The DBH 6738Pol is a radial shaft seal built to keep oil or grease contained where a rotating shaft passes through a housing. Its designation covers a 110 mm shaft, a 130 mm housing and a 13 mm height, with an Mx lip and body configuration. You will find this size in gearboxes, pumps, motors and other power transmission equipment where lubricant retention and exclusion of dust or water matter. MR supplies it within its seals and oil seals range.

The order code is 6738Pol, and the dimensions to match are shaft 110 mm, housing 130 mm and width 13.00 mm. The Mx design describes how the lip and seal body are arranged. As a radial seal, it works against a rotating shaft inside a cylindrical bore. DBH is one of the brands MR carries, so the designation itself is what you use when ordering.

Seals in this size range turn up on medium-section shafts: gearboxes, reducers, centrifugal pumps, electric motors, rollers and conveyors. In those positions the seal does two jobs at once: it holds lubricant in the assembly and blocks contaminants from the outside. For moderate shaft speeds and normal operating temperatures, a lip seal is the straightforward way to close that gap.

Before installing a radial shaft seal, inspect both mating surfaces. The shaft should be free of burrs, scratches and wear across the lip contact band, and the housing bore must be clean and undistorted. Seat the seal with the lip toward the lubricant side, keep it square in the bore and avoid striking the sealing lip directly. When choosing the seal, consider the lubricant type, shaft speed and working temperature alongside the dimensions, since those factors influence how long the seal lasts.

For an equivalent, send the code 6738Pol along with your shaft and housing dimensions. That information lets us match a seal from the same series or from another brand with the required dimensions and design. A photo of the old seal or the housing, showing the diameters and width clearly, also helps. It lowers the chance of receiving a part that does not fit or seal properly.
