The DBH 9297 radial shaft seal is a lip seal designed for 12 mm rotating shafts, with a 36 mm housing bore and 7 mm height. Its function is to retain the lubricant inside the assembly and prevent dust, water or particles from entering that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, which must be ground and lubricated. It is a common replacement part in electric motors, pumps and small and medium-power gear reducers.

This item is a radial shaft seal from the DBH line, identified by part number 9297. Its dimensions are 12 mm shaft, 36 mm housing bore and 7.00 mm height. The Lx design corresponds to a single-lip seal with spring, without an external dust lip, intended for applications where the seal must take up little axial space. DBH is an official brand that MR carries, so the product is supplied with its original designation and not as a generic alternative.

Typical applications for a seal of this size include small electric motors, centrifugal pumps, speed reducers, compressors and power transmission equipment. In all cases, the seal separates the oil or grease from the outside environment and protects nearby bearings or bushings. It is also used in machine tools, washing equipment and irrigation systems, where dust or moisture shortens the service life of rotating components.

To correctly select a seal, you must check the shaft diameter, the housing bore diameter and the available height. The shaft must have adequate surface hardness and a fine surface finish so that the lip seals without wearing prematurely. The housing must be clean, free of burrs and have an entry chamfer that facilitates installation. Rotation speed and working temperature also determine the choice of lip material.

During installation, lubricate the lip with the same oil or grease used in the equipment and press the seal in perpendicularly until it seats at the bottom of the housing. Avoid striking the lip with metal tools and do not run it dry. If the shaft shows a groove or wear, consider an adjacent size or a repair sleeve.
