For rotating shafts in industrial machinery, the DBH 8338 radial shaft seal keeps lubricant in and contaminants out. With a 40 mm shaft, 116 mm bore, and 13/17 mm height, it suits gearboxes, pumps, and motors. MR supplies this seal and helps you select the right one.

This DBH part number 8338 is a radial shaft seal with an A 135 configuration—a metal case and sealing lip. Its dimensions are shaft 40 mm, housing 116 mm, and height 13.00/17.00 mm. The dual height means it can fit housings of different depths, provided the shaft and bore match.

Typical uses include gearboxes, centrifugal pumps, electric motors, compressors, and power transmission equipment. In these applications, the seal retains oil or grease and shields bearings and gears from dust and moisture. It is common in industrial machinery and heavy vehicles where reliable sealing is needed on moderately rotating shafts.

Before installation, confirm the shaft is exactly 40 mm and the housing 116 mm. The shaft surface must be free of burrs or wear, or the lip will not seal. Lubricate the lip with the system's oil or grease, then insert the seal square to the shaft without hitting the lip. Choose the height within 13 to 17 mm to match the housing depth.
