ACM) withstands mineral oils and lubricants with additives at higher temperatures than nitrile, which is why it is used in gearboxes, transmissions and reducers. It does not cope well with water or very low temperatures.

The material does not change the size: a polyacrylate seal and a nitrile seal with the same dimensions fit the same housing. What changes is what the lip withstands: temperature, lubricant and the surrounding medium. If you do not know your seal material, send us a photo and tell us about the equipment (which lubricant, at what temperature and how fast the shaft turns) and we will help you choose.

Only have the size? The seals-by-size index lists every size in the catalogue, with its codes from all brands.
