For maintenance teams dealing with leaks around rotating shafts, the DBH 9551 oil seal offers a reliable solution. This radial lip seal is designed to sit in the housing and maintain contact with the shaft, keeping lubricant in and contaminants out. Its dimensions—38.10 mm shaft, 50.36 mm housing, and 6.35 mm width—make it a common fit for medium-sized pumps and transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your specific application.
The DBH 9551 is identified by code 9551 and features an Mx design. That Mx designation indicates a single lip with a spring, a configuration often used on rotating shafts that require lubrication. The seal combines a flexible lip elastomer with a metal outer case, allowing it to maintain dynamic contact and tolerate minor misalignment during operation.
Seals in this size range are frequently found in gearboxes, centrifugal pumps, electric motors, fan shafts, and power transmission components. They also appear in agricultural equipment, process lines, and pumping systems where oil must be contained. Because it is a wear part, the seal should be checked whenever leaks appear or when the shaft shows signs of rubbing in the contact zone.
When selecting a replacement, match the shaft diameter, housing bore, and width to the original seal. Inspect the shaft surface; scratches or wear will shorten the life of any new lip. During installation, apply lubricant to the lip, press the seal in squarely, and avoid uneven force that could distort the case. If your equipment runs with high vibration or elevated temperatures, ask about alternative compounds.
To request a quote for code 9551, send the dimensions of your old seal or a photo of the part. With that information, we can cross-reference the part number with equivalent brands and series. We can also review Mx design options or other lip configurations based on your lubricant and shaft speed. The goal is to help you avoid unplanned downtime.
