The DBH 8343 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. With a 63 mm shaft diameter, 90 mm housing diameter and 7.70 mm height, it is a common size in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales sells this brand and helps you confirm it is the right size for your equipment.

This item is a DBH 8343 radial shaft seal, identified by its designation 8343 and its A 099 design. Its dimensions are 63 mm shaft diameter (d), 90 mm housing diameter (D) and 7.70 mm height (h). It is a single-lip seal designed for rotating shafts: the flexible lip rides on the shaft and creates the seal, while the outer body is fixed in the housing. It is used with oil or grease and does not replace a mechanical seal where there is fluid pressure.

Typical applications for a seal of this size are gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all of these cases it performs the same function: keeping oil in and preventing contaminants from entering that accelerate wear on bearings and gears. It is also used as a secondary barrier in equipment heavily exposed to dust or water, provided the shaft and housing are in good condition.

For correct installation, check that the shaft has no burrs, scratches or wear in the lip area, and that the housing is clean and free of deformation. Lubricate the lip before inserting it and fit the seal perpendicular to the shaft, using a tube or press that bears on the outer edge, never on the lip. If the shaft shows a pronounced groove, it is worth evaluating a neighboring size or a seal with the lip in a different position so it seals on a healthy track.
