The DBH 6878Vit radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant within the assembly and prevent the ingress of dust, water or external particles. It is mounted in cylindrical housings and works on the shaft with a flexible lip that maintains dynamic contact. It is a key component in gearboxes, pumps, electric motors and transmission equipment, where reliable sealing extends the service life of bearings and gears.

This DBH 6878Vit oil seal has a shaft diameter of 55 mm, a housing bore of 80 mm and a height of 10 mm. Its Lx-R H design combines a radial sealing lip with an auxiliary exclusion lip, which improves protection against contaminants in demanding environments. The outer body is made of elastomeric material, and the main lip is reinforced to resist wear from continuous rotation. It is a direct replacement part for applications requiring these standardized dimensions.

Typical applications include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain transmission equipment. In these systems, the seal prevents oil or grease leaks and blocks the entry of dirt, extending bearing life. It is also used in agricultural machinery, construction equipment and process lines where radial sealing is critical to maintain operational reliability.

For correct installation, verify that the shaft has adequate surface hardness and controlled roughness, without grooves or burrs that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal perpendicular to the shaft, using an installation tube that supports on the outer diameter. Avoid hitting the lip and ensure the housing is clean and free of burrs. If the seal replaces another, compare the dimensions and lip design.
