In all cases, its function is to protect bearings and gears from the entry of dirt and to prevent oil or grease leaks. It is commonly found in agricultural machinery, mining equipment, process plants and hydraulic systems where working conditions demand durable sealing.

To correctly select an oil seal such as the DBH 9638, check that the shaft and housing dimensions match those of the component to be sealed. The stepped height must allow mounting without interference. It is important to check the condition of the shaft surface: it must not show wear, scratches or burrs that damage the lip. During mounting, lubricate the lip with the same oil or grease used in the application and use a suitable tool so as not to deform it. If the shaft has a groove or a shoulder, consult our technical team.
