The DBH 6831Pist oil seal is a radial shaft seal from the DBH brand, designed to retain lubricant and block contaminants from entering rotating shafts. It is used in gearboxes, pumps, electric motors and transmission equipment where the seal runs on a shaft and inside a housing. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application. If you need to confirm dimensions or evaluate an alternative, send us the part number via WhatsApp and we will review it with you.

This item is a DBH radial shaft seal identified with part number 6831Pist. Seals of this type combine an elastomeric lip, a metal case and a spring that maintains contact on the shaft. The commercial designation does not include dimensions, so the inner diameter, outer diameter and width are confirmed against the manufacturer's data sheet or by direct measurement of the part. Do not publish dimensions that are not verified: it is better to request a quote with the exact part number and validate the geometry before installation.

Typical applications of a radial shaft seal such as the 6831Pist appear in equipment with rotating shafts: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and process machinery. In all these cases the seal serves two functions: retaining oil or grease inside the assembly and preventing dust, water or particles from entering the bearing or bushing. The choice of lip material and spring depends on temperature, peripheral speed and the type of lubricant.

To install a radial shaft seal, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before inserting it and use an installation tube that presses on the outer diameter, never on the lip. If the shaft shows a marked wear groove, consider a seal with an offset lip. Proper alignment between shaft and housing prevents premature leaks and extends seal life.

If you need an equivalent or a different size than the 6831Pist, send us the part number, a photo of the part and the dimensions taken with a caliper. With that data we look for alternatives within the DBH line or other brands we carry. We can also advise you on lip material and spring type according to the fluid and working temperature. The idea is that you do not buy blindly: first we validate the part and then we quote.
