The DBH 5938 radial shaft seal is a lip seal that mounts in a component's housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a housing. This item has a shaft diameter of 31.75 mm, a housing diameter of 48.08 mm and a height of 12.70 mm, with Mz design.

The DBH 5938 is a radial lip seal with the following dimensions: shaft diameter 31.75 mm, housing diameter 48.08 mm and height 12.70 mm. The Mz design corresponds to a single lip configuration with a spring, intended for rotating shafts with lubrication. The designation 5938 identifies this size within the DBH line. The elastomeric lip runs on the shaft surface and the internal spring maintains contact pressure to compensate for wear.

These seals appear in gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. They are also found in mixers, conveyors and agricultural or process machinery. In all cases they perform the same function: separating the lubricated interior from the outside environment, preventing leaks and contamination. When the seal fails, a visible oil loss usually appears on the housing or the floor, and in equipment exposed to dust or water, particles enter and accelerate wear on bearings and gears.

To select a seal you must verify three dimensions: shaft diameter, housing diameter and height. The condition of the surface where the lip runs also matters: if the shaft has scratches, wear or burrs, the new seal will not seal properly. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and tap only on the outer ring, never on the lip. If the housing has burrs, clean it before mounting. A poorly seated seal can pop out or deform.

If you need a nearby size or an equivalent to the 5938, send us the shaft, housing and height dimensions, plus a photo of the old seal if you have it on hand. With that data we search within the DBH line or another compatible alternative. We can also advise you if the Mz design is not suitable for your application, for example if there is high pressure or high peripheral speed. The more complete the information, the faster we can send you the right option.
