The DBH 9723Pol is a radial shaft seal with a lip that sits on the shaft and presses against the housing bore. It keeps lubricant in and keeps dust, water and other particles out. Its Mx-Bidi lip works in either direction of rotation, so you do not have to worry about which way the shaft turns when you install it. It fits a 54 mm shaft and a 90 mm housing, and is commonly found in gearboxes, pumps, motors and power transmission equipment.

This seal carries the code 9723Pol from DBH. The dimensions are shaft 54 mm, housing 90 mm and height 12.50 mm. The 12.50 mm height tells you how much axial space it takes up in the housing cavity. The Mx-Bidi design means the lip seals whether the shaft rotates clockwise or counterclockwise, which is helpful when the direction of rotation is not fixed or when the seal could be installed either way.

You will see seals like this in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission equipment. They also show up in agricultural machinery, process lines and pumping systems where oil or grease has to stay inside and contamination has to stay outside. Because it is a wear part, check it whenever the assembly is opened: look for hardening, cuts or a lip that has lost its flexibility.

When choosing a replacement, match the shaft and housing dimensions and make sure the height fits the cavity depth. The Mx-Bidi design is the right choice when the shaft can turn in both directions. If rotation is always one way, another lip configuration may work. During installation, lubricate the lip, do not strike it, and confirm the shaft is free of burrs or marks that could damage the sealing edge.

For an equivalent, send the code 9723Pol along with your shaft, housing and height dimensions and a description of the application. With that information we can check the DBH line or other brands we carry. We can also tell you if the Mx-Bidi design is not the best fit for your equipment.
