The DBH 6656 is a rotary shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its Lx design pairs a sealing lip with a metal case that presses into the housing bore. Shaft 149.23 mm, housing 181.01 mm, height 15.87 mm. When a gearbox or pump starts weeping oil or drawing in grit, this is the kind of part that restores the seal.

Part number 6656 identifies the seal; the DBH name confirms the series. The three figures that matter are 149.23 mm for the shaft, 181.01 mm for the housing bore and 15.87 mm for the height. The Lx configuration tells you there is a lip and a metal reinforcement, which is what holds the lubricant in place and keeps dust and water from reaching the bearing cavity. It ships as a single seal.

You will find this size in gearboxes, speed reducers, centrifugal pumps, mixers and other power transmission drives. It also shows up on agricultural machinery, process lines and mining equipment. In every case the job is the same: protect bearings and gears from abrasive particles and from losing their oil.

Before installing, confirm that the shaft and bore match those three dimensions. The shaft should be clean, free of burrs or deep grooves, and lightly lubricated. A chamfer on the housing helps the lip slide in without damage. Use a proper installation tool and press evenly. If the machine runs hot or fast, check that the lip material suits the conditions.
