This seal is identified by code 9666 in the DBH range. The main dimensions are a 168 mm shaft diameter, a 198 mm housing diameter, and a height that varies from 16.50 mm to 21.00 mm. The A 280 designation refers to the lip and body geometry, which is suited to those dimensions. It is a precision component that prevents lubricant leakage and blocks external particles.
Radial shaft seals like the DBH 9666 are found in gearboxes, pumps, electric motors, rollers, and other power transmission equipment. They are often specified in industries such as mining, cement, food processing, and water treatment, where large-diameter shafts require dependable sealing. They also serve in agricultural machinery and continuous process lines, helping protect bearings and extend assembly life.
Before installation, make sure the shaft and housing are clean and free of burrs. Coat the lip with the same oil or grease used in the equipment, then press the seal into place. The 16.50/21.00 mm height allows seating in cavities with a shoulder; verify the support face sits flush. If the shaft shows wear, a repair sleeve may be needed. Selection should account for speed, temperature, and fluid type, which can be checked against the manufacturer's data.
