The DBH 9663Vit is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a housing. It fits a 91 mm shaft, a 111 mm housing bore and a 10.00 mm width, and its A 278-R design defines the lip and metal case geometry. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

This seal carries the DBH designation 9663Vit. Its three key dimensions are shaft 91 mm, housing 111 mm and width 10.00 mm. The A 278-R design describes how the sealing lip and outer case are built. In service, the seal sits in the housing and rides on the shaft, holding oil or grease in place while blocking dust, water and particles.

You will find radial shaft seals of this type in gearboxes, pumps, electric motors, rollers and power transmission equipment, as well as in agricultural machinery, process equipment and conveyors. Any time a rotating shaft passes through a housing and the lubricant must stay separate from the environment, a seal like the 9663Vit does that job. Shaft diameter, housing bore and operating conditions drive the selection.

When installing, make sure the shaft and housing are clean and free of burrs. Lubricate the lip before you slide the seal in, and press on the outer diameter with a proper installation tool, never on the lip. The 10.00 mm width has to match the housing depth. If the shaft is worn, a repair sleeve or a different size may be the better route. Good alignment between shaft and housing helps the seal last.
