The DBH 8634 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain oil or grease and block dust and water from entering. Its A 103 design and dimensions of 38 mm shaft, 65 mm housing and 12/19 mm height make it suitable for gearboxes, pumps and power transmission equipment. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

This item is a DBH radial shaft seal, identified with the designation 8634 and the A 103 design. Its nominal dimensions are 38 mm shaft diameter (d), 65 mm housing diameter (D) and a height (h) of 12.00/19.00 mm. That variable height indicates a profile with a mounting section and a longer lip, typical of seals with a reinforced body. The sealing lip runs on the shaft and the outer case fits into the housing to prevent leaks.

The most common applications for this oil seal include gearboxes, reducers, centrifugal pumps, electric motors and belt or chain drive equipment. In all cases, its function is to confine the lubricant inside the assembly and prevent external contaminants such as dust, chips or water from entering the bearings and gears. It is a wear part that should be checked at every preventive maintenance interval.

To correctly select and install the DBH 8634 oil seal, verify that the shaft diameter is 38 mm and the housing is 65 mm, with a height of 12/19 mm according to the A 103 design. The shaft must be clean, free of burrs or marks, and lubricated before inserting the seal. The lip face must point toward the fluid side to be retained. Avoid striking the lip during installation and make sure the seal sits square in the housing.
