The DBH 9971 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 28 mm shaft, a 47 mm housing bore, and has a height of 6.50/9.50 mm with design A 308. This profile is commonly found in gearboxes, pumps, electric motors, and power transmission assemblies where continuous rotation demands a dependable barrier.

The DBH line identifies this seal by code 9971. Its dimensions are shaft (d) 28 mm, housing (D) 47 mm, and height (h) 6.50/9.50 mm, with design A 308. The dual height indicates a stepped body with a lip section, made to sit in a housing that has a recess. The lip contacts the rotating shaft while the outer surface presses into the housing bore to create the seal.

You will find seals of this size in gearboxes, centrifugal pumps, electric motors, rollers, and other power transmission components. They also appear in machine tools and in systems where a bearing or bushing must hold oil or grease and stay protected from dust, water, or particles. Because it is a wear part, inspect it whenever the equipment is opened to avoid leaks and contamination.

When selecting a replacement, confirm that the shaft and housing diameters match the published values. The 6.50/9.50 mm height must seat in the cavity without distortion. Design A 308 sets the lip and body geometry, so do not substitute a different design without checking compatibility. During installation, lubricate the lip, use a proper insertion tool, and avoid striking the seal or installing it backward.

If you need an equivalent, send code 9971 with the shaft, housing, and height dimensions, plus the fluid type and operating temperature. With that information we can search for an alternative within the DBH line or from other brands we supply. We can also help if the housing recess is different or if space is limited.
