The DBH 8172 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts of small diameter. With dimensions of 7.90 mm shaft, 14.30 mm housing and 5.00 mm height, and an Lt design, it is used in mechanisms where axial space is limited and a reliable seal is required. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a DBH 8172 radial shaft seal, identified by its code 8172. Its main attributes are: shaft diameter (d) of 7.9 mm, housing diameter (D) of 14.3 mm and height (h) of 5.00 mm. The Lt design corresponds to a single lip configuration with spring, suitable for applications where the shaft rotates and a barrier against oil, grease or dust is needed. These dimensions allow it to be mounted in compact housings, such as those found in small motors, pumps or gearboxes.

Typical applications of a seal of this size include low-power electric motors, small centrifugal pumps, miniature gearboxes, pneumatic tools and instrumentation equipment. In all cases, the seal's function is to keep the lubricant inside the assembly and prevent the entry of external particles that could damage bearings or gears. Its Lt design is suitable for moderate speeds and low pressures, provided the mounting conditions are respected.

To correctly select and mount this seal, keep in mind that the shaft diameter must be within the recommended tolerance to avoid leaks or premature wear. The housing must have a suitable surface finish and a depth that allows the 5.00 mm height to be seated without deforming the lip. It is essential to lubricate the lip before installation and to use a mounting tool that does not damage the seal. Also, verify that the direction of rotation and the operating temperature are compatible with the seal material.
