The DBH 5112Sil radial shaft seal is a lip seal mounted on a rotating shaft to keep lubricant inside the housing and stop dust, water or particles from entering. Thanks to its compact size and Lz design, it is used in small gearboxes, electric motors, pumps and transmission equipment where axial space is limited. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right oil seal for your shaft and housing.

This item is a DBH 5112Sil radial shaft seal with the following dimensions: shaft diameter 25.40 mm, housing bore diameter 44.50 mm and height 5.00 mm. The Lz design corresponds to a single-lip seal with a spring, intended for lubricated rotating shafts. The 5112Sil designation identifies the part within the DBH line. Before installing, verify that the shaft and housing match these dimensions, because a seal with different dimensions will not seal properly even if it looks similar.

Typical applications for a seal of this size are low- and medium-power electric motors, gear reducers, centrifugal pumps, small compressors, fan shafts and power transmission equipment. It also appears in machine tools and agro-industrial equipment where oil or grease must be retained and contaminants kept out. In all these cases it works on a rotating shaft and inside a machined housing, with the lip resting evenly.

To select and install this oil seal, take into account the shaft speed, the operating temperature and the type of lubricant. The lip must be lubricated before assembly, and it is advisable to use an installation tool that does not damage it. Check the condition of the shaft: if there is wear, scratches or burrs in the sealing area, the new seal will fail quickly. The Lz design with a spring maintains contact, but it needs a polished, undamaged surface to last.
