When a small shaft needs reliable sealing, the DBH 9573 radial shaft seal is one of the options MR Industrial Accessories supplies. It is a lip seal of Mx design: the lip runs against the rotating shaft while the outer diameter seats in the housing, keeping lubricant in and contaminants out. With a 11.12 mm shaft, a 22.22 mm housing bore and a 9.52 mm height, it fits compact assemblies where there is little room along the axis, such as small pumps, low-power motors, gearboxes and portable tools.

Reading the code is straightforward. The 9573 number identifies the seal, and the three figures that follow describe the cavity it is made for: shaft 11.12 mm, housing 22.22 mm, width 9.52 mm. The Mx designation refers to the lip profile. Because the bore is 22.22 mm and the section is just under 9.5 mm, this seal suits standardized seats found in small equipment rather than in large housings.

You will typically find this size in small centrifugal pumps, low-power electric motors, hollow-shaft gearboxes, compact gear cases, small compressors and portable power tools. It also appears in transmission units that need oil or grease kept apart from the surrounding environment. In every case the seal is what protects the bearings and holds the lubricant where it belongs; lubricant loss is a frequent reason bearings fail early.

Installation decides how long the seal lasts. Inspect the shaft first for burrs or a worn sealing track, and make sure the housing bore is clean and free of dents. Coat the lip with the same oil or grease the equipment uses, then press the seal in with a tube or spacer that contacts the outer diameter only, never the lip. If the shaft already shows a deep groove, a seal with the lip in a different position can help you avoid the same failure again.

To get a quote, send the part number 9573 or the three dimensions together with a photo of the old seal. The number marked on the seal or the model of the machine it came from also helps. Our team reviews the options in the radial shaft seal range and confirms which one fits without machining changes. MR Industrial Accessories serves customers throughout the United States and in several Latin American countries, and supplies the DBH brand.
