The DBH 9945Vit is a radial shaft seal built for a 74 mm shaft and identified by the A 351-H AH design. It keeps lubricant in and contaminants out of rotating equipment, which helps protect bearings and bushings. MR Industrial Accessories supplies this seal as part of its seals and oil seals range, and can help you confirm dimensions or find equivalents.

This seal carries the DBH designation 9945Vit. The reference data lists an A 351-H AH design and a shaft diameter of 74 mm. Housing and height are shown as 0 and 000, so they are not treated as valid figures; those values are confirmed against the manufacturer's technical data when you inquire. Construction is a lip seal with a metal case and elastomer, made for rotating shafts.

You will find seals like this in gearboxes, pumps, electric motors, rollers and transmission equipment. They do two jobs: stop oil or grease from leaking out, and block dust, water or particles from getting in. In applications with vibration or moderate temperature, the right seal selection supports bearing life and cuts downtime. Treat it as a wear part and check it at every preventive maintenance interval.

Installation calls for checking three things: shaft diameter, housing bore and available width. Lubricate the lip, make sure the shaft has no burrs or marks, and use an installation tool that presses on the outer edge rather than the lip. If the shaft is worn, an auxiliary lip design may be the better choice. Final selection depends on speed, temperature and the fluid being retained.

For an equivalent, send the part number 9945Vit along with the actual shaft and housing dimensions and a photo of the part. With that information we can search alternatives in the DBH line or other brands we supply, and we can also tell you if the original seal is no longer available. The goal is to keep your equipment running without a long stop for a standard part.
