The DBH 6856 is a radial shaft seal that keeps oil or grease contained where a shaft turns. Its dimensions are 120.50 mm for the shaft, 152.36 mm for the housing and 13.00 mm in height, and it uses the Lx design. The seal sits press-fitted in the housing and runs against the shaft, holding lubricant in and keeping dust or water out. It is a standard replacement item in industrial maintenance.

This seal carries the designation 6856. The three dimensions to check are shaft diameter (d) 120.50 mm, housing diameter (D) 152.36 mm and height (h) 13.00 mm. The Lx design refers to a specific lip and body configuration within the series. It is a radial-type seal for rotating shafts under permanent lubrication. DBH is one of the brands MR Industrial Accessories supplies, so this part is available from that source.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. Their job is to keep the oil inside the assembly and stop dust, chips or water from reaching the bearings or gears. Because a failed seal leads to lubricant loss and early wear on internal parts, it belongs on any preventive maintenance checklist.

Before ordering, confirm that the shaft and housing measurements match your equipment. The Lx design fixes the lip type and its orientation, so the original mounting position should be respected. When installing, coat the lip with the same oil or grease used in the system, avoid impacts, and check that the shaft surface is free of burrs or wear. A housing with play or roughness will not seal properly.
