The DBH 8985 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With an 85 mm shaft, 120 mm housing and 12 mm height, and Lx design, it covers applications where axial space is limited and reliable sealing is needed in rotating equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line.

The DBH 8985 is a single-lip radial shaft seal with the following dimensions: shaft diameter 85 mm, housing diameter 120 mm and height 12.00 mm. The Lx design corresponds to a lip and case configuration intended for oil or grease retention on rotating shafts. It is press-fitted into the housing and its flexible lip runs on the shaft surface, creating a dynamic seal that prevents leaks and the entry of contaminants. It is a wear part that should be replaced when lubricant loss appears or play or roughness is detected in the contact area.

This type of oil seal is used in gearboxes, pumps, electric motors, rollers, mixers and power transmission equipment. It also appears in agricultural machinery, conveyors and hydraulic systems where a shaft rotates inside a housing and the lubricant must be separated from the environment. In industrial plants it is usually part of preventive maintenance: it is replaced together with bearings and bushings when an assembly is dismantled. If the equipment works with a lot of dirt or water, the oil seal is the first barrier and its condition defines the service life of the bearing.

For installation, check that the housing is clean, free of burrs and has the correct 120 mm dimension; the shaft must be polished, without splines or wear on the sealing surface, with 85 mm nominal. Lubricate the lip before inserting it and apply force on the outer ring, never on the lip. The 12.00 mm height must match the space available in the housing. If the shaft shows a groove or wear, consider a repair sleeve or an alternative size before fitting the new oil seal.
