The DBH 6879 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 63 mm shaft diameter, 105 mm housing bore and 13.20 mm height, it is press-fitted into gearboxes, covers and housings to protect bearings and gears. Its A 101 design corresponds to a standard single-lip geometry with spring, suitable for industrial applications requiring reliable sealing and low friction.

This DBH 6879 oil seal has a shaft diameter of 63 mm, a housing bore of 105 mm and an overall height of 13.20 mm. The A 101 design corresponds to a single-lip seal with steel spring, intended for rotating shafts at moderate peripheral speeds. The designation 6879 identifies the exact size within the DBH line, and it is the reference you will find in the manufacturer's catalogue. It is made of elastomer resistant to mineral oils and greases, and its metal case ensures a firm fit in the housing.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: to prevent lubricant leaks to the outside and to block the ingress of dust, water or particles that accelerate wear of bearings and gears. In the food, chemical or heavy machinery industries, choosing the correct seal extends equipment service life and reduces maintenance downtime.

To select this seal correctly, verify that the shaft diameter is within the recommended tolerance and that the housing has the appropriate surface finish. Installation is done with a uniform pressure tool, pre-lubricating the lip and avoiding impacts that could damage it. If the shaft shows wear or roughness, consider a seal with an additional lip or a wear sleeve. Rotation speed and operating temperature also determine the choice of lip material.
