The DBH 5647 is a radial lip seal built to hold lubricant inside a housing and keep dust, water and particles out of rotating equipment. It follows the Mz configuration: one sealing lip, a metal outer case and a spring that keeps the lip pressed against the shaft. Shaft 52.40 mm, housing bore 73.02 mm, height 9.52 mm. MR Industrial Accessories supplies this brand and helps you match the seal to your application.

The code breaks down into two parts: Mz tells you the design, and 5647 identifies the size within the DBH line. In the Mz design the case is metal and the lip is a single element, so the seal presses into a cylindrical housing bore. The elastomer is chosen to stand up to mineral oils and greases, and the internal spring compensates for normal lip wear over time. This is a common replacement item on rotating shafts.

You will find this seal in gearboxes, centrifugal pumps, electric motors, transmission shafts and machinery rollers. Its job is dual: stop oil from escaping and stop contaminants from reaching bearings and gears. The 9.52 mm height helps in assemblies where there is not much axial room to fit a wider seal. Continuous-process equipment is where this kind of sealing reliability matters most.

Checking fit before installation saves time. Confirm that the shaft and housing bore match the values above, and that the shaft surface is ground, with no splines or burrs that could cut the lip. Lubricate the lip with the system oil, check that the spring sits correctly, then press the seal in with even force on the outer diameter. A press or rubber mallet works; avoid hitting the lip, and keep the bore clean and burr-free.

If you need a cross-reference, send code 5647 or the shaft and housing dimensions you measured. We compare them against the manufacturer's data and suggest options from the same brand or from other lines we carry. We can also help when the original seal is a special design or the housing shows wear. The goal is to keep your equipment running instead of waiting on a sealing part.
