The DBH 9800 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. With dimensions of 66 mm shaft, 85 mm housing and a height of 8.00/10.00 mm, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a DBH 9800 radial shaft seal, identified by its designation 9800. Its dimensions are: shaft diameter (d) 66 mm, housing diameter (D) 85 mm and height (h) 8.00/10.00 mm. Design A 303 corresponds to a single-lip seal with spring, suitable for rotating shafts with lubrication. The double height (8.00/10.00 mm) indicates that the profile can be mounted in housings with different depths within that range. Made of elastomer resistant to oils and greases, it is a key part for maintaining sealing in industrial equipment.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive systems. In all cases, its function is to confine the lubricant and protect bearings and gears from the entry of external contaminants. It is commonly found in equipment where the shaft rotates at moderate speeds and there is exposure to dust or moisture. It is also used in agricultural machinery, conveyors and continuous process equipment that require periodic maintenance.

To correctly select a seal, verify that the shaft and housing dimensions match those of the equipment. The 8.00/10.00 mm height allows adaptation to housings with or without a shoulder, as long as the lip rests on a ground and lubricated surface. During mounting, avoid striking the lip and make sure the spring is on the side of the fluid to be retained. If the shaft shows wear, evaluate a repair sleeve or an alternative size. Peripheral speed and working temperature are factors to consider depending on the elastomer.
