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

This item is a DBH radial shaft seal identified with the part number 6831Pist. Seals of this type combine an elastomeric lip, a metal reinforcement and a spring that maintains contact on the shaft. The commercial designation does not include dimensions in the record, so the inner diameter, outer diameter and width dimensions 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 Do not publish dimensions that are not verified: it is better to quote with the exact part number and validate the geometry before mounting.

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

To mount a radial shaft seal, check that the shaft has no burrs or wear and that the housing is clean and free of impacts. 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 nearby size or a seal with an offset lip. Correct alignment between shaft and housing prevents premature leaks and extends the life of the seal.

If you need an equivalent or a size different from 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 the lip material and the spring type according to the fluid and the working temperature. The idea is that you do not buy blindly: first we validate the part and then we quote.
