The DBH 6856 radial shaft seal is a lip seal designed to close off the passage of oil or grease in equipment with a rotating shaft. With dimensions of 120.50 mm shaft, 152.36 mm housing and 13.00 mm height, and an Lx design, it is press-fitted into the housing and works against the shaft to retain lubricant and block the entry of dust or water. It is a common replacement part in industrial maintenance.

This item is a DBH 6856 radial shaft seal, identified by its designation 6856. Its dimensions are 120.50 mm shaft diameter (d), 152.36 mm housing diameter (D) and 13.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and a construction configuration specific to the series. It is a radial-type seal, intended for rotating shafts with permanent lubrication. DBH is an official brand that MR supplies, so the spare part is available with that origin.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases it fulfills the function of retaining the oil inside the assembly and preventing external agents such as dust, chips or water from entering the bearings or gears. It is a critical part in preventive maintenance, since its failure causes lubricant loss and premature wear of internal components.

To correctly select and mount this seal, verify that the shaft and housing dimensions match those of the equipment. The Lx design defines the type of lip and its orientation, so it is advisable to respect the original mounting position. During installation, lubricate the lip with the same grease or oil used in the system, avoid striking it and make sure the shaft has no burrs or wear. If the housing has play or roughness, the sealing may not be effective.
