The DBH 9230 radial shaft seal is a lip seal designed for rotating shafts with a diameter of 28.5 mm. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. It is press-fitted into a housing with a 38 mm outer diameter and has a height of 5.00/5.50 mm. It is a key component in gearboxes, pumps and electric motors, where reliable sealing extends the service life of bearings and gears.

This DBH 9230 oil seal has an A 186 design and is identified by its dimensions: shaft diameter 28.5 mm, housing diameter 38 mm and height 5.00/5.50 mm. The sealing lip, made of elastomer, runs on the rotating shaft, while the metal outer case ensures a firm fit in the housing. The stepped height allows it to adapt to different housing depths. It is a common replacement part in industrial equipment that requires efficient sealing in tight spaces.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission systems. In all these machines, the 9230 oil seal protects the bearings and lubricant from external contamination, preventing leaks and premature wear. It is also used in machine tools and continuous process equipment, where sealing reliability is critical to keeping production running without downtime.

To correctly select this oil seal, verify that the shaft diameter is 28.5 mm and the housing is 38 mm. The height 5.00/5.50 mm must match the depth of the cavity. During installation, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicularly and without striking the lip. If the shaft shows wear, consider a neighboring size or a seal with an auxiliary lip. Cleaning the housing is essential to prevent leaks.
