The DBH 9930Pol is a radial shaft seal that keeps oil or grease in and dust or water out. It fits a 60 mm shaft, a 75 mm housing bore and an 8 mm height, and its Mx-Bidi design points to a double-lip or bidirectional layout. MR Industrial Accessories LLC supplies this seal within its seals and oil seals range for customers in the United States and Latin America.

Reading the 9930Pol code starts with the size: shaft 60 mm, housing 75 mm, height 8.00 mm. The Mx-Bidi designation describes a double-lip or bidirectional version, built to hold lubricant from either direction of rotation or to add sealing in reciprocating motion. Because the lip runs directly on the shaft and the outer edge sits in the bore, choosing the right size and fitting it squarely are what determine how long the assembly lasts.

You will find this type of seal in gearboxes, reducers, centrifugal pumps, electric motors, rollers and transmission shafts, as well as in agricultural machinery, material handling equipment and process lines. Treat it as a wear part: replace it when you see lubricant loss, unusual bearing noise or dirt collecting around the lip.

Before installation, confirm the shaft is clean, free of burrs and deep marks, and that the sealing surface has suitable roughness. Coat the lip with the same oil or grease used in the equipment, then seat the seal perpendicular to the shaft without hitting the lip directly. If the housing is worn, a seal with a sleeve is an option. Speed, temperature and the working fluid should be checked against the manufacturer's data sheet before you decide.

If you need an equivalent to the 9930Pol, send the part number, a photo of the part and the shaft, housing and height measurements. With that information we can search alternatives in the DBH line or other brands we carry, keeping the dimensions and design type. We can also help when the original seal is unmarked and the size has to be worked out from the housing.
