The DBH 8633 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and moisture from entering rotating equipment. Its A 065 design and variable height of 9 to 24 mm make it suitable for housings with different mounting depths. It installs on 48 mm shafts and fits into 62 mm bores, covering demanding applications in industry and maintenance.

This DBH 8633 oil seal has a shaft diameter of 48 mm, a housing diameter of 62 mm and a height ranging from 9.00 to 24.00 mm depending on the A 065 design. That variable height allows it to adapt to housings with a shoulder or to configurations where the lip must sit in a specific position. The A 065 design corresponds to a profile with a sealing lip and reinforced body, designed to retain lubricant and exclude contaminants in environments with moderate vibration.

It is used in gearboxes, pumps, electric motors, drive shafts and continuous process equipment. It also appears in agricultural machinery, conveyors and hydraulic systems where there is constant rotation and the presence of oil or grease. As it is a wear component, it should be checked at every preventive maintenance interval: an incipient leak or a hardened lip anticipates failure and allows the replacement to be scheduled without unplanned downtime.

To select it, verify that the shaft and housing diameters match the values on the product page. The 9.00/24.00 mm height gives you margin to adjust the lip position inside the bore. During installation, lubricate the lip with the same grease or oil used in the equipment, avoid striking it and make sure the shaft has no burrs or splines that could damage the seal. If the housing is worn, consider a repair sleeve before installing the new seal.
