When a shaft needs to hold lubricant in and keep dust, water and particles out, a radial shaft seal is the part doing that work. The DBH 5550 is built for exactly this duty, with a metal outer case that presses into the housing bore and a sealing lip that rides against the rotating shaft. Its three key measurements are a 35.80 mm shaft, a 68 mm housing bore and a 12 mm width. MR Industrial Accessories supplies this brand and can help you confirm the size before you order.

The designation 5550 identifies this seal within the DBH line. In the Mz configuration, the elastomeric lip is bonded to a metal case: the case holds the seal firmly in the bore, while the lip contacts the shaft to close off the gap between the rotating and stationary parts. Maintenance teams treat it as a standard wear item, so it is usually replaced during a bearing change or whenever a leak appears at the shaft exit.

You will find this size in gearboxes and reducers, centrifugal pumps, electric motors and other power transmission assemblies. It also shows up on fan, mixer and conveyor shafts, where keeping oil or grease where it belongs protects the bearings on either side. In every case the job is the same: retain the lubricant and block contaminants from reaching the interior of the assembly.

Before installing a seal like the DBH 5550, confirm the three dimensions match your equipment: shaft 35.80 mm, housing bore 68 mm, width 12 mm. The shaft surface should be clean and free of burrs, nicks or scratches, and a light film of lubricant on the lip helps it seat without damage. Press the metal case in squarely, perpendicular to the shaft, and apply force to the case rather than the lip. If the application runs hot or with strong vibration, ask about other lip profiles or materials.

If you are replacing a worn seal or crossing a reference, the quickest route is to send the code 5550 or the dimensions you measured. From there we can locate a match within the same family or propose a seal with compatible measurements. We can also review lip type and material against the fluid and the operating conditions. Message us on WhatsApp or by email and the team will reply promptly with the best fit.

MR Industrial Accessories works with seals and oil seals for industrial maintenance and replacement across the United States and Latin America. If the DBH 5550 is not an exact match for your application, send the code or the dimensions and we will help you identify the right part from our seal range.
