The DBH 8780 oil seal is a single-lip radial shaft seal that mounts on a 17 mm shaft and seals against a 29 mm housing, with a 5 mm height. Its Lx design works with the lip resting on the shaft to retain oil or grease and block the entry of dust and water. It is used in gearboxes, pumps, electric motors and power transmission equipment that require a reliable, low-maintenance seal.

This item is a DBH radial shaft seal with designation 8780. Its dimensions are 17 mm shaft, 29 mm housing and 5.00 mm height, with an Lx design. The sealing lip rests on the rotating shaft and the outer diameter fits into the housing, so the assembly retains lubricant and blocks external contaminants. It is a standard replacement part within the seal line that MR Accesorios Industriales supplies.

Typical applications for a seal of this size appear in equipment with small transmission shafts: electric motors, centrifugal pumps, gearboxes, compressors, machine tools and process equipment. It is also found in agricultural implements and conveyor lines. In every case it performs the same function: keeping oil in and dirt out, extending the life of bearings and gears.

For installation, 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 fit the seal perpendicular to the shaft, without deforming it. Selection depends on rotation speed, operating temperature and the type of lubricant; if the shaft shows a pronounced groove, it is worth considering a seal with the lip in a different position or a wear sleeve.
