MR Industrial Accessories supplies this brand and can help you select the correct seal for your application.

Part number 8643 belongs to the DBH line of radial shaft seals. Its designation follows the standard sequence: shaft 50.00 mm, housing 67.00 mm, height 11.00 mm. The A 183 design code indicates a particular lip configuration, material and spring type, though those specifics should be confirmed with the manufacturer's data sheet. This is a standard replacement seal for shafts that turn inside a bore and need a dependable barrier.

You will find seals like the DBH 8643 in gearboxes, pumps, electric motors, reducers and power transmission equipment. In each case, the seal sits on a rotating shaft and separates oil or grease from the surrounding environment. It is also common in agricultural machinery, road equipment and process lines where dust or water ingress can reduce bearing life.

Proper installation starts by confirming the shaft is 50 mm and the housing bore is 67 mm. The shaft surface must be clean and free of burrs or marks, and lubricating the lip before insertion is recommended. Fit the seal with the lip facing the lubricant side and seat it fully against the housing bottom. If the shaft is worn, a seal with an auxiliary lip may be a better choice.
