The DBH 6862 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 40 mm shaft, 52 mm housing and 7.50 mm height place it in medium-sized transmission and rotating equipment. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

The DBH 6862 is a radial shaft seal with an Lx design, with a 40 mm shaft, 52 mm housing and 7.50 mm height. The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts where oil or grease sealing is a priority. It is made of elastomer resistant to mineral oils and moderate temperature, and its metal structure gives it rigidity to maintain the fit in the housing. It is a wear part: when the lip hardens or gets marked, it starts to leak and must be replaced.

These seals appear in gearboxes, electric motors, centrifugal pumps, compressors, fan shafts and belt- or chain-driven transmission equipment. They are also used in agricultural machinery, conveyors and process equipment where the lubricated side must be separated from the environment. In all these cases the seal serves two functions: preventing lubricant from escaping and preventing contaminants from entering that accelerate the wear of bearings and gears.

To install it, check that the shaft is clean, free of burrs and with the proper roughness; a scratched shaft or one worn in the lip area means the seal will not seal even if it is new. Lubricate the lip before fitting it, insert it perpendicular to the shaft and use a tube or shim that pushes on the outer ring, never on the lip. If the housing has burrs or the seal goes in crooked, the seal fails. When selecting, in addition to the dimensions, take into account the type of fluid, the working temperature and the shaft speed.

If the 6862 is not the exact size you need, an equivalent can be found in other brands or a neighboring size within the same series. For that, it is best to send the old part number, the shaft, housing and height dimensions, and a photo or sample of the seal. With that data, the lip design, material and temperature range are compared to offer you an alternative that performs the same function without modifying the housing.

MR Accesorios Industriales carries the DBH brand and has more than 80 years of experience in bearings, seals and power transmission. If you already have the 6862 part number or the dimensions, send it by WhatsApp and we will quote you. We can also help you identify the seal if you only have the sample or hand-taken measurements.
