The DBH 9974 is a radial shaft seal built for rotating shafts. It measures 80 mm at the shaft, 127 mm at the housing, and 17.00 mm in height, with an A 111 design. Its role is to keep lubricant in and contaminants out, protecting bearings and bushings in equipment that runs continuously.

This seal is identified by its dimensions: shaft 80 mm, housing 127 mm, width 17.00 mm. The A 111 designation indicates the lip and case configuration. The sealing lip contacts the shaft while the metal case presses into the housing. It is a standard wear part in the radial shaft seal category, used where permanent lubrication and a barrier against dust, water, or particles are required.

You will find the DBH 9974 in gearboxes, pumps, electric motors, transmission equipment, and process machinery where a shaft passes through a lubricated housing. It also suits applications exposed to dust or splashes, keeping lubricant from escaping and the environment from entering the bearing. It is common in corrective maintenance of continuously running equipment.

During installation, inspect the shaft for burrs or wear and ensure the housing is clean and undistorted. Lubricate the lip before pressing the seal in and keep it perpendicular to the shaft, avoiding impacts on the lip. If the shaft shows a pronounced wear groove, a seal with the lip in a different position may be necessary. Selection depends on the lubricant type, speed, and operating temperature.

For an equivalent, provide the part number 9974, the shaft and housing dimensions, and a photo of the old seal. With that information, we review alternatives within the DBH line or from other brands we supply. We can also help if the housing diameter differs or the available width is smaller.
