The DBH 5900 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Due to its dimensions —85 mm shaft, 120 mm housing and 13 mm height— it is used in gearboxes, pumps and medium-sized power transmission equipment.

This item is a DBH 5900 radial shaft seal, identified by its designation 5900. Its dimensions are 85 mm shaft diameter (d), 120 mm housing diameter (D) and 13 mm height (h). The indicated design is Lz, which defines the geometry of the lip and the seal body. It is a standard replacement component, intended for shafts rotating inside a machined cavity that require a continuous barrier against oil or grease leaks.

Typical applications for a seal of this size appear in gearboxes, reducers, centrifugal pumps, rollers and power transmission equipment. It is also found in process machinery, conveyors and mixers where the shaft protrudes from a lubricated housing. In all these cases it performs two functions: preventing lubricant from escaping outward and preventing external contamination from reaching the bearing or gear.

For proper installation, verify that the shaft and housing diameters match the values on the product page, that the shaft surface is polished and free of burrs, and that the housing is not damaged. The lip faces the lubricant side and should be lubricated before inserting the seal. If the equipment operates with high vibration or temperature, check the design and lip material against the manufacturer's data sheet before deciding.

If you need a nearby size or an equivalent, send us the part number 5900 along with the shaft diameter, housing diameter and height you have measured. With that data we search for alternatives within the same radial shaft seal category and confirm which options exist. We can also review whether the Lz design is suitable for your application or if another lip profile is preferable.
