The DBH 8669 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. Due to its dimensions —69.90 mm shaft, 98.45 mm housing and 12.70 mm height— it is used in gearboxes, pumps and power transmission equipment where bearings and gears must be protected. MR Accesorios Industriales carries this brand and quotes it on WhatsApp.

This item is a DBH 8669 radial shaft seal, with the dimensions shown in its designation: 69.90 mm shaft diameter, 98.45 mm housing diameter and 12.70 mm height. The Mz design corresponds to a single-lip configuration with a spring, intended for rotating shafts with oil or grease lubrication. The sealing lip works on the shaft and the metal case is fitted by interference in the housing. It is a replacement part, not a structural component: its function is to contain the lubricant and prevent contamination inside the equipment.

Typical applications for a seal of these dimensions appear in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. It is also found in machine tools, conveyors and process equipment where the shaft rotates on bearings and the passage between the lubricated interior and the environment must be sealed. In all these cases the seal protects the bearing and extends the service life of the assembly, provided the shaft and housing are in good condition.

To mount it, verify that the shaft has no burrs, deep scratches or wear on the sealing track, and that the housing is clean and free of deformation. Lubricate the lip before inserting it and use a support tube so as not to damage it. When selecting a replacement, in addition to the three dimensions, take into account the type of lubricant, the rotation speed and the working temperature. If the shaft is worn, consider a repair sleeve or a seal size with an offset lip.

If you need an equivalent or a nearby size, send us part number 8669 along with the shaft, housing and height dimensions you have. It also helps to indicate the equipment or the brand of the assembly where it is mounted. With that data we can look for an alternative within the same category of radial shaft seals or suggest a sleeve if the shaft is worn. The number does not have to match exactly: many times there is a very close size that solves the problem.
