The DBH 9800 is a radial shaft seal built around a rotating shaft. It keeps lubricant where it belongs, inside the housing, and blocks dust, water and other particles from getting in. Shaft 66 mm, housing 85 mm, height 8.00/10.00 mm. Gearboxes, pumps, electric motors and power transmission equipment are the usual homes for this seal. MR supplies the DBH line and can help you match the right seal to the job.

The code 9800 identifies this radial shaft seal, and design A 303 tells you what it is: a single lip with a spring, made for rotating shafts that run with lubrication. The 8.00/10.00 mm height is a range, so the profile fits housings of either depth within it. The elastomer compound stands up to oils and greases, which is what makes this a wear part worth specifying correctly.

Where you will see it: gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. In each case the job is the same, holding lubricant in and keeping contaminants out so bearings and gears stay clean. Dusty or damp conditions at moderate shaft speeds are typical, and it also shows up on agricultural machinery, conveyors and process lines that get serviced on a schedule.

Reading the size before you order: shaft diameter (d) 66 mm, housing bore (D) 85 mm, height (h) 8.00/10.00 mm. Check both the shaft and the housing against the equipment, since the height range covers housings with or without a shoulder as long as the lip sits on a ground, lubricated surface. Seat the lip without striking it, and keep the spring facing the fluid you want to retain. A worn shaft may call for a repair sleeve or a different size. Peripheral speed and operating temperature also matter, depending on the elastomer.

Need an equivalent? Send the code 9800 or the dimensions 66x85x8/10 mm on WhatsApp. We can point you to alternatives in the same brand or other compatible options while keeping your equipment's critical dimensions intact, and we can tell you whether the housing accepts a different height or design. The final call should always be checked against real conditions: lubricant type, temperature, speed and how dirty the environment is.

The DBH brand sits within our seals and radial shaft seal range. If this one is not an exact fit, send the code or the dimensions and we will help you track down the right part, along with bearings and power transmission components if you need them.
