When a rotating shaft needs its lubricant kept in and outside contamination kept out, the DBH 6009 lip seal does that job. It seats in the housing bore and its elastomeric lip rides against the shaft, holding a dynamic seal while the machine runs. The Mz design pairs that lip with a metal body that presses into place. Shaft 63.5 mm, housing 88.9 mm, height 12.70 mm. MR Industrial Accessories supplies this seal as a brand item.

The reference breaks down simply. DBH is the seal line, and 6009 identifies this particular size and design. Read the three figures in the usual order: the first is the shaft it runs on, the second is the bore it presses into, and the third is how much axial room it needs. On this seal that means shaft 63.5 mm, housing 88.9 mm and height 12.70 mm. The Mz configuration is a lip seal with a metal case, a standard replacement item rather than a made-to-order part. Inside, a spring keeps the lip pressed against the shaft, and the lip compound is chosen to stand up to industrial oils and greases.

You will find seals of this size in gearboxes and speed reducers, centrifugal pumps, electric motors and other transmission equipment. Their function is the same everywhere: hold the lubricant where the bearings and gears need it, and keep dust and moisture from working their way in. Fan, mixer and conveyor shafts in dirty or damp areas also use them. Before fitting one, confirm the lip material suits the fluid in the machine and the temperature it reaches in service.

Installation is where most seal problems start. The housing bore should be clean and free of burrs or scratches, and the shaft surface under the lip should not be worn. Wiping the lip with the same oil or grease the equipment runs on helps it seat without running dry. Press the seal in with a tool that pushes on the outer diameter, keeping it square to the bore. The 12.70 mm height tells you how much axial space the seat has to provide. If the shaft shows a worn track, moving the lip to a fresh position or fitting a repair sleeve are options worth reviewing.

Looking for a replacement or an equivalent? Send the code 6009 or your measured shaft, housing and height values. With those numbers we can check the DBH line or another brand we carry. If the Mz design does not suit your application, we can point you toward a different lip geometry or compound. Sending a photo of the old seal or caliper readings speeds up confirmation of the reference and the quote.

Quotes are handled by WhatsApp or email at MR Industrial Accessories. Send the code or the dimensions, and we will confirm the reference and reply promptly. Our team also helps with selection and installation questions and can suggest equivalents when the original part is hard to identify.
