The DBH 6878Vit is a radial shaft seal sized 55x80x10 mm, built to keep lubricant in and contaminants out of rotating equipment. Its flexible lip rides against the shaft, while an auxiliary lip adds an extra barrier against dust and moisture. This seal fits cylindrical housings and is commonly found in gearboxes, pumps, motors and other transmission assemblies where dependable sealing protects bearings and gears.

Key dimensions are shaft 55 mm, housing bore 80 mm and width 10 mm. The Lx-R H design pairs a radial sealing lip with an auxiliary exclusion lip for enhanced protection in dirty or wet conditions. The outer body is elastomeric, and the main lip is reinforced to handle continuous rotation. It serves as a direct replacement where these standard dimensions are required.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. In these systems, it stops oil or grease from escaping and keeps dirt out, which helps bearings last longer. It is also used in agricultural machinery, construction equipment and process lines where radial sealing is essential for reliable operation.

Before installation, check that the shaft surface is hard enough and has the right roughness, with no grooves or burrs that could harm the lip. Apply a little of the same oil or grease used in the equipment to the lip, then press the seal in perpendicular to the shaft using a tube that contacts the outer diameter. Do not strike the lip, and make sure the housing is clean and free of burrs. When replacing an existing seal, compare dimensions and lip style.
