The DBH 6905 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 12 mm shaft, a 19 mm housing bore and a 4.50 mm height, so it works well where space is tight. You will find it in pumps, motors, gearboxes and other power transmission assemblies. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your machine.

This seal carries the DBH brand and the code 6905. Its three key measurements are shaft 12 mm, housing 19 mm and width 4.50 mm. The Lt design means a single sealing lip, which suits arrangements with limited axial room. An elastomer lip runs against the shaft to block oil or grease from escaping and to keep dust and water out. The metal outer case holds the seal firmly in the housing bore.

You will commonly see this seal in small electric motors, centrifugal pumps, speed reducers, fan shafts and power transmission units. Machine tools, packaging lines and lubrication systems also use it. Its compact size makes it a good fit for mechanisms where radial and axial space is at a premium. In every case, the seal protects the bearings and helps the assembly last by stopping lubricant loss and keeping abrasive particles away.

When choosing a seal, check the shaft diameter, the housing bore and the height. The shaft surface should be ground and hard enough to avoid early lip wear. Put a chamfer on the housing entry so the seal does not get damaged during installation. Peripheral speed and operating temperature guide the lip material choice. MR Industrial Accessories can advise you on the most suitable configuration for your equipment.

If you need a replacement, send us the code 6905 or the current dimensions. We carry alternatives from other brands and can search for the option that fits your application. We can also tell you whether the available space allows a seal with a different design or material. The goal is to keep your equipment from going down because of a part you cannot find.
