When a rotating shaft passes through a housing, the DBH 5861 radial shaft seal keeps lubricant in and contaminants out. This lip seal protects bearings and bushings from dust, water, and particles that shorten service life. It is common in gearboxes, pumps, electric motors, and power transmission equipment where a dependable barrier is needed.
The DBH 5861 is a radial shaft seal identified by part number 5861. Its dimensions are shaft 30 mm, housing 50 mm, and height 12.00 mm. The Lz design defines how the lip seats on the shaft and how it performs under pressure and rotation. Use these three dimensions to find a direct replacement.
Seals of this size suit medium-section shafts in gearboxes, reducers, centrifugal pumps, electric motors, mixers, and conveyors. In these applications, the seal separates lubricant from the environment and shields bearings from incoming contaminants. Machine tools and process equipment also rely on it where lubricant cleanliness is critical to assembly life.
Correct installation depends on three checks. First, inspect the shaft for scores or burrs; a new lip cannot seal on a damaged surface, so verify diameter and finish. Second, confirm the housing is clean, free of impacts, and measures 50 mm as noted. Third, orient the lip according to the Lz design and the direction of rotation. Lubricate the lip before inserting it and avoid striking it during installation.
For an equivalent, send part number 5861 with the shaft, housing, and height dimensions from your equipment. We verify against the manufacturer's product page and suggest an alternative within the same radial shaft seal category. Also share the lubricant type and rotation speed, as they affect lip and material selection.
