The DBH 9443 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Due to its dimensions —55 mm shaft, 85 mm housing and 8 mm height— and its Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment that require reliable, low-maintenance sealing.

The DBH 9443 is a radial shaft seal with an Lx design, featuring a sealing lip and metal body. Its dimensions are 55.00 mm shaft diameter (d), 85.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a seal with a single lip and spring, intended for rotating shafts with oil or grease lubrication. It is press-fitted into the housing and works with the lip resting on the shaft, creating a dynamic seal that prevents leaks and contamination.

This type of seal is found in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. It is also used in machine tools, compressors and conveyor systems. Its function is to retain lubricant inside the assembly and protect bearings or bushings from the entry of dust, water or chips. It is a wear part that should be checked when oil leaks or abnormal noises appear in the seal area.

To select the correct seal, verify that the shaft, housing and height dimensions match those of the assembly. The Lx design is suitable for shafts with moderate speeds and continuous lubrication; if the equipment operates with heavy contamination or high speeds, a different lip profile or material may be required. During installation, lubricate the lip, avoid striking it and make sure the shaft has no burrs or wear. Press-fitting with the proper tool extends the service life of the seal.
