The DBH 5891 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 70 mm shaft, 89 mm housing and 12.50 mm height place it in medium-size transmission equipment and pumps. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal for the mounting.

This item is a DBH 5891 radial shaft seal with the following dimensions: 70 mm shaft diameter, 89 mm housing diameter and 12.50 mm height. The Lz design corresponds to a single lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip bears on the shaft and the spring maintains contact pressure; the outer body is press-fitted into the machined cavity. It is a wear component that protects bearings and gears from contamination and oil loss.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, mixers, conveyors and belt or chain drive equipment. It is also used on fan shafts, compressors and machine tools where the oil bath must be separated from the environment. In all cases, verify that the shaft has no splines, burrs or wear and that the sealing surface is polished, because a scratched track ruins the lip within a few hours of running.

To select the seal, in addition to the three dimensions, take into account shaft speed, working temperature and the fluid to be retained. The Lz design is suitable for general applications with mineral lubricant; if there is heavy abrasion or pressure, another profile may be better. During assembly, lubricate the lip with the same oil as the equipment, insert it perpendicular to the shaft with a tube bearing on the outer ring and avoid striking it. A poorly seated seal leaks or pops out even if the dimensions are correct.

If part number 5891 is not available or you need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part and the housing. With that we look for an equivalent in the same brand or in another line we carry. We can also evaluate design variants if the equipment runs at higher temperature or speed. Do not post estimated dimensions: the more exact the data, the faster the response.
