The DBH 6109 is a radial shaft seal built to keep lubricant in and contamination out of rotating assemblies. Its dimensions are 57.15 mm at the shaft, 101.81 mm at the housing bore and 22.22 mm in height, and it uses the A 021 design. You will find seals of this size in gearboxes, pumps, motors and transmissions. MR Industrial Accessories supplies this brand and helps you match the seal to the application.

The designation 6109 identifies this seal, and the A 021 design describes how it is built: a sealing lip combined with a metal outer body. That body presses into the housing bore, while the lip rides against the rotating shaft. The three numbers to check before ordering are shaft 57.15 mm, housing 101.81 mm and height 22.22 mm. It belongs to the radial shaft seal category, so it is a common replacement item on maintenance shelves.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, reducers and other power transmission equipment. The job is the same in every case: hold oil or grease inside the assembly and keep dust, water and particles out. Those contaminants are what shorten bearing and gear life, so the seal protects the parts behind it. Fan shafts, mixer shafts and conveyor drives with continuous rotation are also typical locations.

Before installation, confirm that the shaft and housing dimensions match the equipment. The shaft surface should be clean and free of burrs or deep marks. Lubricating the lip first helps it slide into place without damage. Use a press or a suitable driver and apply force evenly on the outer diameter, never on the lip itself. If the shaft is already worn, a seal with an auxiliary lip may be the better choice, and MR can advise on that.
