For maintenance and purchasing teams, the DBH 5938 radial shaft seal is a replacement lip seal that keeps lubricant in and contaminants out of rotating equipment. It fits into a housing and rides against the shaft, making it a common repair part for gearboxes, pumps, motors and other power transmission assemblies. The seal's dimensions are 31.75 mm for the shaft, 48.08 mm for the housing bore and 12.70 mm for the height. Its Mz design indicates a single lip with a spring.

The 5938 code pinpoints this particular size in the DBH line. The Mz configuration uses one elastomeric lip backed by a spring, a setup intended for lubricated rotating shafts. As the shaft turns, the lip maintains contact and the spring compensates for gradual wear. That combination helps hold oil or grease inside the assembly while blocking dust, water and other particles from entering.

These seals are found in gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive systems, as well as in mixers, conveyors and process or agricultural machinery. In every case, the goal is the same: separate the lubricated interior from the outside environment. A failed seal often shows up as oil on the housing or the floor. In dirty or wet conditions, the resulting contamination can speed up wear on bearings and gears.

When choosing a replacement, confirm three measurements: shaft diameter, housing bore and overall height. Also inspect the shaft surface where the lip runs; scratches, wear or burrs can prevent a proper seal even with a new part. During installation, coat the lip with the same lubricant used in the equipment, keep the seal perpendicular to the shaft and apply force only to the outer ring, never to the lip. Remove any burrs from the housing before fitting. A seal that is not seated squarely may deform or work loose.

If you need an alternative to the 5938, send the shaft, housing and height dimensions, and a photo of the old seal if available. With that information, we can search the DBH line or another compatible option. We can also help determine whether the Mz design suits your operating conditions, such as elevated pressure or high shaft speed. The more details you provide, the faster we can identify the right part.
