The DBH 8181 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent contaminants from entering rotating equipment. Due to its dimensions —110 mm shaft, 162 mm housing and 13.00/18.50 mm height— it is used in gearboxes, pumps and medium-to-large transmissions. MR Accesorios Industriales supplies this official brand and advises you so that you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified with the code 8181. Its dimensions are: shaft diameter 110 mm, housing diameter 162 mm and height 13.00/18.50 mm, with A 157 design. That double height indicates that the seal has an auxiliary lip or a stepped section that improves sealing under conditions of dirt or vibration. The A 157 design corresponds to a specific lip and case geometry defined by the manufacturer for this size.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, transmission shafts and continuous process equipment. In all cases it fulfills the function of retaining the oil or grease inside the assembly and blocking dust, water or particles that shorten the life of the bearings. It is a wear part: it is advisable to replace it when leaks appear or when the equipment is dismantled for scheduled maintenance.

To fit it, verify that the shaft diameter and the housing diameter match the values indicated and that the shaft surface is clean, free of burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil as the equipment before inserting it and place the seal perpendicular to the shaft, without hitting it directly. If the housing has a chamfer, respect the angle so as not to turn the lip inside out during installation.
